Metabolism of 3-methylindole by a methanogenic consortium

Article Abstract:

Complete mineralization of 3-methylindole (3-MI) was done by a methanogenic 3-MI-degrading consortium derived from wetland soil. However, the consortium was unable to hydroxylate position 3 of oxindole and was unable to mineralize indole. This is evidence that the fermentation of 3-MI did not proceed through the oxindole-isatin pathway. The details of the reaction mechanism are still unknown, and more studies are required.

Prevention of aerobic spoilage of maize silage by a genetically modified killer yeast, Kluyveromyces lactis, defective in the ability to grow on lactic acid

Article Abstract:

Research was conducted to examine the ability of certain yeast strains to prevent spoilage of maize silage fermentation due to aerobic degradation of lactic acid. Results show yeast strain, PCK27, which is unable to grow on lactic acid, improves the aerobic stability of the process.
