Disinfection of upper gastrointestinal fibreoptic endoscopy equipment: an evaluation of a cetrimide chlorhexidine solution and glutaraldehyde. (1/196)

There is little information available on the bacteriological contamination of upper gastrointestinal fibreoptic endoscopes during routine use and the effects of 'disinfecting solutions'. A bacteriological evaluation was therefore made of cleaning an endoscope and its ancillary equipment with (1) water, (2) an aqueous solution of 1% cetrimide with 0.1% chlorhexidine, and (3) activated aqueous 2% glutaraldehyde. All equipment, but particularly the endoscope itself, was found to be heavily contaminated after use with a wide variety of organisms of which 53% were Gram positive. Cleaning the endoscope and ancillary equipment with water and the cetrimide/chlorhexidine solution alone or in combination was inadequate to produce disinfection but immersion in glutaraldehyde for two minutes consistently produced sterile cultures with our sampling technique. A rapid and simple method for disinfection of endoscopic equipment is therefore recommended and we think this is especially suitable for busy endoscopy units.  (+info)

CTAB-mediated enrichment for active forms of novel dimeric maxizymes. (2/196)

We demonstrated previously that shortened forms of (stem II-deleted) hammerhead ribozymes with low intrinsic activity form very active dimers with a common stem II (very active short ribozymes capable of forming dimers were designated maxizymes). As a result of such a dimeric structure, heterodimeric maxizymes are potentially capable of cleaving a substrate at two different sites simultaneously. In this case, active heterodimers are in equilibrium with inactive homodimers. Longer forms of common stem II can lead to enrichment of the active heterodimers in vitro. In this study, we investigated whether the cationic detergent CTAB, which is known to enhance strand displacement of nucleic acids, might inhibit the dimerization of maxizymes. Significantly, under all conditions examined, CTAB instead enhanced the activity of a variety of maxizymes, with the extent of enhancement depending on the conditions. The activity of our least stable, least active maxizyme was enhanced 100-fold by CTAB. The strand displacement activity of CTAB thus appears to enhance the conversion of alternative conformations of inactive maxizymes, with intra- and inter-molecular hydrogen bonds, to active forms. Thus, our smallest maxizyme can also be considered a potential candidate for a gene-inactivating agent in vivo, in view of the fact that various facilitators of strand displacement reactions are known to exist in vivo (indeed, a separate experiment in cell culture supported the conclusion that our smallest maxizyme is a good gene-inactivating agent). Although activities of ribozymes in vitro do not necessarily reflect their activities in vivo, our findings suggest that the activity of ribozymes in vivo can be better estimated by running ribozyme kinetics in the presence of CTAB in vitro.  (+info)

Optimised sample preparation of synovial fluid for detection of Chlamydia trachomatis DNA by polymerase chain reaction. (3/196)

OBJECTIVE: To optimise sample preparation of synovial fluid for Chlamydia trachomatis (CT) specific polymerase chain reaction (PCR). METHODS: Serial dilutions of purified CT elementary bodies in synovial fluid were prepared. The synovial fluid pellet was processed by eight different methods of sample preparation. Then samples were analysed by CT specific PCR. The sensitivity of PCR was the basis of ranking of the eight different methods. RESULTS: Highest sensitivity was achieved by methods including an additional step of DNA isolation. Additional extraction of protein and polysaccharides by cetyltrimethylammonium bromide (CTAB) increased sensitivity. Addition of hyaluronidase did not increase sensitivity of QIAEX-DNA extraction but was necessary, however, before phenol-chloroform-DNA extraction. CONCLUSIONS: The method of synovial fluid sample preparation significantly influences the sensitivity of subsequent PCR. Additional DNA isolation and extraction of PCR inhibitors by CTAB led to higher sensitivity.  (+info)

DNA conformational dynamics in the presence of catanionic mixtures. (4/196)

DNA conformational behavior in the presence of non-stoichiometric mixtures of two oppositely charged surfactants, cetyltrimethylammonium bromide and sodium octyl sulfate, was directly visualized in an aqueous solution with the use of a fluorescence microscopy technique. It was found that in the presence of cationic-rich catanionic mixtures, DNA molecules exhibit a conformational transition from elongated coil to compact globule states. Moreover, if the catanionic mixtures form positively charged vesicles, DNA is adsorbed onto the surface of the vesicles in a collapsed globular form. When anionic-rich catanionic mixtures are present in the solution, no change in the DNA conformational behavior was detected. Cryogenic transmission electron microscopy, as well as measurements of translational diffusion coefficients of individual DNA chains, supported our optical microscopy observations.  (+info)

