Immobilization patterns and dynamics of acetate-utilizing methanogens immobilized in sterile granular sludge in upflow anaerobic sludge blanket reactors. (1/189)

Sterile granular sludge was inoculated with either Methanosarcina mazeii S-6, Methanosaeta concilii GP-6, or both species in acetate-fed upflow anaerobic sludge blanket (UASB) reactors to investigate the immobilization patterns and dynamics of aceticlastic methanogens in granular sludge. After several months of reactor operation, the methanogens were immobilized, either separately or together. The fastest immobilization was observed in the reactor containing M. mazeii S-6. The highest effluent concentration of acetate was observed in the reactor with only M. mazeii S-6 immobilized, while the lowest effluent concentration of acetate was observed in the reactor where both types of methanogens were immobilized together. No changes were observed in the kinetic parameters (Ks and mumax) of immobilized M. concilii GP-6 or M. mazeii S-6 compared with suspended cultures, indicating that immobilization does not affect the growth kinetics of these methanogens. An enzyme-linked immunosorbent assay using polyclonal antibodies against either M. concilii GP-6 or M. mazeii S-6 showed significant variations in the two methanogenic populations in the different reactors. Polyclonal antibodies were further used to study the spatial distribution of the two methanogens. M. concilii GP-6 was immobilized only on existing support material without any specific pattern. M. mazeii S-6, however, showed a different immobilization pattern: large clumps were formed when the concentration of acetate was high, but where the acetate concentration was low this strain was immobilized on support material as single cells or small clumps. The data clearly show that the two aceticlastic methanogens immobilize differently in UASB systems, depending on the conditions found throughout the UASB reactor.  (+info)

Resistance of artificial biofilms of Pseudomonas aeruginosa to imipenem and tobramycin. (2/189)

Viable cells of Pseudomonas aeruginosa were entrapped in alginate gel layers and incubated in a minimal glucose (15 g/L)-yeast extract (2 g/L)-salt medium to form artificial biofilm-like structures. After cultivation for 2 days, the biomass distribution inside the polymer was highly heterogeneous. The cell number reached approximately 1011 cells/g gel in the outer regions of the gel structures whereas the inner areas were less colonized (c. 10(8) cells g/gel). Killing of immobilized organisms by imipenem and tobramycin were compared with free-cell experiments (inoculum c. 10(9) cells/mL). Sessile-like bacteria displayed a higher resistance to the two antibiotics used alone or in combination than did suspended cells. Exposure for 10 h to 20 x MIC imipenem and 15 x MIC tobramycin reduced the number of viable immobilized bacteria to 0.3% and 3%, respectively, of the initial cell population, whereas these antibiotic concentrations were much more efficient (bactericidal) against free-cell cultures (5 log kill in 6 h). A synergic effect of tobramycin and imipenem was detected on bacterial suspensions but not on biofilm-like structures. Effective diffusivity measurements showed that the diffusion of imipenem in the alginate layer was not hindered. A slight but significant enhancement of beta-lactamase induction in immobilized cells as compared with their suspended counterparts was insufficient to explain the high resistance of sessile-like bacteria.  (+info)

Distribution of Nitrosomonas europaea and Paracoccus denitrificans immobilized in tubular polymeric gel for nitrogen removal. (3/189)

To improve the cooperative removal of nitrogen by Nitrosomonas europaea and Paracoccus denitrificans, we controlled their distribution in a tubular gel. When ethanol was supplied inside the tubular gel as an electron donor, their distributions overlapped in the external region of the gel. By changing the electron donor from ethanol to gaseous hydrogen, the distribution of P. denitrificans shifted to the inside of the tube and was separated from that of N. europaea. The separation resulted in an increase of the oxidation rate of ammonia by 25%.  (+info)

Survival of Bifidobacterium longum immobilized in calcium alginate beads in simulated gastric juices and bile salt solution. (4/189)

