Starr, Patricia R. (Oregon State University, Corvallis) and L. W. Parks. Some factors affecting sterol formation in Saccharomyces cerevisiae. J. Bacteriol. 83:1042-1046. 1962.-A wild-type diploid strain of Saccharomyces cerevisiae was used in a study of factors that influence sterol synthesis. Maltose, glucose, sodium acetate, and ethanol were shown to be readily available for sterol synthesis ...

The marine alga Isochrysis galbana was grown under the integrated influence of nitrogen starvation and sodium acetate, specifically to understand associated remodelling fatty acid profiles. This is first comparative proteomics study four different set conditions namely nutrient sufficient, with/without acetate N-deficient acetate. A total 546 unique peptides were detected. Due addition 56 prote...

conclusions the results of this study showed that exposure to lead increased the activity of g6pd in the rat erythrocytes, perhaps resulting in an up regulation of the enzyme to detoxify lead. materials and methods in this study 14 albino rats were divided into two groups of seven animals. the treated group was exposed to 2% lead acetate in the drinking water during eight weeks. the control gro...

The first branch point in gluconeogenesis occurs at the conversion of pyruvate to oxaloacetate. To determine the amount of lactate carbon reaching glucose via the direct pyruvate carboxylase pathway versus the tricarboxylic acid cycle, adult rat hepatocytes in primary culture were incubated for 2 h with one of the following isotopic substrates: [1-14C]lactate, [U-14C]lactate, or [1,2-14C]acetat...

Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...

The acs1 knockout mutant that has a disruption in the plastidic acetyl-coenzyme A (CoA) synthetase (ACS; At5g36880) gene was used to explore the role of this protein and plastidic acetate metabolism in Arabidopsis (Arabidopsis thaliana). Disruption of the ACS gene decreased ACS activity by 90% and largely blocked the incorporation of exogenous (14)C-acetate and (14)C-ethanol into fatty acids. W...

Entamoeba histolytica, an amitochondriate protozoan parasite that relies on glycolysis as a key pathway for ATP generation, has developed a unique extended PPi-dependent glycolytic pathway in which ADP-forming acetyl-coenzyme A (CoA) synthetase (ACD; acetate:CoA ligase [ADP-forming]; EC 6.2.1.13) converts acetyl-CoA to acetate to produce additional ATP and recycle CoA. We characterized the reco...

The production of valuable biological products from sugars via fermentation is of importance in the chemical industry. One key parameter by which processes are evaluated is the product carbon yield on substrate. In the normal growth of heterotrophic organisms on fermentable sugars, some carbon is lost as CO2. In the production of acetate from hexose or pentose sugars, homoacetogens using the re...
