The aim of this study was to investigate the chemical composition three maca (Lepidium meyenii Walp.) ecotypes (yellow, black, and red) their in vitro fermentation characteristics antioxidant effects on cow rumen liquor. were added a total mixed ratio (TMR) different doses (0, 150, 300 mg/g) incubated under anaerobic conditions for 120 h. Methane production recorded after 24 h incubation. Antio...

Abstract. Agustina S, Wiryawan KG, Suharti Meryandini A. 2021. The enrichment process and morphological identification of anaerobic fungi isolated from buffalo rumen. Biodiversitas 23: 469-477. Anaerobic are one the microbes that have an important role in rumen fiber degradation because they can produce cellulase enzymes penetrate feed particles. Nevertheless, few studies were performed to test...

Previous work by this laboratory (Roth et al., 1955) has established that a definite aeration requirement existed for spore formation of Bacilus anthracis and Bacillu globigii. This aeration requirement was shown to be different at various stages of growth. In the case of spore germination of the aerobic organisms tested, the present work indicates that the necessity for aerobic conditions is c...

methyl tertiary butyl ether (mtbe) belongs to the group of gasoline oxygenates and persistent environment contaminants, and shows potential for biodegradation in aerobic and anaerobic conditions, through application of pure microbial cultures. presented research shows that indigenous bacterial isolates 6sy and 24p, selected from oil hydrocarbons-contaminated environments, were capable of utiliz...

1. Tetrodotoxin, at concentrations at which it abolishes generation of action potentials in the nervous system, enhances by about 300% the rate of anaerobic glycolysis of brain-cortex slices from adult rats, or from adult and infant guinea pigs. This occurs to a greater extent in Ca(2+)-deficient incubation media than in Ca(2+)-rich media. Tetrodotoxin has no accelerative effect on cerebral aer...

Tetrabromobisphenol A (TBBPA) is a flame retardant that is used as an additive during manufacturing of plastic polymers and electronic circuit boards. Little is known about the fate of this compound in the environment. In the current study we investigated biodegradation of TBBPA, as well as 2,4,6-tribromophenol (TBP), in slurry of anaerobic sediment from a wet ephemeral desert stream bed contam...