Bifidobacterium longum KCTC 3128 and HLC 3742 were independently immobilized (entrapped) in calcium alginate beads containing 2, 3, and 4% sodium alginate. When the bifidobacteria entrapped in calcium alginate beads were exposed to simulated gastric juices and a bile salt solution, the death rate of the cells in the beads decreased proportionally with an increase in both the alginate gel concentration and bead size. The initial cell numbers in the beads affected the numbers of survivors after exposure to these solutions; however, the death rates of the viable cells were not affected. Accordingly, a mathematical model was formulated which expressed the influences of several parameters (gel concentration, bead size, and initial cell numbers) on the survival of entrapped bifidobacteria after sequential exposure to simulated gastric juices followed by a bile salt solution. The model proposed in this paper may be useful for estimating the survival of bifidobacteria in beads and establishing optimal entrapment conditions.  (+info)

Identification of a novel glycoprotein-binding activity in Streptococcus pyogenes regulated by the mga gene. (5/189)

The interaction between Streptococcus pyogenes and the host cell surface is not completely understood. Characterization of the adhesion mechanisms of the bacterium to the host cell surface is needed in order to develop new vaccines and anti-adhesion drugs. The presence of glycoprotein-binding activities among streptococcal strains was investigated. An activity binding to thyroglobulin, fetuin, asialofetuin and mucin but not non-glycosylated proteins was found to be present in the majority of the S. pyogenes strains studied. Cross-inhibition experiments suggested that the glycoproteins share a common structure recognized by the bacteria. The glycoprotein-binding activity was found to be proteinaceous, tightly attached to the bacterial surface and it also mediated the adherence of bacteria to solid surfaces coated with glycoproteins. The activity was found by transposon mutagenesis and complementation to be regulated by the multiple-gene regulator Mga, which has been implicated as a regulator of S. pyogenes virulence factors.  (+info)

Adhesion of Candida albicans to oral streptococci is promoted by selective adsorption of salivary proteins to the streptococcal cell surface. (6/189)

Adhesion of Candida albicans to saliva-coated surfaces is an important early step in the colonization of the oral cavity. C. albicans cells also adhere to several species of oral streptococci including Streptococcus gordonii, Streptococcus oralis and Streptococcus sanguinis in what are believed to be multi-modal interactions. It is now demonstrated that incubation of streptococcal cells of these species with human parotid saliva further promotes the adhesion of C. albicans cells by up to 2-3-fold. Various species of streptococci were shown to adsorb different protein components of parotid saliva to their cell surfaces. The basic proline-rich proteins (bPRPs), to which C. albicans cells bind on nitrocellulose blot overlay, were strongly adsorbed to the surface of S. gordonii cells but not to S. oralis cells. Parotid saliva that was pre-adsorbed with S. gordonii cells and then applied to hydroxylapatite beads was <50% effective at supporting adhesion of C. albicans compared with control (non-adsorbed) saliva, demonstrating that bPRPs are major pellicle receptors. C. albicans cells did not adsorb bPRPs from fluid-phase parotid saliva. Following size-exclusion chromatography of parotid saliva samples, pooled fractions enriched in bPRPs promoted maximal adhesion of C. albicans to S. gordonii cells. The results demonstrate that C. albicans cells recognize only surface-bound forms of bPRPs and suggest that these proteins adsorbed to enamel or to streptococcal surfaces promote C. albicans adhesion and oral colonization.  (+info)

Response kinetics of tethered Rhodobacter sphaeroides to changes in light intensity. (7/189)

Rhodobacter sphaeroides can swim toward a wide range of attractants (a process known as taxis), propelled by a single rotating flagellum. The reversals of motor direction that cause tumbles in Eschericia coli taxis are replaced by brief motor stops, and taxis is controlled by a complex sensory system with multiple homologues of the E. coli sensory proteins. We tethered photosynthetically grown cells of R. sphaeroides by their flagella and measured the response of the flagellar motor to changes in light intensity. The unstimulated bias (probability of not being stopped) was significantly larger than the bias of tethered E. coli but similar to the probability of not tumbling in swimming E. coli. Otherwise, the step and impulse responses were the same as those of tethered E. coli to chemical attractants. This indicates that the single motor and multiple sensory signaling pathways in R. sphaeroides generate the same swimming response as several motors and a single pathway in E. coli, and that the response of the single motor is directly observable in the swimming pattern. Photo-responses were larger in the presence of cyanide or the uncoupler carbonyl cyanide 4-trifluoromethoxyphenylhydrazone (FCCP), consistent with the photo-response being detected via changes in the rate of electron transport.  (+info)

