Mechanism for Utilization of the -Derived Metabolite Salicin by a - Co-Culture.

GM16 associates with , a model plant in biofuel production. releases abundant phenolic glycosides such as salicin, but GM16 cannot utilize salicin, whereas strains are known to utilize compounds similar to the aglycone moiety of salicin-salicyl alcohol. We propose that the association of to is mediated by another organism (such as OV744) that degrades the glucosyl group of salicin.

Respiratory Vinyl Chloride Reductive Dechlorination to Ethene in TceA-Expressing .

Bioremediation of chlorinated ethenes in anoxic aquifers hinges on organohalide-respiring expressing vinyl chloride (VC) reductive dehalogenase (RDase). The gene encoding the trichloroethene-dechlorinating RDase TceA is frequently detected in contaminated groundwater but not recognized as a biomarker for VC detoxification. We demonstrate that -carrying () strains FL2 and 195 grow with VC as an electron acceptor when sufficient vitamin B (B) is provided.

A carotenoid-deficient mutant of the plant-associated microbe Pantoea sp. YR343 displays an altered membrane proteome.

Membrane organization plays an important role in signaling, transport, and defense. In eukaryotes, the stability, organization, and function of membrane proteins are influenced by certain lipids and sterols, such as cholesterol. Bacteria lack cholesterol, but carotenoids and hopanoids are predicted to play a similar role in modulating membrane properties.

Comparing DNA, RNA and protein levels for measuring microbial dynamics in soil microcosms amended with nitrogen fertilizer.

To what extent multi-omic techniques could reflect in situ microbial process rates remains unclear, especially for highly diverse habitats like soils. Here, we performed microcosm incubations using sandy soil from an agricultural site in Midwest USA. Microcosms amended with isotopically labeled ammonium and urea to simulate a fertilization event showed nitrification (up to 4.
