Purification and properties of an alginate lyase from a marine bacterium. (1/937)

An unidentified pseudomonad isolated by enrichment procedures from decomposing seaweed was grown in defined medium containing sodium alginate as the sole carbon source. The alginate lyase recovered from disrupted bacterial cells was purified by a procedure of (NH4)2SO4 precipitation, gel filtration and ion-exchange chromatography. From sodium dodecyl sulphate/polyacrylamide-gel-electrophoresis experiments a mol.wt. of about 50 000 was determined. The enzyme was active against both algal and bacterial alginate preparations. Kinetic studies together with analysis of the unsaturated oligouronide products of alginate lyase action indicated the enzyme was specific for guluronic acid-containing regions of the macromolecular substrate. The specificity of the enzyme can be used to give information about the primary composition of alginate samples.  (+info)

Matrix degradation by chondrocytes cultured in alginate: IL-1 beta induces proteoglycan degradation and proMMP synthesis but does not result in collagen degradation. (2/937)

OBJECTIVE: To determine the role of interleukin-1 beta (IL-1 beta) in the degradation of proteoglycans and collagen by articular chondrocytes. DESIGN: Chondrocytes were cultured in alginate beads for 2 weeks to produce extracellular matrix, followed by the addition of IL-1 beta for 1 or 2 days. Breakdown of extracellular matrix (with and without activation of pro-matrix metalloproteinases (MMPs) by APMA) was monitored by release of glycosaminoglycans (GAG, proteoglycans) and hydroxyproline (collagen) from the beads into the medium, and by the amount of damaged collagen in the bead. Levels of (pro)MMPs in the beads were assayed by zymography and their activity was quantified fluorometrically. RESULTS: IL-1 beta induced a profound GAG release (approximately 80% after 2 days at 20 ng/ml IL-1 beta) that was both time and IL-1 beta concentration dependent. Under these conditions no increase in collagen release or damaged collagen in the bead was detected. Zymography demonstrated that the synthesis of a variety of proMMPs was induced by IL-1 beta, without a detectable increase of MMP-activity as measured in the activity assay. After activation of the proMMPs by APMA, a time and IL-1 beta concentration-dependent increase in MMP-activity was found, which resulted in almost complete deterioration of collagen already after 18 h of incubation. In the presence of APMA, GAG release from IL-1 beta treated beads was significantly increased from 24 to 31%. CONCLUSIONS: Our data suggest that proteoglycan and collagen degradation are regulated through different mechanisms: IL-1 beta induces the synthesis of active enzymes that degrade proteoglycans, such as 'aggrecanase', and inactive proMMPs. Thus, IL-1 beta alone is not sufficient to result in collagen-degrading MMPs. Once activated, MMPs may account for up to a quarter of the aggrecan degradation in this model.  (+info)

Factors affecting dimensional instability of alginate impressions during immersion in the fixing and disinfectant solutions. (3/937)

To clarify the factors determining the dimensional stability of alginate impressions during immersion in disinfectant and fixing solution, the weight change of impressions in solutions of glutaraldehyde (GA), NaClO, Na2SO4, K2SO4, CaCl2, and ZnSO4 was measured. In the nonelectrolytic solution, GA, the weight decreased in proportion to concentration, possibly due to the gradient of osmotic pressure between the impression and solution. In monovalent metallic salt solutions the weight change decreased with increased concentration. Especially at lower concentrations the rate of weight loss was high. A chemical action of the solution might also be involved, in addition to the osmotic pressure difference. The weight loss in divalent metallic salt solutions was greater than in monovalent solutions, implicating crosslinking reactions between the impression and solution.  (+info)

Study of the response of a biofilm bacterial community to UV radiation. (4/937)