Escherichia coli TEM1 beta-lactamase in CTAB reverse micelles: exchange/diffusion-limited catalysis. (5/196)

We report kinetic data of penicillin hydrolysis catalyzed by beta-lactamase entrapped in reverse micelles formed with cetyl trimethylammonium bromide (CTAB), n-octane, hexanol and aqueous buffer. The K(cat) of this diffusion-limited reaction can be improved in aqueous buffer by a factor of 1.1-1.2 just by increasing the phosphate buffer concentration from 50 to 100 mM. In reverse micelles, increasing the buffer concentration has little effect on K(cat) when the size of the empty micelle is below the size of the protein. However, in larger micelles, the effect is enhanced and the K(cat) improves several fold, changing the form of the curve of K(cat) versus Wo from bell-shaped to almost hyperbolic. The results indicate that micellar exchange and internal diffusion may limit the reaction in reverse micelles and provide further evidence that the form of the curve depends on other factors besides the relationship between the size of the enzyme and that of the empty reverse micelle.  (+info)

Models for enzyme superactivity in aqueous solutions of surfactants. (6/196)

Theoretical models are developed here for enzymic activity in the presence of direct micellar aggregates. An approach similar to that of Bru et al. [Bru, Sanchez-Ferrer and Garcia-Carmona (1989) Biochem. J. 259, 355-361] for reverse micelles has been adopted. The system is considered to consist of three pseudo-phases: free water, bound water and surfactant tails. The substrate concentration in each pseudo-phase is related to the total substrate concentration in the reaction medium. In the absence of interactions between the enzyme and the micelles, the model predicts either monotonically increasing or monotonically decreasing trends in the calculated reaction rate as a function of surfactant concentration. With enzyme-micelle interactions included in the formulation (by introducing an equilibrium relation between the enzyme confined in the free water and in the bound water pseudo-phases, and by allowing for different catalytic behaviours for the two forms), the calculated reaction rate can exhibit a bell-shaped dependence on surfactant concentration. The effect of the partition of enzyme and substrate is described, as is that of enzyme efficiency in the various pseudo-phases.  (+info)

Second harmonic generation of glucose oxidase at the air/water interface. (7/196)

We present a study of the adsorption of the glucose oxidase enzyme (GOx) at the air/water interface, using the nonlinear optical technique of surface second harmonic generation (SSHG). Resonant SSHG experiments were achieved by probing the pi-pi* transition of the flavin adenine dinucleotide (FAD) chromophores embedded in the GOx protein. Because of the subsequent resonance enhancement of the signal, the second harmonic (SH) wave arising from the GOx entities adsorbed at the interface was detectable for protein bulk aqueous concentrations as low as 70 nM. The protein adsorption was followed, and, at high GOx coverage, a change in the orientation of the FAD chromophore was observed, indicating either a rearrangement or a reorientation of the protein at the interface. Inasmuch as GOx is negatively charged at the biological pH of 7, its interactions with charged surfactants were also investigated. As expected, spreading positively charged surfactants onto a partial protein monolayer was found to increase the GOx surface concentration, whereas in the case of negatively charged surfactants, the GOx surface concentration decreased until the SH signal went back to the pure buffer solution response level. With the increasing GOx surface concentration, the rearrangement or reorientation of the protein was also observed.  (+info)

A method for preparing genomic DNA that restrains branch migration of Holliday junctions. (8/196)

The Holliday junction is a central intermediate in genetic recombination. This four-stranded DNA structure is capable of spontaneous branch migration, and is lost during standard DNA extraction protocols. In order to isolate and characterize recombination intermediates that contain Holliday junctions, we have developed a rapid protocol that restrains branch migration of four-way DNA junctions. The cationic detergent hex-adecyltrimethylammonium bromide is used to lyse cells and precipitate DNA. Manipulations are performed in the presence of the cations hexamine cobalt(III) or magnesium, which stabilize Holliday junctions in a stacked-X configuration that branch migrates very slowly. This protocol was evaluated using a sensitive assay for spontaneous branch migration, and was shown to preserve both artificial Holliday junctions and meiotic recombination intermediates containing four-way junctions.  (+info)

