Seagren Civil and Environmental Engineering Department Assistant Professor, Jennifer G. Becker Environmental Science and Technology Department H2 thresholds have been widely used to demo...

BACKGROUND Acetate is a common microbial fermentative end-product, which can potentially be used as a supplementary carbon source to enhance the output of biotechnological production systems. This study focuses on the acetate metabolism of the photosynthetic cyanobacterium Synechocystis sp. PCC 6803 which is unable to grow on acetate as a sole carbon source but still can assimilate it via acety...

turnips with a long history of usage, are helpful in preventing breast and prostate cancer, inflammation and body`s immune system dysfunction. in this study, we investigated the effects of chloroform, ethyl acetate and methanolic extracts of brassica rapa l. on cell-mediated immune response in mice. chloroform, ethyl acetate and methanolic extracts of b. rapa glands were prepared by maceration ...

various extracts of sarcostemma viminale were screened for central analgesic activity by hot plate test, peripheral analgesic activity by acetic acid-induced writhings, cns depressant activity by pentobarbitone-induced sleep and locomotor activity testing methods and anthelmintic activity on the earthworms pheretima posthuma . results showed that petroleum ether and ethyl acetate extracts had g...

Chemical composition of propolis has been reported to be phyto-geographical in nature. The aim this study was isolate and characterize chemical compounds from hexane ethyl acetate extract obtained Gboko. To compounds, subjected column chromatography by gradient elution using two solvent mixtures - hexane: acetate: methanol. structure the isolated compound established 1H-NMR further verification...

the objective of this study was to evaluate the effect of dietary supplements with lead acetate and aluminosilicates (atn) on antioxidative enzyme activities and lipid peroxidation of the heart and skeletal muscle tissues of broiler chickens. broilers were allotted to four diets including the control group, the pb group, the aluminosilicate-atn (antitoxic nutrient) group and the pb+atn group, i...

An experimental approach for the production of catalyst-free hyperpolarised ethanol solution in water via heterogeneous hydrogenation of vinyl acetate with parahydrogen and the subsequent hydrolysis of ethyl acetate was demonstrated. For an efficient hydrogenation, liquid vinyl acetate was transferred to the gas phase by parahydrogen bubbling and almost completely converted to ethyl acetate wit...

The mechanism of acetate absorption in the small intestine is not yet established. One possible mechanism is by carrier mediated Na(+)-acetate cotransport since acetate, like glucose, stimulates intestinal Na+ and water absorption in vivo. Uptake of radioactive carbon acetate by small intestinal brush border membrane vesicles was not saturable or Na+ dependent and did not respond to osmotic shr...
