Characteristics of anaerobic oxalate-degrading enrichment cultures from the rumen

Enrichment, isolation and characterization of anaerobic oxalate-degrading bacteria from the rumen

Improving the Nutritional Value of Ziziphus Spina-Christi using Degrading Bacteria Isolated from the Rumen

Extended Abstract Introduction and Objective: Tannins have many limiting effects on consumption, nutrient digestion, growth and performance, palatability. There are many plants and by-products that are limited in animal feed due to the high content of anti-nutritional compounds such as tannins. The use of methods that can reduce the amount of these compounds will allow their use in animal feed...

Generation of a proton motive force by the anaerobic oxalate-degrading bacterium Oxalobacter formigenes.

The generation of transmembrane ion gradients by Oxalobacter formigenes cells metabolizing oxalate was studied. The magnitudes of both the transmembrane electrical potential (delta psi) and the pH gradient (internal alkaline) decreased with increasing external pH; quantitatively, the delta psi was the most important component of the proton motive force. As the extracellular pH of metabolizing c...

Tetrachloromethane-Degrading Bacterial Enrichment Cultures and Isolates from a Contaminated Aquifer

The prokaryotic community of a groundwater aquifer exposed to high concentrations of tetrachloromethane (CCl₄) for more than three decades was followed by terminal restriction fragment length polymorphism (T-RFLP) during pump-and-treat remediation at the contamination source. Bacterial enrichments and isolates were obtained under selective anoxic conditions, and degraded 10 mg·L(-1) CCl₄, with ...

Phylogenetic analysis of anaerobic psychrophilic enrichment cultures obtained from a greenland glacier ice core.

The examination of microorganisms in glacial ice cores allows the phylogenetic relationships of organisms frozen for thousands of years to be compared with those of current isolates. We developed a method for aseptically sampling a sediment-containing portion of a Greenland ice core that had remained at -9 degrees C for over 100,000 years. Epifluorescence microscopy and flow cytometry results s...