A new potentiometric anionic surfactant sensor was prepared based on multi-walled carbon nanotubes (MWCNTs) used for immobilisation of 1,3-didecyl-2-methylimidazolium tetraphenylborate (DMI-TPB) ion pair as ionophore in the membrane. The investigated sensor showed a Nernstian response for both dodecylbenzenesulphonate and dodecyl sulphate. It responded in 8-10 seconds for each ten-fold concentration change in the range of 1 x 10-7 M to 1 x 10-3 M. The detection limits for DBS and DS were 1 x 10-6 and 2 x 10-7 M, respectively. The sensor revealed a stable potentiometric response and exhibited satisfactory selectivity for DS. The main application of the sensor was in the end-point detection in potentiometric titrations of anionic surfactants. Hyamine 1622, hexadecyltrimethylammonium bromide and cetylpyridinium chloride were tested as potential cationic titrants, and all exhibited analytically usable titration curves with well-defined equivalence point.

An experiment was done to determine the ability to fabricate carbon aerogel electrodes for use in a phosphoric acid fuel cell (PAFC). It was found that the use of a 25% solution of the surfactant Cetyltrimethylammonium chloride (CTAC) in water resulted in the creation of micelle within the pores of the organic aerogel. The micelle allowed the aerogel to be air dried while maintaining the desired pore composition. Further testing also showed that the resulting carbon aerogels had a specific ionic conductivity greater than that of a commercial porous carbon electrode Work was done to explore the use of the DRIE method to create a silicone die for the fabrication of a carbon aerogel electrode. It was found that a die could be created but had to undergo 0₂ plasma treatment in order to improve the wetting properties of the die. The resulting electrode was found to be very brittle at a thickness of 200 [mu]m or less, but responded well to being electroplated with platinum through the use of a ...

An original, sensitive, and specific high-performance liquid chromatographic (HPLC) assay was developed for the quantitation of morphine and its two major metabolites, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G), in human plasma and cerebrospinal fluid (CSF) and in rat plasma, using hydromorphone as the internal standard. Solid-phase extraction was used to separate morphine and its glucuronide metabolites from plasma constituents. Extraction efficiencies of morphine, M3G, and M6G from human plasma samples (0.5 ml) were 84, 87, and 88%, respectively. Extraction efficiencies of morphine, M3G, and M6G did not differ significantly (p > 0.05) between human plasma and CSF or rat plasma. Morphine, M3G, M6G, and hydromorphone were separated on a 10 mu C-8 Resolve radially compressed cartridge using a mobile phase comprising methanol:acetonitrile:phosphate buffer, (0.0125M pH 7.5; 10: 10:80), in which 11 mg/L of cetyltrimethylammonium bromide (cetrimide) was dissolved.

Authors: MUHAMMAD AKHYAR FARRUKH, HENG BOON TECK, ROHANA ADNAN Abstract: Tin oxide nanoplates and nanoballs were fabricated using a cationic surfactant of cetyltrimethylammonium bromide (CTABr) as an organic supramolecular template and tin(IV) chloride as an inorganic precursor via the hydrothermal and conventional heating methods. Urea, which decomposes to ammonium and hydroxide ions during hydrolysis, was used as the source of slow homogeneous precipitation of Sn^{4+} with OH^- to control the particle size. The influence of different reaction parameters (time, temperature, and ratio of Sn^{4+} to CTABr) on particle sizes, particle distribution, and morphology was investigated using X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectroscopy. XRD data showed that the size of the SnO_2 nanoparticles decreased with increasing reaction time using the conventional heating method, while no significant change was observed with the hydrothermal ...
Phosphorus (P) availability in soil is abysmally low due to its high reactivity with soil constituents. Use of nanoclay-polymer composites (NCPCs) as a fertilizer carrier is the new avenue of research in the field of agriculture due to their role in controlled release of nutrients synchronizing with crop demand. A series of NCPCs were prepared using nano-bentonite and modified nanobentonite with varying neutralization degree and cross linker level. Phosphorus was loaded as diammonium phosphate (DAP) after polymerization of NCPCs. Bentonites as well as NCPCs were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). The XRD patterns confirmed an increase in interlayer spacing from 13.0Å in nano-bentonite to 19.2Å in modified nanobentonite (treated with cetyl trimethyl ammonium bromide). Disappearance of -OH stretching vibration of clays and weakening of Si-O stretching vibration in ...
The effect of three synthetic surfactants on surface activity and surface dilatational rheology of temperature-denatured type I collagen at water/air interface is described. An anionic (sodium dodecyl sulfate, SDS), a cationic (cetyltrimethylammonium bromide, CTAB) and a nonionic (Triton X-100, TX-100) surfactants were employed at variable concentrations (5 × 10−6 mol L−1-1 × 10−4 mol L−1). With the protein concentration fixed at 5 × 10−6 mol L−1, the protein/surfactant mixtures with molar ratios of 1:1, 1:2, 1:3, 1:5, 1:10 and 1:20 were obtained. An Axisymmetric Drop Shape Analysis (ADSA) method was used to determine the dynamic and equilibrium surface tension, as well as the surface dilatational moduli of the mixed adsorption layers formed at the water/air interface at pH 4.5. For the collagen-SDS mixtures, analogous studies were also performed at the water/tetradecane and water/olive oil interfaces. These results were complemented with the foam and emulsion formation ability tests, and

