Effect of adsorbants on in vitro biohydrogenation of 22:6n-3 by mixed cultures of rumen microorganisms.
Studies on microbial biohydrogenation of fatty acids in the rumen are of importance as this process lowers the availability of nutritionally beneficial unsaturated fatty acids for incorporation into meat and milk but also might result in the accumulation of biologically active intermediates. The impact was studied of adsorption of 22:6n-3 (DHA) to particulate material on its disappearance durin...
متن کاملEnrichment of Denitrifying Methane-Oxidizing Microorganisms Using Up-Flow Continuous Reactors and Batch Cultures
Denitrifying anaerobic methane oxidizing (DAMO) microorganisms were enriched from paddy field soils using continuous-flow and batch cultures fed with nitrate or nitrite as a sole electron acceptor. After several months of cultivation, the continuous-flow cultures using nitrite showed remarkable simultaneous methane oxidation and nitrite reduction and DAMO bacteria belonging to phylum NC10 were ...
متن کاملAssimilation of Inorganic Cobalt into Rumen Microorganisms
Assimilation of ionic cobalt by axenic cultures of four species of anaerobic rumen bacteria was measured using 6oCo as cobalt (II) chloride. Uptake could be measured in all four species but may not represent active accumulation in the case of Lactobacillus casei and Propionibacterium acnes. Significant uptake (89.5% of 6oCo present) was demonstrated by Selenomonas ruminantium from media contain...
متن کاملEffect of Different Ratios of Concentrate and Roughage on Lipid Synthesis by Rumen Microorganisms In Vitro
The effect of different feeding ratios of concentrate to roughage on ruminal lipid synthesis in vitro was examined. Three sheep fitted with a rumen fistula were fed three different ratios (8:2, 4:6 and 0:10) of concentrate and roughage, and their rumen liquor were used for incubation. C-labeled glucose or sodium acetate as substrate was added to cultures of rumen liquor, and they were incubated...
متن کاملMetabolism of glycine by rumen microorganisms.
Rumen microorganisms rapidly metabolized glycine at rates varying from 0.014 to 0.241 mumole of glycine per ml per min. The main metabolic products were carbon dioxide, acetic acid, and ammonia; little glycine was incorporated into bacterial protein. Use of carboxyl or methylene-labeled glycine showed that the carbon dioxide came mainly from the carboxyl of glycine, whereas both carbons of acet...