We have developed a bioluminescent whole-cell biosensor that can be incorporated into biofilm ecosystems. RM4440 is a Pseudomonas aeruginosa FRD1 derivative that carries a plasmid-based recA-luxCDABE fusion. We immobilized RM4440 in an alginate matrix to simulate a biofilm, and we studied its response to UV radiation damage. The biofilm showed a protective property by physical shielding against UV C, UV B, and UV A. Absorption of UV light by the alginate matrix translated into a higher survival rate than observed with planktonic cells at similar input fluences. UV A was shown to be effectively blocked by the biofilm matrix and to have no detectable effects on cells contained in the biofilm. However, in the presence of photosensitizers (i.e., psoralen), UV A was effective in inducing light production and cell death. RM4440 has proved to be a useful tool to study microbial communities in a noninvasive manner.  (+info)

The A modules of the Azotobacter vinelandii mannuronan-C-5-epimerase AlgE1 are sufficient for both epimerization and binding of Ca2+. (5/937)

The industrially important polysaccharide alginate is composed of the two sugar monomers beta-D-mannuronic acid (M) and its epimer alpha-L-guluronic acid (G). In the bacterium Azotobacter vinelandii, the G residues originate from a polymer-level reaction catalyzed by one periplasmic and at least five secreted mannuronan C-5-epimerases. The secreted enzymes are composed of repeats of two protein modules designated A (385 amino acids) and R (153 amino acids). The modular structure of one of the epimerases, AlgE1, is A1R1R2R3A2R4. This enzyme has two catalytic sites for epimerization, each site introducing a different G distribution pattern, and in this article we report the DNA-level construction of a variety of truncated forms of the enzyme. Analyses of the properties of the corresponding proteins showed that an A module alone is sufficient for epimerization and that A1 catalyzed the formation of contiguous stretches of G residues in the polymer, while A2 introduces single G residues. These differences are predicted to strongly affect the physical and immunological properties of the reaction product. The epimerization reaction is Ca2+ dependent, and direct binding studies showed that both the A and R modules bind this cation. The R modules appeared to reduce the Ca2+ concentration needed for full activity and also stimulated the reaction rate when positioned both N and C terminally.  (+info)

Regulation of alginate biosynthesis in Pseudomonas syringae pv. syringae. (6/937)

Both Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate. However, the environmental signals that trigger alginate gene expression in P. syringae are different from those in P. aeruginosa with copper being a major signal in P. syringae. In P. aeruginosa, the alternate sigma factor encoded by algT (sigma22) and the response regulator AlgR1 are required for transcription of algD, a gene which encodes a key enzyme in the alginate biosynthetic pathway. In the present study, we cloned and characterized the gene encoding AlgR1 from P. syringae. The deduced amino acid sequence of AlgR1 from P. syringae showed 86% identity to its P. aeruginosa counterpart. Sequence analysis of the region flanking algR1 in P. syringae revealed the presence of argH, algZ, and hemC in an arrangement virtually identical to that reported in P. aeruginosa. An algR1 mutant, P. syringae FF5.32, was defective in alginate production but could be complemented when algR1 was expressed in trans. The algD promoter region in P. syringae (PsalgD) was also characterized and shown to diverge significantly from the algD promoter in P. aeruginosa. Unlike P. aeruginosa, algR1 was not required for the transcription of algD in P. syringae, and PsalgD lacked the consensus sequence recognized by AlgR1. However, both the algD and algR1 upstream regions in P. syringae contained the consensus sequence recognized by sigma22, suggesting that algT is required for transcription of both genes.  (+info)

Biodegradable alginate microspheres as a delivery system for naked DNA. (7/937)

Sodium alginate is a naturally occurring polysaccharide that can easily be polymerized into a solid matrix to form microspheres. These biodegradable microspheres were used to encapsulate plasmid DNA containing the bacterial beta-galactosidase (LacZ) gene under the control of either the cytomegalovirus (CMV) immediate-early promoter or the Rous sarcoma virus (RSV) early promoter. Mice inoculated orally with microspheres containing plasmid DNA expressed LacZ in the intestine, spleen and liver. Inoculation of mice with microspheres containing both the plasmid DNA and bovine adenovirus type 3 (BAd3) resulted in a significant increase in LacZ expression compared to those inoculated with microspheres containing only the plasmid DNA. Our results suggest that adenoviruses are capable of augumenting transgene expression by plasmid DNA both in vitro and in vivo.  (+info)