Frog sciatic nerves were excised and treated in a Ringers solution containing the surface-active agent, cetyltrimethylammonium bromide (CTMB). Such CTMB-treated nerves were compared to normal, untreated nerves with respect to their susceptibility to conduction block produced by six lipid-insoluble quaternary ammonium ions; the CTMB-treated nerves were rendered especially susceptible to rapid, reversible conduction block. A possible mechanism of CTMB action is proposed, involving chemo-dissection of permeability barriers which normally surround the individual axons. The findings that acetylcholine, curare, etc. can produce reversible, axonal conduction block in CTMB-treated nerves are not inconsistent with a theory of cholinergic impulse conduction.. ...
Micelles of cetyltrimethylammonium bromide catalyse the alkaline hydrolysis of benzylpenicillin with a rate enhancement of ca. 50-fold. However, the rate of reaction is inhibited by increasing concentrations of hydroxide ion and penicillin anion. A saturation phenomenon is observed with increased concentration of surfactant. Attempts are made to determine the binding- and rate-constants using existing kinetic models. These are not completely satisfactory and a model is proposed which assumes that both hydroxide ion and penicillin have to be bound to the micelle for reaction to occur. Bromide, chloride, acetate, fluoride, and benzylpenicilloate ions all inhibit the micellar catalysis.. ...
Noble metal mesoscale and nanoscale materials exhibit unique optical properties that are of interest to a wide variety of fields including sensing, imaging, biomedicine, and catalysis. The properties of the nanomaterial are strongly dependent on the size, morphology, composition, and local molecular environment of the material, all of which can be controlled by material design and synthesis. A novel nanomaterial referred to as a gold nanobelt was synthesized and characterized. Gold nanobelts synthesized in cetyltrimethylammonium bromide and sodium dodecylsulfate and with sub-100 nm rectangular cross sections were found to exhibit a strong transverse plasmon peak at visible wavelengths. Unlike larger diameter silver nanowires, these nanobelts exhibit sharp, tunable plasmon resonances similar to those of nanoparticles. The gold nanobelt crystal structure contains a mixture of face centered cubic and hexagonally close packed lattice phases that can be isolated and examined individually due to the ...
In the present work a capillary electrophoretic method for the analysis of monosaccharides utilizing indirect UV-detection has been developed.

Furthermore, a curve-fitting algorithm has been introduced to increase the separation resolution. The optimized method has been used for analysis of monosaccharides from an acidically hydrolyzed pulp sample.. ...
The strong UV absorption of the bromide in aqueous solution undergoes a remarkable red shift of more than 10 nm induced by the addition of the salts that constitute a saline buffer. The maximum absorption wavelength of the bromide is displaced from approximately 194 nm in ultrapure water to wavelengths above 200 nm, depending on the composition of the solution. The bromide

When DNA is mixed with CTAB we found, with increasing surfactant concentration, (1) free DNA coexisting with surfactant unimers, (2) free DNA coexisting with aggregates of condensed DNA and CTAB, (3) a miscibility gap where macroscopic phase separation is observed, and (4) positively overcharged aggregates of condensed DNA and CTAB. The presence of a clear solution beyond the miscibility gap cannot be ascribed to self-screening by the charges from the DNA and/or the surfactant; instead, hydrophobic interactions among the surfactants are instrumental for the observed behavior. It is difficult to judge whether the overcharged mixed aggregates represent an ...

