Sensitivity of Ruminal Microorganisms to Pentachlorophenolt
Pentachlorophenol (PCP) is used extensively as a biocidal agent, and there is considerable concern about the adverse effects of this compound in biological ecosystems. The effects of PCP on the growth and fermentative activity of cultures of mixed ruminal microorganisms and the sensitivity of 14 ruminal bacterial species to PCP in pure culture were examined in this study. Increasing concentrati...
متن کاملAnalysis of peptide metabolism by ruminal microorganisms.
Methods were developed for the determination of oligoalanine and other short-chain peptides and peptide analogs in ruminal fluid by using reverse-phase high-pressure liquid chromatography. Chromatographic analysis of the breakdown of (Ala)3 and (Ala)4 in ruminal fluid in vitro revealed that the predominant mechanism of hydrolysis was a dipeptidyl peptidase-like activity. Hydrolysis proceeded fr...
متن کاملProteolytic activity of the ruminal bacterium Butyrivibrio fibrisolvens.
The proteolytic activity of Butyrivibrio fibrisolvens, a ubiquitously distributed bacterial species in the gastrointestinal tracts of ruminants and other mammals, was characterized. The relative proteolytic activity (micrograms of azocasein degraded per hour per milligram of protein) varied greatly with the strain: 0 to 1 for strains D1, D16f, E21C, and X6C61; 7 to 15 for strains IL631, NOR37, ...

متن کاملEnhanced degradation of 3-nitropropanol by ruminal microorganisms.
Ruminal fluid was obtained over a 4-yr period from cattle on various diets and supplements to determine the effects of different inocula on the microbial degradation of 3-nitropropanol (NPOH), a toxic metabolite in certain Astragalus spp. (Leguminosae). Nitrite (NO2-) metabolism was also studied in vitro because rapid NO2- reduction is required for the overall detoxification of NPOH. Intra-rumi...