R-factor inheritance and plasmid content in mucoid Pseudomonas aeruginosa. (8/937)

Eighteen strains of alginate-producing mucoid Pseudomonas aeruginosa were evaluated with respect to plasmid content and the ability to maintain well-characterized R plasmids. The spontaneous loss of alginate production in these strains varied from 0.01 to 0.7% and was not significantly increased by plasmid curing regimens. Examination of cleared lysates of these strains and their isogenic nonmucoid derivatives by agarose gel electrophoresis failed to reveal plasmid DNA. R-plasmid (P-incompatibility-group) transfer to mucoid P. aeruginosa was unaffected by the presence of the alginate capsule. Maintenance and expression of such plasmids in the mucoid strains were confirmed by agarose gel electrophoresis and by verification of plasmid-linked drug resistance and pilus-specific bacteriophage sensitivity. These studies demonstrate that alginate production does not appear to be plasmid linked and that mucoid P. aeruginosa are capable of receiving and donating certain drug resistance plasmids. Since some of the plasmids used here have been shown to mobilize chromosomal DNA, strains constructed in this study should afford the means for exploring the genetic basis of the mucoid phenotype.  (+info)

Calcium alginate - WikipediaCalcium alginate - Wikipedia
Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture. Alginate is usually the salts of alginic acid, but it can also refer to derivatives of alginic acid and alginic acid itself; in some publications the term algin is used instead of alginate. Alginate is present in the cell walls of brown algae, as the calcium, magnesium and sodium salts of alginic acid. To extract the alginate, the seaweed is broken into pieces and stirred with a hot solution of an alkali, usually sodium carbonate. Over a period of about two hours, the alginate dissolves as sodium alginate to give a very thick slurry. This slurry also contains the part of the seaweed that does not dissolve, mainly cellulose. This insoluble residue must be removed from the solution. The solution is too thick ...

Property of Alginate - IRO Alginate Industry Co., Ltd.Property of Alginate - IRO Alginate Industry Co., Ltd.
Like many natural polysaccharides, dried alginates are not stable to heat, oxygen, metallic ions, etc. Stored in such circumstances, alginates will be degraded naturally. The high-viscosity alginate is more rapidly degraded than the medium-or low- viscosity ones. The order of stability in storage is: sodium alginate , ammonium alginate , alginic acid.. Different kind of alginate salt gives different stability, so does the different grade product. The industrial grade alginate solution is more easily degraded by microbe in the air, because such products contain much algal particles and nitrogenous matter which offer plenty of nutrition for microbe. The pure sodium alginate solution can be kept at room temperature for several months without obvious change in viscosity. When temperature increases, all alginate solutions will depolymerize. Alginate solutions are stable in the pH range 5.5 - 10 at room temperature for a long time, but will form the gel below pH 5.5. Propylene glycol alginate solution ...

Adsorption of ochratoxin A from grape juice by yeast cells immobilised in calcium alginate beadsAdsorption of ochratoxin A from grape juice by yeast cells immobilised in calcium alginate beads
Grape juice can be easily contaminated with ochratoxin A (OTA), one of the known mycotoxins with the greatest public health significance. Among the different approaches to decontaminate juice from this mycotoxin, microbiological methods proved efficient, inexpensive and safe, particularly the use of yeast or yeast products. To ascertain whether immobilisation of the yeast biomass would lead to successful decontamination, alginate beads encapsulating Candida intermedia yeast cells were used in our experiments to evaluate their OTA-biosorption efficacy. Magnetic calcium alginate beads were also prepared by adding magnetite in the formulation to allow fast removal from the aqueous solution with a magnet. Calcium alginate beads were added to commercial grape juice spiked with 20μg/kg OTA and after 48h of incubation a significant reduction (,80%), of the total OTA content was achieved, while in the subsequent phases (72-120h) OTA was slowly released into the grape juice by alginate beads. ...