Aqueous phase behavior and structures of phases were studied in systems containing sodium poly(styrenesulfonate), NaPSS, and complex salt CTAPSS, formed between cetyltrimethylammonium cations, CTA(+), and PSS- anions. It was shown that hydrophobic interaction of the polyion styrene groups with surfactant aggregates, which supports the strong electrostatic attraction between CTA(+) and PSS-, has a significant effect on phase behavior and structures. Only the disordered micellar (L-1) and the ordered hexagonal (H-1) phase were found that are connected over a broad two-phase region of L-1-H-1 coexistence. At water contents above 60 wt%, CTAPSS is easily dissolved in proportion to the amount of added NaPSS, whereas at lower water contents a large excess of NaPSS is needed to dissolve CTAPSS. Phase separation in the two-phase region is controlled by two tendencies: (i) to maximize the contact between the hydrophobic groups and micelles (assisted by hydrophobic interaction) and (ii) to form as dense ...

Cetyl Myristoleate is a naturally occurring fatty acid, found most frequently in fish oils and butter. It was discovered first in albino mice, which are immune to arthritis. Cetyl M was found to be the reason why. Cows, beavers and sperm whales are also thought to produce Cetyl M naturally. Scientists have recently found a way to synthesize this acid and have used it in treating humans, dogs and even horses. Cetyl M has anti-inflammatory properties, reducing the symptoms of even the most severe arthritis, though it is thought to be most effective when given early in the diseases development process. It can also be used to relieve symptoms of joint disease, such as hip dysplasia. No one has been able to determine why Cetyl M works, but some scientists suggest that it is able to reprogram faulty cells that cause the arthritis. No matter what the reason, Cetyl M seems to be very helpful in reducing symptoms of arthritis in animals. Many owners proclaim miraculous recoveries in their pets. There ...

Nacre-like structures have attracted great interest in recent years due to their outstanding toughness, stiffness and impact resistance. However, there is a challenge associated with engineering nacre-like calcium phosphate crystals. In this study, thin nacreous-like monetite sheets were synthesized in solutions guided by a surfactant. The influence of temperature, initial pH, Ca/P ratio, stirring time and the concentration of cetyltrimethylammonium bromide (CTAB) on the nacre-like structure has been studied. Findings showed that a nacre-like structure could only be formed at a high temperature (90 °C), high initial pH (11), sufficient stirring time (3 h), and under the presence of CTAB. A small-angle X-ray scattering experiment carried out at a synchrotron radiation facility showed that the distance between nanolayers was around 2.6 nm and TEM confirmed the fine sheet-like structure. The mechanism of the formation the nacre-like structure and its characterization were discussed.. ...
This paper describes our recent work in which CTAB (cetyltrimethylammonium bromide) micelles are used as catalytic platforms for performing bromination and oxidation reactions in water. The bromide counter ion is used to prepare Br2 in situ which is subsequently employed as a brominating and oxidizing agent. In this process the bromide is rapidly oxidized to bromine using BPO (benzoic peroxyanhydride). The reaction is facilitated by the micelle which improves the BPO solubility and its proximity with Br-. Several example reactions are discussed including micelle-assisted bromination of cholesterol and methyl styrene along with an example of mild oxidation of benzyl alcohol to form benzaldehyde. These examples illustrate the use of bromine as a mild oxidizing agent and also as a brominating agent. Kinetic studies of Br2 formation and cholesterol bromination are also presented ...
White spot syndrome associated baculovirus (WSBV) is the causative agent of a disease which has recently caused high shrimp mortalities and severe damage to shrimp cultures. In this study, a strain of WSBV from black tiger shrimp Penaeus monodon was used to develop a diagnostic tool for the detection of WSBV and related agent infections in shrimp. The virions were purified from P. monodon infected with WSBV. Viral genomic DNA was extracted from purified virions by treating the virions with proteinase K and cetyltrimethylammonium bromide (CTAB) followed by phenol-chloroform extraction and ethanol precipitation. A qualitative assessment was performed using polymerase chain reaction (PCR) analysis on the viral DNA and primers specific to shrimp genomic DNA in order to monitor shrimp DNA contamination in the viral genomic DNA preparations. A WSBV genomic DNA library was constructed and, based upon the sequence of the cloned WSBV DNA fragment, we designed a WSBV-specific primer set for PCR to detect ...

