Facultative Anaerobic Bacteria from the Sheep's Rumen

Degradation of dehydrodivanillin by anaerobic bacteria from cow rumen fluid.

Dehydrodivanillin (DDV; 0.15 g/liter) was biodegradable at 37 degrees C under strictly anaerobic conditions by microflora from cow rumen fluid to the extent of 25% within 2 days in a yeast extract medium. The anaerobes were acclimated on DDV for 2 weeks, leading to DDV-degrading microflora with rates of degradation eight times higher than those initially. Dehydrodivanillic acid and vanillic aci...

Recovery of anaerobic, facultative, and aerobic bacteria from clinical specimens in three anaerobic transport systems.

With aspirated specimens from clinical infections, we evaluated the recovery of anaerobic, aerobic, and facultative bacteria in three widely used transport systems: (i) aspirated fluid in a gassed-out tube (FGT), (ii) swab in modified Cary and Blair transport medium (SCB), and (iii) swab in a gassed-out tube (SGT). Transport tubes were held at 25 degrees C and semiquantitatively sampled at 0, 2...

Isoleucine biosynthesis from 2-methylbutyric acid by anaerobic bacteria from the rumen.

Microorganisms in ruminal ingesta and pure cultures of anaerobic ruminal bacteria of different physiological and morphological groups incorporated (14)C from labeled 2-methylbutyrate during growth. The radioactivity was incorporated mainly into lipid and protein. Isoleucine was the only labeled amino acid found in acid hydrolysates of protein from either pure or mixed cultures. Radioactivity in...
