Aerobic Growth of Rhodococcus aetherivorans BCP1 Using Selected Naphthenic Acids as the Sole Carbon and Energy Sources

Rhodococcus aetherivorans BCP1 as cell factory for the production of intracellular tellurium nanorods under aerobic conditions

BACKGROUND Tellurite (TeO32-) is recognized as a toxic oxyanion to living organisms. However, mainly anaerobic or facultative-anaerobic microorganisms are able to tolerate and convert TeO32- into the less toxic and available form of elemental Tellurium (Te0), producing Te-deposits or Te-nanostructures. The use of TeO32--reducing bacteria can lead to the decontamination of polluted environments ...

Aerobic growth on nitroglycerin as the sole carbon, nitrogen, and energy source by a mixed bacterial culture.

Nitroglycerin (glycerol trinitrate [GTN]), an explosive and vasodilatory compound, was metabolized by mixed microbial cultures from aeration tank sludge previously exposed to GTN. Aerobic enrichment cultures removed GTN rapidly in the absence of a supplemental carbon source. Complete denitration of GTN, provided as the sole C and N source, was observed in aerobic batch cultures and proceeded st...

Mechanisms for Aerobic Degradation of Commercial Naphthenic Acids

Fatty acids as energy sources.

The notion that fatty acids (FA) can act as a significant source of energy for higher animals has been so much a part of our understanding of metabolism that just to express it seems platitudinous. We can however sharpen the notion a little by suggesting that this is the major function of FA. While protein and carbohydrates can and do act as energy sources they have other quantitatively importa...

Amino acids as energy sources

To discuss amino acids as energy sources seems at first sight a rather bizarre notion. It is not that there are any particular difficulties in accepting the concept, but rather that it seems a somewhat extravagant or whimsical idea, rather like a discussion of caviar as a pig food. Nevertheless, the topic does merit discussion. For some animals protein regularly predominates in the diet. In adu...