en] The Km, app. values of the membrane-bound transpeptidase of Streptomyces R61 for the donor Ac2-L-Lys-D-Ala-D-Ala and the acceptor Gly-Gly are not affected by temperature variations when the reaction mixtures are incubated in liquid suspensions. At -5 degrees C, the incubation can be carried out either in the liquid or in the frozen state. The enzyme is active in the latter state. In the frozen state, the Km, app. value for the acceptor remains unchanged but there is a 3-fold increase in the maximum velocity, a 10-fold decrease of the Km, app. value for the donor and a 10-fold increase of the benzylpenicillin concentration required to inhibit the enzyme activity by 50% (ID50 value). Temperatures of -35 degrees C or below are required to completely inhibit the membrane-bound enzyme in the frozen state. Cetyltrimethylammonium bromide extracts the transpeptidase both from the isolated membranes and, with a much higher yield, from the intact mycelium. The extracted enzyme is not active in the ...

The determination of salicylic, p-aminosalicylic and 5-fluorosalicylic acids was investigated using terbium-sensitized luminescence in aqueous solutions. Formation of a ternary chelate between terbium, EDTA and the salicylic acid requires dissociation of the phenol group which is adjacent to the dissociated carboxylic group. The reaction is obtained in alkaline solutions and is enhanced in the presence of cetyltrimethylammonium chloride. As evidenced by absorbance and fluorescence measurements, the cationic surfactant plays an important role in the formation of the ternary chelate and then terbium luminescence depends mainly on the extent of chelate formation. Linearity is found over more than four orders of magnitude and detection limits are in the range (2-4) x 10(-10) mol l-1 for the three acids.
Members of the Pseudomonas family are commonly found in nature, some species are pathogenic for humans, as well as being resistant to multiple disinfectants. Various studies have revealed that benzalkonium chloride (BKC) has an inhibitory effect on many bacteria but it has no significant effect on Pseudomonas aeruginosa. Cetrimide agar medium is recommended for the isolation and enumeration of Ps. aeruginosa in food and environmental samples. However, there are claims that for some food factories and in particular the bottled water industry, the selectivity of this medium is not sufficient. The aim of the current research is the creation of a more selective medium for Ps. aeruginosa with BKC. A total of 28 isolates were isolated with Cetrimide agar from raw water samples and identified using biochemical tests and commercial identification kits. All the bacteria were inoculated in Cetrimide agar plates containing 0 - 625 μg/mL BKC. The Petri dishes were incubated at 37°C and 42°C for 24 h. The results

Dear molbio.methds-reagnts readers, Our lab has successfully amplified the ITS1 and ITS2 rDNA region in the group of algae we are studying using DNA from a quick and dirty CTAB prep as the template. I am now attempting to modify our protocol to amplify the region using a single colony of algae dropped into the reaction mix as our template. In my first attempt I had no amplification at all. I extended the number of cycles and the extension time and got a very weak, fuzzy band from one of my tubes. (My control was negative). Im going to continue to play with this, but I thought Id throw it out onto the net to see if anyone had any suggestions. Basically I need to get stronger amplification and a sharper band. Have any of you had success in optimizing a PCR protocol like this? Anyone have any tips for amplifying from a single colony (about 10-70 eukaryotic cells)? Even though our target DNA is present in multiple copies in the genome, Im concerned that there might be too little DNA there to ...

Using an in vivo test on teat skin the disinfectant activity of a teat dip containing chlorhexidine and cetrimide was compared with two iodophor solutions, one containing the recommended concentration of 0.5 per cent available iodine and the other a 10-fold dilution of this (0.05 per cent iodine). The test organisms used were Staphylococcus aureus and Escherichia coli and for both species the 0.5 per cent iodophor was significantly more bactericidal than either the diluted iodophor or the chlorhexidine/cetrimide teat dip (P less than 0.01). In the test against S aureus, chlorhexidine/cetrimide and the 0.05 per cent iodophor showed similar bactericidal activity, but the iodophor was significantly more bactericidal against E coli (P less than 0.01). It is argued that due to its low bactericidal activity this formulation of chlorhexidine/cetrimide is likely to be inferior to 0.5 per cent iodophor solution as a disinfectant teat dip.. ...