Adhesion and growth of bone marrow stromal cells on modified alginate hydrogels. - Nuffield Department of Orthopaedics,...
Alginate is a biodegradable, immunocompatible biopolymer that is capable of immobilizing viable cells and bioactive factors. Few investigations have analyzed the efficacy of alginate gels as substrata for cell attachment and proliferation. Here we have compared the adhesion and subsequent growth of human and rat bone marrow stromal fibroblastic cells on unmodified alginate hydrogel surfaces. It was found that, in contrast to rat cells, human cells did not readily attach or proliferate on unmodified alginates. In attempts to enhance these features, or collagen type I was incorporated into the gels, with no significant improvements in prolonged human cell adherence. However, alginate gels containing both collagen type I and beta-tricalcium phosphate were found to enhance human cell adherence and proliferation. Furthermore, interactions between the collagen and beta-tricalcium phosphate prevented loss of the protein from the hydrogels. These results indicate that alginate gels containing collagen have

Designing calcium alginate for ex vivo expansion of hematopoietic stem cells. | DR-NTUDesigning calcium alginate for ex vivo expansion of hematopoietic stem cells. | DR-NTU
This study explores the utility of calcium-alginate hydrogels as a three-dimensional culture platform for hematopoietic cell culture. We investigate the effects of calcium concentration and alginate viscosity on the mechanical and physical properties of the gel, and their subsequent effects on cellular growth. Further, we have also explored the establishment of a co-culture system in the presence of stromal cells (HS-5) and using K562 cells as our hematopoietic model. Physical characterization of calcium alginate is conducted with mechanical testing and Scanning Electron Microscope (SEM) scans to determine the relationship between the mechanical strength and the structure of calcium alginate with the variation of calcium concentration and alginate viscosity. The study on mechanical properties via compressive stress test reveals that increasing calcium concentration and alginate viscosity resulted in the formation of stiffer gels as showed by the higher elastic moduli. In addition, SEM scans ...

Impact of solvent quality on the network strength and structure of alginate gelsImpact of solvent quality on the network strength and structure of alginate gels
The influence of the mixture of water and alcohols on the solubility and properties of alginate and its calcium-induced gels is of interest for the food, wound care and pharmaceutical industries. The solvent quality of water with increasing amounts of ethanol (0-20%) on alginate was studied using intrinsic viscosity. The effect of ethanol addition on the rheological and mechanical properties of calcium alginate gels was determined. Small-angle X-ray scattering and transmission electron microscopy were used to study the network structure. It is shown that the addition of ethanol up to 15% (wt) increases the extension of the alginate chain, which correlates with increased moduli and stress being required to fracture the gels. The extension of the polymer chain is reduced at 20% (wt) ethanol, which is followed by reduced moduli and stress at breakage of the gels. The network structure of gels at high ethanol concentrations (24%) is characterized by thick and poorly connected network strands.. ...

Alginate hydrogels are commonly used in biomedical applications such as scaffolds for tissue engineering, drug delivery, and as a medium for cell immobilization. Multivalent cations are often employed to create physical crosslinks between carboxyl and hydroxyl moieties on neighbouring polysaccharide chains, creating hydrogels with a range of mechanical properties. This work describes the manufacture and characterisation of sodium alginate hydrogels using the divalent cations Mg2+, Ca2+ and Sr2+ to promote gelation via non-covalent crosslinks. The gelation time and Youngs modulus are characterised as a function of cation and alginate concentrations. The implications of this work towards the use of environmental elasticity to control stem cell differentiation are discussed.. ...