Propachlor removal by Pseudomonas strain GCH1 in an immobilized-cell system. (8/189)

A bacterial strain capable of growing on propachlor (2-chloro-N-isopropylacetanilide) was isolated from soil by using enrichment and isolation techniques. The strain isolated, designated GCH1, was classified as a member of the genus Pseudomonas. Washed-cell suspensions of strain GCH1 accumulated N-isopropylacetanilide, acetanilide, acetamide, and catechol. Pseudomonas strain GCH1 grew on propachlor with a generation time of 4.2 h and a rate of substrate utilization of 1.75 +/- 0.15 micromol h(-1). Gene expression did not require induction but was subject to catabolite expression. Acetanilide was a growth substrate with a yield of 0.56 +/- 0.02 mg of protein micromol(-1). GCH1 strain cells were immobilized by adsorption onto a ceramic support and were used as biocatalysts in an immobilized cell system. Propachlor elimination reached 98%, with a retention time of 3 h and an initial organic load of 0.5 mM propachlor. The viability of immobilized cells increased 34-fold after 120 days of bioreactor operation.  (+info)

A biosensor is proposed that contains bacteria that naturally effluxes potassium ions when threatened by electrophilic species. Pseudomonas aeruginosa is an activated sludge isolate and possesses the characteristic potassium efflux response. It has been immobilized in calcium alginate beads, photopolymer disks, and a thermally reversible gel in order to ultimately incorporate the immobilized system into a functional biosensor. The potassium efflux and cell viability were measured in the immobilized matrices. Wastewater treatment is of utmost importance; however, processes are easily upset. Upsets can be caused by various electrophiles found in the environment, and can cause serious health effects to people or the environment downstream from an upset. Electrophiles can cause the activated sludge in wastewater treatment facilities to deflocculate, and untreated water can be lost downstream. Devising a detection system for proactively sensing electrophiles prior to an upset is an important ...

Figure 1:Fluorescence images of PC3-GFP cells immobilized on ECM micro patterns of various shapes (the patterns are depicted by dashed lines).. Mastering the adhesion landscape of living cells on a surface is emerging as a new tool for investigating a lot of fundamental mechanisms of cell biology such as shape control, differentiation, division, polarity or motility. The common point of all these studies is the production of micro-patterns of various shapes and dimensions along which, adherent cells are immobilized in a deterministic way. The control of cell adhesion through technology allows the biologists to design specific scenarii and record how various living cells respond (neural, epithelial, tumoral and stem cells). Because technology allows reproducing identical precise patterns along well arranged periodical arrays, these experimental observations can be made systematically over large population of cells thus reaching a high level of representativeness. The micro-contact printing of ...

Description: The protein encoded by this gene is a component of the exocyst complex, a multi-protein complex essential for the polarized targeting of exocytic vesicles to specific docking sites on the plasma membrane. Though best characterized in yeast, the component proteins and the functions of the exocyst complex have been demonstrated to be highly conserved in higher eukaryotes. At least eight components of the exocyst complex, including this protein, are found to interact with the actin cytoskeletal remodeling and vesicle transport machinery. This interaction has been shown to mediate filopodia formation in fibroblasts. This protein has been shown to interact with the Ral subfamily of GTPases and thereby mediate exocytosis by tethering vesicles to the plasma membrane. Alternative splicing results in multiple transcript variants ...

If there is one person who is unimpressed with modern cell phones, particularly smart-phones, its Free Software movement founder, Richard Stallman. Stallman, who also created the GNU operating system, believes smart-phones are a threat to the freedom of users and has no intention of getting one himself. I dont have a cell phone, I wont carry a cell phone, Stallman says. Its Stalins dream. Cell phones are tools of Big Brother. Im not going to carry a tracking device that records where I go all the time, and Im not going to carry a surveillance device that can be turned on to eavesdrop.. Stallman is a believer in free technology, and he does not mean free as in not having to pay for it, but being able to use, alter and distribute it however one wishes to do so. Stallman began the Free Software movement back in the 1980s, and he remains the president of the organization too. Smart-phones are not the only commonplace pieces of technology that Stallman wants nothing to do with either ...

