Conjugated linoleic acid accumulation via 10-hydroxy-12-octadecaenoic acid during microaerobic transformation of linoleic acid by Lactobacillus acidophilus

Article Abstract:

Conjugated linoleic acid can be produced by Lactobacillus acidophilus from linoleic acid. Animal studies have shown that conjugated linoleic acid has substantial health benefits, and the cis-9, trans-11-octadecadienoic acid isomer appears to be the most important isomer from a health standpoint.

Engineering cytochrome P450 BM-3 for oxidation of polycyclic aromatic hydrocarbons

Article Abstract:

Researchers have created a bioengineered form of cytochrome P450 BM-3 from Bacillus megaterium that has higher activity against polycyclic aromatic hydrocarbons than the native enzyme. The mutant enzyme could be used to degrade these compounds in polluted soil.

Secretion of flavins by Shewanella species and their role in extracellular electron transfer

Article Abstract:

Flavin mononucleotide (FMN) and riboflavin are identified as the extracellular electron shuttles that are produced by a range of Fe(III)-respiring bacteria such as Shewanella species. The implications of flavin secretion by Shewanella cells living at redox boundaries and their role in extracellular electron transfer are analyzed.