Safety and efficacy of sodium and potassium alginate for pets, other non food-producing animals and fish | European Food Safety...Safety and efficacy of sodium and potassium alginate for pets, other non food-producing animals and fish | European Food Safety...
Sodium and potassium alginate are intended to be used as technological additives (functional groups: emulsifiers, stabilisers, thickeners, gelling agents and binders). Sodium alginate is intended to be used in feedingstuffs for pets, other non food-producing animals and fish, with no maximum recommended use level. Potassium alginate is intended to be used in feedingstuffs for cats and dogs at levels up to 40,000 mg/kg feed (on dry matter). Since the functional properties of the additives are determined by the alginate content, sodium and potassium alginate were considered equivalent. The maximum dose considered safe for cats, dogs, other non food-producing animals, salmonids and other fish is 40,000 mg alginates (sodium and potassium salts)/kg complete feed. The use of alginates in feedingstuffs for fish is of no concern for the consumer. Alginates are reported not to be irritant to the skin but mildly irritant to the eyes.

Sodium Alginate Acrylic Hard Ground: Experiment 3 | Zea Mays PrintmakingSodium Alginate Acrylic Hard Ground: Experiment 3 | Zea Mays Printmaking
Humidity: sunny, mild humidity Using our observations from Experiment #2, we decided to start with a 1:24 ratio of sodium alginate to Future floor polish because this ratio produced a solution with the right combination of fluidity and thickness for a ground.. To begin the experiment we mixed ½ tbs of Sodium alginate and ¾ cup of Zea Mays Stop out to achieve a 1:24 ratio.. This mixture was not fluid like we expected. It immediately started clumping up and became thicker than we anticipated. We hypothesized the different results were due to addition of Gac 100, which is part of the stop out mixture. The Gac 100 was not included in our first test with a 1:24 ratio. In the first test, just future floor polish was mixed with sodium alginate. We let the sodium alginate and stop out mixture sit for three hours to see if over time the clumps would dissolve. After three hours of sitting with periodic stirring, the mixture was still very lumpy and thick. This ratio,1 part sodium alginate to 24 parts ...

IDEALS @ Illinois: Over-expression and characterization of four alginate lyases from vibrio splendidus 12B01IDEALS @ Illinois: Over-expression and characterization of four alginate lyases from vibrio splendidus 12B01
lginate is a polysaccharide found within brown seaweeds and has been targeted as a carbon source for biofuel production. Alginate consists of α-L-guluronate (G) and β-D-mannuronate (M) linked in various patterns, which results in either a homo- or heteropolymeric structure. Alginate lyases are enzymes that degrade the linkage between G and M blocks and can have specificity to either polyG, polyM, or polyMG block degradation. The marine bacterium Vibrio splendidus 12B01 contains four putative alginate lyases which were investigated in this study. We identified, purified, and characterized the four PL7 alginates lyases. We found that these lyases have optimal activity between pH 7.5-8.5 and 20-25°C, consistent with use in a marine environment. Additionally, Ca 2+ is necessary for optimal enzyme activity. The binding constant (K m ) of the lyases toward alginate was found to be between 22 and 123 mM alginate and the maximum reaction rate (V max ) was found to be between 0.13 and 0.83 μM s -1 . ...

PY - 2005/5. Y1 - 2005/5. N2 - Degradability is often a critical property of materials utilized in tissue engineering. Although alginate, a naturally derived polysaccharide, is an attractive material due to its biocompatibility and ability to form hydrogels, its slow and uncontrollable degradation can be an undesirable feature. In this study, we characterized gels formed using a combination of partial oxidation of polymer chains and a bimodal molecular weight distribution of polymer. Specifically, alginates were partially oxidized to a theoretical extent of 1% with sodium periodate, which created acetal ...

