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...
متن کاملDegradation of protein by mixed cultures of rumen bacteria: identification of Streptococcus bovis as an actively proteolytic rumen bacterium.
Mixed cultures of rumen bacteria were inoculated into anaerobic buffer solutions containing mixed carbohydrates, casein and ammonia, and rates of bacterial growth, protein degradation, ammonia formation or utilization and lactate production were determined. Bacterial growth rate was varied by the provision of excess carbohydrate (one large dose at the onset of the incubation) or limited carbohy...
متن کاملRate of isolated hemicellulose degradation and utilization by pure cultures of rumen bacteria.
Rate studies on the utilization or degradation (or both) of isolated hemicelluloses were conducted with six strains of rumen cellulolytic bacteria. Utilization was estimated by total pentose loss, and degradation values were based on solubilization of the hemicellulose in acidified 80% ethyl alcohol. With the various strains of ruminococci, degradation of flax and fescue grass hemicellulose was...
متن کاملDegradation of starch granules by some amylolytic bacteria from the rumen of sheep.
pyrene and tran8-4,5-dihydro-4,5-dihydroxypyrene, were present in the bile of rats treated with pyrene. 3. In the oxidation of pyrene with perbenzoic acid an intermediate was formed, believed to be 4,5-epoxy-4,5-dihydropyrene, which reacted with water to yield tran8-4,5-dihydro-4,5-dihydroxypyrene and with N-acetyl-L-cysteine to form Nacetyl-S-(4,5-dihydro-4-hydroxy-5-pyrenyl)-L-CySteine. 1-Hyd...
متن کاملDegradation and Utilization of Isolated Hemicellulose by Pure Cultures of Cellulolytic Rumen Bacteria.
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...
