Mycelial and yeast-phase culture filtrates prepared from three strains of Paracoccidioides brasiliensis exhibited equal reactivity in sensitized guinea pigs. Ethyl alcohol-precipitated fractions obtained from the culture filtrates also showed no difference in reactivity between mycelial and yeast phase when tested in sensitized guinea pigs. Chemical analyses of the ethyl alcohol-precipitated fr...

Dehority, B. A. (Ohio Agricultural Experiment Station, Wooster). Degradation and utilization of isolated hemicellulose by pure cultures of cellulolytic rumen bacteria. J. Bacteriol. 89:1515-1520. 1965.-Hemicelluloses isolated from flax, corn hulls, alfalfa, oat hulls, and fescue grass were used as sole energy sources to study the ability of pure cultures of cellulolytic rumen bacteria to degrad...

SUMMARY Iris cyst occurs post intraocular -surgery or post penetrating trauma, when corneal epithelial cells or conjunctiva} epithcells gains access to the anterior chamber, with cells may continue to grow & covering all available surface and formed iris cyst. As the cyst grow may caused glaucoma or block pupil area & leads to vision treatment of all form of iris cyst and epithelial down growt...

People tend to equate the in vitro alcohol oxidation (via aldehyde to acid) with what happens in the animal body. However, the chemical experience shows, that the nature of the intermediate(s) and the yield of end product(s) varies with the organism studied. The animal has a peculiar oxidation ability: some substances are oxidized almost completely whereas for others the oxidation might be rest...

AIMS Some European countries with high levels of unrecorded alcohol consumption have anomalously high rates of death attributable to liver cirrhosis. Hepatotoxic compounds in illegally produced spirits may be partly responsible. Based on a review of the evidence on the chemical composition and potential harm from unrecorded alcohol, the Alcohol Measures for Public Health Research Alliance (AMPH...

The classes and concentrations of volatile organic compounds (VOC) released from fresh and decaying strawberries were investigated and compared. In this study, a total of 147 strawberry volatiles were quantified before and after nine days of storage to explore differences in the aroma profile between fresh strawberries (storage days (SRD) of 0, 1, and 3) and those that had started to decay (SRD...

Kinetics of lipase-catalyzed esterification of hexanoic acid and ethyl alcohol using the solvent-free system, surface coated lipase from Candida rugosa, had been studied. The effect of various parameters such as reaction time, reaction temperature, reaction kinetics, water removal and feasibility of solvent-free system had been focused. Candida Rugosa lipase was more effective than other li...

Abstract The fine chemical and pharmaceutical industries use large amounts of various organic solvents in their manufacturing processes. By reusing them, production costs can be significantly reduced. If we regenerate waste solvent mixtures, have the opportunity to reuse them process or other Our study illustrates an efficient regeneration using example a four-component mixture. Calculations we...

Volatiles are frequently abused as inhalants. The methods used for identification are generally nonspecific if analyzed concurrently with ethanol or require an additional analytical procedure that employs mass spectrometry. A previously published technique utilizing a capillary flow technology splitter to simultaneously quantitate and confirm ethyl alcohol by flame ionization and mass spectrome...