Alginate films augmented with chlorhexidine hexametaphosphate particles provide sustained antimicrobial properties for...
All chronic wounds are colonised by bacteria; for some, colonisation progresses to become infection. Alginate wound dressings are used for highly exuding chronic wounds as they are very absorbent, taking up large quantities of exudate while maintaining a moist wound bed to support healing. Some alginate dressings are doped with antimicrobials, most commonly silver, but evidence regarding the efficacy of these is largely inconclusive. This manuscript describes the development and in vitro assessment of alginate materials doped with chlorhexidine hexametaphosphate (CHX-HMP), a sparingly soluble salt which when exposed to aqueous environments provides sustained release of the common antiseptic chlorhexidine. Comparator materials were a commercial silver alginate dressing material and an alginate doped with chlorhexidine digluconate (CHXdg). CHX-HMP alginates provided a dose-dependent CHX release which was sustained for over 14 days, whereas CHXdg alginates released limited CHX and this ceased ...

Wound dressings made from bacterial alginate - Bio-based News - The portal for bio-based economy & industrial biotechnologyWound dressings made from bacterial alginate - Bio-based News - The portal for bio-based economy & industrial biotechnology
Research work that began in 2013 has been able to establish, optimise and standardise the cultivation of the soil bacterium and the biotechnological process for producing and isolating bacterial alginates. By working specifically on optimising the bacteriums alginate biosynthesis, the researchers succeeded in improving the composition, and therefore the properties and yield of the alginate. This meant that they could make customised alginates that are particularly suitable for producing fibres for use in medical products. In a pilot production facility, the research partners were able to spin fibres from alginate and alginate-viscose, and turn them into innovative nonwoven materials and wound dressings within the established process. When the new wound dressings were tested in use, the alginate product that had been made using biotechnology was impressive for its liquid absorption capacity, which was significantly better than that of commercially available marine alginate-based wound dressings. ...

Magiran | The Effect of Calcium Alginate Entrapment on the Stability of Novel Lipases from P. Reinekei and P. brenneriMagiran | The Effect of Calcium Alginate Entrapment on the Stability of Novel Lipases from P. Reinekei and P. brenneri
The high cost of soluble enzymes can limit their use for commercial and industrial purposes. Immobilization can enhance enzyme reusability, thereby reducing product isolation costs and overcoming this economic barrier. In the current study, two novel, purified lipases from Pseudomonas sp. (Pseudomonas reinekei and Pseudomonas brenneri) were entrapped in a calcium alginate matrix, with the aim of simultaneously enhancing enzyme reusability and stability. Following entrapment, the retained activity of the enzyme-alginate composite was verified by an enzymatic hydrolysis reaction of a p-nitrophenol palmitate substrate. The effect of the enzyme-alginate entrapment against various physiochemical parameters such as pH, temperature, metal ions, and solvents were subsequently examined. The entrapment was found to have minimal beneficial stability gains. However, enhanced enzyme reusability (up to 3 cycles) and stability (up to 18 days at 4°C) of the calcium alginate entrapped lipase, as indicated by

The relationship of high and low molecular weight mannuronic acid (M)- and guluronic acid (G)-rich alginate nanoparticles as oral insulin carrier was elucidated. Nanoparticles were prepared through ionotropic gelation using Ca2 +, and then in vitro physicochemical attributes and in vivo antidiabetic characteristics were examined. The alginate nanoparticles had insulin release retarded when the matrices had high alginate-to-insulin ratio or strong alginate-insulin interaction via O-H moiety. High molecular weight M-rich alginate nanoparticles were characterized by assemblies of long polymer chains that enabled insulin encapsulation with weaker polymer-drug interaction than nanoparticles prepared from other alginate grades. They were able to encapsulate and yet release and have insulin absorbed into systemic circulation, thereby lowering rat blood glucose. High molecular weight G- and low molecular weight M-rich alginate nanoparticles showed remarkable polymer-insulin interaction. This retarded ...