Biocatalytic asymmetric reductions with whole cells can offer high enantioselectivity, environmentally benign processes and energy-effective operations and thus are of great interest. The application of whole cell-mediated bioreduction is often restricted if substrate and product have low water solubility and/or high toxicity to the biocatalyst. Many studies have shown that a biphasic system is often useful in this instance. Hence, we developed efficient biphasic reaction systems with biocompatible water-immiscible ionic liquids (ILs), to improve the biocatalytic anti-Prelog enantioselective reduction of acetyltrimethylsilane (ATMS) to (R)-1-trimethylsilylethanol {(R)-1-TMSE}, which is key synthon for a large number of silicon-containing drugs, using immobilized Candida parapsilosis CCTCC M203011 cells as the biocatalyst. It was found that the substrate ATMS and the product 1-TMSE exerted pronounced toxicity to immobilized Candida parapsilosis CCTCC M203011 cells. The biocompatible water-immiscible ILs
β-Fructofuranosidase, an hydrolyzing β-1,6-fructosidic linkage, was immobilized covalently on the oxidized microbial cell wall of a Penicillium species (PS-8), which is totally different from the conventional whole cell immobilization. The microbial cells of the PS-8 strain, which has a fluffy characteristic during cultivation, was treated with sodium metaperiodate to form active aldehyde groups on them. The periodate treated cells were reacted with the β-fructofuranosidase. This mixture of cell and the enzyme was again treated with 0.5% glutaraldehyde for 1 hr and finally spinned with a syringe (diameter 1 mm) to form pellets, and dried at air. By determining the effects of periodate concentration on the aldehyde formation of microbial cells, the optimal treating concentration of periodate was 1.2 grams per gram of the dry weight and the formation of the aldehyde was 35% as the % dialdehyde units. The reaction temperature did not give any effect on the formation of aldehyde of the microbial ...
Supported gold nanoparticles are used for a wide range of catalytic processes. In this work, we use dispersion corrected density functional theory (DFT-D) to study the effect of commonly used support materials (MgO, C, CeO2) on small gold particles with up to 19 atoms. Our results show that the preferred cluster shape and morphology is highly dependent on the support material due to different adsorption strength and structural mismatch between the cluster and the surface material. We developed an algorithm to measure the mismatch between the cluster interface and the support surface. Moreover, depending on the support material, the gold clusters exhibit a positive or negative polarisation, which ultimately has strong implications on the catalytic activity of such particles. This behaviour is rationalised by an analysis of the electronic structure of the metal particles and support materials.. ...

The internal structure of aerobic granules has a significant impact on the hydrodynamic performance and mass transfer process, and severely affects the efficiency and stability of granules-based reactors for wastewater treatment. In this study, for the first time the granule complex structure was correlated with the hydrodynamic performance and substrates reactions process. First, a series of multiple fluorescence stained confocal laser scanning microscopy images of aerobic granules were obtained. Then, the form and structure of the entire granule was reconstructed. A three-dimensional computational fluid dynamics study was carried out for the hydrodynamic analysis. Two different models were developed on the basis of different fluorescence stained confocal laser scanning microscopy images to elucidate the roles of the granule structure in the hydrodynamic and mass transfer processes of aerobic granules. The fluid flow behavior, such as the velocity profiles, the pathlines and hence the ...

The biotransformation of water insoluble substrates by mammalian and bacterial cells has been problematic, since these whole cell reactions are primarily performed in an aqueous environment The implementation of a twophase or encapsulated system has the advantages of providing a low water system along with the physiological environment the cells require to sustain themselves. Encapsulation of mammalian cells by formation of polyamide capsules via interfacial polymerization illustrated that the cells could not survive this type of encapsulation process. Biotransformation of the steroid spironolactone [3] by human kidney carcinoma cells was performed in a substrate-encapsulated system, yielding canrenone [4] in 70% yield. Encapsulation of nitrile-metabolizing Rhodococcus rhodochrous cells using a polyamide membrane yielded leaky capsules, but biotransformation of 2-(4- chlorophenyl)-3-methylbutyronitrile (CPIN) [6] in a free cell system yielded CPIN amide [7] in 40% yield and 94% ee.