Surfactants such as cetyltrimethylammonium (CTA+) and cetylpyridinium (CP+) have diverse applications in various biological and industrial processes. In this dissertation, these surfactants with bromide counterions have been used to produce bromine in situ by the oxidation of the bromide anions using benzoyl peroxide (BPO) as the oxidizing agent in water (Chapter 2). The method presented here is safe and cost effective compared to other conventional methods that use metal catalysts or organic solvents for bromine generation. As an illustration, in situ generated bromine has been employed as a brominating agent for cholesterol and methyl styrene; and as an oxidizing agent for benzyl alcohol and 1,4-bis(hydroxymethyl)benzene. The partial oxidation of the aromatic alcohols form aldehydes and is significant since the typical oxidation product of primary alcohols in water is their corresponding acid. However, the partial oxidation of 1,4-bis(hydroxymethyl)benzene in CPB micelle gives a regioselective ...

Nonionic surfactants are surface active agents which do not dissociate into ions in aqueous solutions, unlike anionic surfactants which have a negative charge and cationic surfactants which have a positive charge in aqueous solution. Nonionic surfactants are more widely used as detergents than ionic surfactants because anionic surfactants are insoluble in many hard water and cationic surfactants are considered to be poor cleaners. In addition to detergency, nonionic surfactants show excellent solvency, low foam properties and chemical stability. It is thought that nonionic surfactants are mild on the skin even at high loadings and long-term exposure. The hydrophilic group of nonionic surfactants is a polymerized alkene oxide (water soluble polyether with 10 to 100 units length typically). They are prepared by polymerization of ethylene oxide, propylene oxide, and butylene oxide in the same molecule. Depending on the ratio and order of oxide addition, together with the number of carbon atoms ...

Bacteriorhodopsin (bR), the most widely studied membrane protein, consists of seven transmembrane helical segments and functions which can work as a proton pump in Halobacterium Salinarium. In the present study, the reversible control of bR conformation with simple light illumination is examined, providing a protocol to probe membrane protein folding (a challenge even to this day due to the large, aggregation-prone hydrophobic regions of membrane proteins compared to soluble proteins). Two general methodologies are utilized to control membrane protein folding, including (1) saturation of the natural lipids with a photoresponsive surfactant resulting in partitioning of the protein into detergent-lipid mixed micelles in the unfolded state, and (2) the development of artificial bilayers ...

For example, the anionic detergent sodium dodecyl sulfate (SDS) carries a negatively charged sulfate group on a linear C12 hydrocarbon chain. SDS is considered as a very strong and biologically harsh surfactant. It is able to denature proteins by breaking intra- and intermolecular interactions and thus destroying their biological activity. Other anionic detergents like the bile acid salts Na-cholate and Na-deoxycholate have a rigid steroidal core structure. They do not carry a well defined polar head group opposite to a hydrophobic tail (such as SDS). The polar groups are distributed on different parts of the molecule, resulting in a polar and non-polar side, e.g. Na-deoxycholate carries a carboxylate group at the end of a short hydrocarbon chain and two hydroxyl groups on the steroid structure. The bile acids are less denaturing than the ionic alkyl detergents, possibly due to their rigid steroidal ring structure.. Cationic detergents have a positively charged head group, which is often a ...

Wax esters are long-chain esters that have been widely applied in premium lubricants, parting agents, antifoaming agents and cosmetics. In this study, the biocatalytic preparation of a specific wax ester, cetyl octanoate, is performed in n-hexane using two commercial immobilized lipases, i.e., Lipozyme® RMIM (Rhizomucor miehei) and Novozym® 435 (Candida antarctica). Response surface methodology (RSM) and 5-level-4-factor central composite rotatable design (CCRD) are employed to evaluate the effects of reaction time (1-5 h), reaction temperature (45-65 °C), substrate molar ratio (1-3:1), and enzyme amount (10%-50%) on the yield of cetyl octanoate. Using RSM to optimize the reaction, the maximum yields reached 94% and 98% using Lipozyme® RMIM and Novozym® 435, respectively. The optimum conditions for synthesis of cetyl octanoate by both lipases are established and compared. Novozym® 435 proves to be a more efficient biocatalyst than Lipozyme® RMIM.