This review provides a critical update on human and animal studies investigating the effect of alginate supplementation on appetite regulation, glycaemic and insulinemic responses, and lipid metabolism with discussion of the evidence on potential mechanisms, efficacy and tolerability. Dependent on vehicle applied for alginate supplementation, the majority of animal and human studies suggest that alginate consumption does suppress satiety and to some extent energy intake. Only one long-term intervention trial found effects on weight loss. In addition, alginates seem to exhibit beneficial influence on postprandial glucose absorption and insulin response in animals and humans. However, alginate supplementation was only found to have cholesterol-lowering properties in animals. Several mechanisms have been suggested for the positive effect observed, which involve delayed gastric emptying, increased viscosity of digesta and slowed nutrient absorption in the small intestine upon alginate gel formation. ...

NTNU Open: Study of Rat Olfactory Ensheathing Cells in Alginate based MatricesNTNU Open: Study of Rat Olfactory Ensheathing Cells in Alginate based Matrices
Alginate hydrogel made from alginate and crosslinking divalent ions is a natural biomaterial that is biocompatible, has low toxicity, is relatively cheap and has mild gelation chemistry. It is a porous material that allows diffusion of small molecules. Alginate hydrogel is a polymeric network that contains 95-99% water and it does in many ways resemble the natural extracellular matrix (ECM) that surrounds cells in the body. It is also hydrophilic, which reduces friction in body fluids and minimizes protein adsorption and it is easily stored and sterilized.Alginate is produced by both algae and bacteria, and it is initially synthesized as mannuronan (M) with 100% M-residues. Guluronic acid residues (G) are introduced in a post-polymerization step by enzymes called mannuronan C-5 epimerases that catalyze conversion of M into G without breaking the glycosidic bond. Seven different mannuronan C-5 epimerases have been sequenced, cloned and produced recombinantly, and these enzymes introduce ...

Here, we sought to develop a cell culture surface conversion technique that would not damage living cells. An alginate thin film, formed on a glass plate by spin coating of sodium alginate solution and dipping into calcium chloride solution, was used to inhibit adhesion of cells. The film could be removed by ethylenediaminetetraacetate (EDTA) at any time during cell culture, permitting observation of cellular responses to conversion of the culture surface in real time. Additionally, we demonstrated the validity of the alginate thin film coating method and the performance of the film. The thickness of the alginate thin film was controlled by varying the rotation speed during spin coating. Moreover, the alginate thin film completely inhibited the adhesion of cultured cells to the culture surface, irrespective of the thickness of the film. When the alginate thin film was removed from the culture surface by EDTA, the cultured cells adhered to the culture surface, and their morphology changed. ...

A two-phase model for determining the stability constants for interactions between copper and alginic acidA two-phase model for determining the stability constants for interactions between copper and alginic acid
The two-phase model used previously to calculate the polymer-subphase volume of alginic acid was applied to interpret the dependence of apparent metal binding equilibrium on environmental conditions. In this model, the polymer subphase, a small aqueous region surrounding the polymer chain, was considered as a separate phase in the aqueous solution and as a protonation-deprotonation and metal binding reaction zone. Three factors were taken into account when treating experimental data: (1) the electric field due to the charged ligands on the polymer molecule, (2) the effective concentration of ligands based on polymer-subphase volume, and (3) the competition from hydrogen ions for the metal binding sites. The data of base titration of alginic acid in the presence of trace amounts of copper at different alginic acid concentrations and ionic strengths yielded unique intrinsic stability constants for complexes formed between a cupric ion and one or two binding ligands ...

Dolomite Microfluidics systems are enabling reliable, reproducible production of monodisperse alginate beads, overcoming the challenges associated with traditional batch techniques. Controlled and reproducible generation of alginate gel beads is crucial for biomedical science and engineering applications that require biologically and chemically inert polymers, such as the encapsulation of drugs or cells. However, this can be difficult to achieve with batch synthesis, which produces large beads with a wide size distribution and minimal control over bead size. The reproducibility and throughput of the technique are also low. Microfluidic synthesis of alginate beads overcomes these difficulties, allowing precise control of bead formation and enabling rapid production of particles with well-defined sizes, shapes and morphologies ...