Mesenchymal stromal cells (MSCs) are nonhematopoietic multipotent cells displaying immunomodulatory, pro-angiogenic and reparative properties that were demonstrated both in animal and human models and has generated markedly increasing interest in a wide variety of biomedical disciplines. The International Society for Cellular Therapy (ISCT) proposed minimal criteria to define human MSCs: MSCs must be plastic-adherent, have a phenotype of CD105+, CD73+, CD90+, CD45-, CD34-, CD14-, HLA-DR-, and have the capacity to undergo in vitro differentiation to osteoblasts, adipocytes, and chondrocytes. We optimized techniques for isolation of MSCs from bone marrow and adipose tissue, their expansion in humanized serum-free culture system, cryopreservation, transport, quality control and potency testing and established protocol for their manufacturing in validated GMP aseptic conditions in Clean Rooms. It was necessary to establish humanized serum free cell culture system without risk of ineligible immune ...
E-cadherin interacts with other E-cadherin molecules on neighboring cells to form cell-cell adhesions. E-cadherin that is not involved in these trans interactions is removed from the cell surface and replaced with newly synthesized molecules to maintain dynamic adhesions. Now, Izumi et al. (page 237) show that E-cadherins that are involved in trans interactions are excused from this endocytosis by small GTPases. Disruption of this system may free cells for migration.. By reconstituting endocytosis in membrane bilayers, the group shows that clathrin-dependent endocytosis removes E-cadherin that is not interacting in trans with other E-cadherins. E-cadherins engaged in trans interactions, however, activated Rac and Cdc42, which blocked their internalization. So far it is unclear how the trans interactions activate the G proteins.. The endocytic block is enhanced by IQGAP1, an effector of Rac and Cdc42. IQGAP1 cross-links actin filaments into bundles, and the group shows that F-actin is needed to ...

By Greg Mills. As I write this Sunday morning early, all the Apple news sites and a lot of regular news sites are running leaked information about the iPhone launch, scheduled for Tuesday. The normally tight new product security has been breeched by even Apple in a couple of ways. What seems clear is that Apple is moving to capture greater market share with more cellular carriers to be offering iPhones and with both a lower end and higher end offering. The iPhone 4S and iPhone 5 appear to be the two new iPhone models to be announced Tuesday.. There are two main markets the cellular carriers all support. They call the two plans post-paid and pre-paid. Generally, the post-paid segment is the cream of the crop and the real money for the networks. This is the plan with a contract, generally for two years, where you get a red hot deal on a phone, or a free cell phone in exchange for signing up. With iPhones, you just pay a portion of the cost of the.... , Read more » ...

Industries which manufacture products or render services against specific orders as distinct from continuous production for stock or sales use the job costing or job order method of cost accounting. The method is also known under various other names, such as specific order costing, production order costing, job lot costing or lot costing. Every order in job costing is separate and it is not essential that the same manufacturing operations be carried out or the same materials be utilized in respect of each. However, a number of identical orders or identical products may be combined together to form lots or batches, each such lot or batch constituting a job order. In the job costing system, an order or a unit, lot, or batch of a product may be taken as a cost unit, i.e. a job. ...

In the early 1860s three Swedes, Nils Wilhelm Mitander,Julius Ramsay and Gustaf Wittenström, were engaged by theBritish to build and run charcoal-based ironworks in India.These works, the Burwai Iron Works of the British Government inthe case of Mitander and the privately owned Kumaon Iron Worksin the case of Ramsay and Wittenström, were both to bebased on the most modern European technology. The projects werepioneering in Indian ironmaking. The ambitions were high andstakes big, but after only a few years the projects were closedand the Swedes returned home.Landscapes of Technology Transferpresents a detailedstudy of the Kumaon and Burwai Iron Works, from their firstconception to their final closure. The investigation isbasically empirical and a fundamental question is: Why were theworks never brought into full and continuous production?.