Alginic acid - WikipediaAlginic acid - Wikipedia
Alginic acid, also called algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. It is also a significant component of the biofilms produced by the bacterium Pseudomonas aeruginosa, the major pathogen in cystic fibrosis, that confer it a high resistance to antibiotics and killing by macrophages. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms. Alginic acid is a linear copolymer with homopolymeric blocks of (1-4)-linked β-D-mannuronate (M) and its C-5 epimer α-L-guluronate (G) residues, respectively, covalently linked together in different sequences or blocks. The monomers can appear in homopolymeric blocks of consecutive G-residues (G-blocks), consecutive M-residues (M-blocks) or alternating M and G-residues (MG-blocks). Alginates are refined from brown seaweeds. A wide variety of brown seaweeds of the phylum Phaeophyceae are harvested ...

Daily ingestion of alginate reduces energy intake in free-living subjects - Sheffield Hallam University Research ArchiveDaily ingestion of alginate reduces energy intake in free-living subjects - Sheffield Hallam University Research Archive
Sodium alginate is a seaweed-derived fibre that has previously been shown to moderate appetite in models of acute feeding. The mechanisms underlying this effect may include slowed gastric clearance and attenuated uptake from the small intestine. In order to assess whether alginate could be effective as a means of appetite control in free-living adults, 68 males and females (BMI range: 18.50-32.81 kgl M-2) completed this randomised, controlled two-way crossover intervention to compare the effects of 7 day daily ingestion of a strong-gelling sodium alginate formulation against a control. A sodium alginate with a high-guluronate content was chosen because, upon ingestion, it forms a strong gel in the presence of calcium ions. Daily preprandial ingestion of the sodium alginate formulation produced a significant 134.8 kcal (7%) reduction in mean daily energy intake. This reduced energy intake was underwritten by significant reductions in mean daily carbohydrate, sugar, fat, saturated fat and protein ...

The history of Alginate chemistry - Bacterial | CyberColloidsThe history of Alginate chemistry - Bacterial | CyberColloids
Alginate can be produced by a microbial fermentation using bacteria such as Azobacter Vinelandii and Pseudomonas Aeruginosa (Linker and Jones 1964, Gorin and Spencer 1966). These bacteria produce a polysaccharide with a structure resembling alginate, differing only in that there are acetyl groups on a portion of the C2 and C3 hydroxyls. It is believed that the acetate groups are associated mainly with the D-mannuronic acid residues (Davidson 1977, Sutherland 1983, Paul 1986). The level of acetylation is variable as is the mannuronic and guluronic acid content. However the level of guluronic acid in the final polymer can be controlled to some extent by altering the level of calcium in the fermentation broth (Haug and Larsen 1971). The sequence structures and acetylation patterns of bacterial alginate, from different sources, have been studied with 2D COSY proton NMR techniques. The acetyl residues were found to be exclusively associated with the mannuronic acid residues with degrees of ...

Role of the Exopolysaccharide Alginate in Adherence to and Inflammatio by Brian E. CrossleyRole of the Exopolysaccharide Alginate in Adherence to and Inflammatio by Brian E. Crossley
Pseudomonas aeruginosa (PA) infections in Cystic Fibrosis (CF) patients are not easily cleared due to the conversion from a nonmucoid to a mucoid phenotype. Alginate is an acetylated exopolysaccharide produced by mucoid PA that is responsible for increased resistance to antibiotics, host phagocytic killing, and propagating biofilm formation. Understanding the interaction between PA and host cells is critical to understanding chronic infection and inflammation in CF. In order to investigate this, we used A549 pulmonary epithelial cells and murine alveolar macrophages (MH-S) to examine host response to nonmucoid versus mucoid PA infection. Adhesion assays in A549 pulmonary epithelial cells revealed that mucoid PA mutants adhere poorly compared to their nonmucoid counterparts. Similarly, phagocytosis assays using MH-S infected with PA revealed that mucoid PA are increasingly resistant to phagocytosis. The alginate acetylation mutant FRD1175 is more susceptible to phagocytic killing than alginate+ FRD1.
