Biotransformation of nitrobenzene by bacteria containing toluene degradative pathways

Biotransformation of phorbol by human intestinal bacteria.

Anaerobic incubation of phorbol (1) from Croton tiglium with human intestinal bacteria afforded five metabolites: isophorbol (2), deoxyphorbol (3), 4beta,9alpha,20-trihydroxy-13,15-seco-1,6,15-tigliatriene-3,13-dione (4), 4beta,9alpha,20-trihydroxy-15,16,17-trinor-1,6-tigliadiene-3,13-dione (5) and 4beta,9a,20-trihydroxy-14(13-->12)-abeo-12alphaH-1,6-tigliadiene-3,13-dione (6). All these metabo...

The Decomposition of Toluene by Soil Bacteria.

The Decomposition of Toluene by Soil Bacteria BY D

SUMMARY Strains of two bacteria, a Pseudomonas and an Achromobacter, which grow with toluene, benzene or certain other related aromatic compounds as sole carbon source were isolated from soil. The use of aromatic compounds by these bacteria was an induced phenomenon. Toluene-grown organisms oxidized without lag toluene, benzene, catechol, &methyl-catechol, benzyl alcohol and, more slowly, o-and...

Anaerobic biotransformation of fluorene and phenanthrene by sulfate-reducing bacteria and identification of biotransformation pathway.

In the present study, anaerobic biotransformation of fluorene and phenanthrene by sulfate-reducing bacteria (SRB) was investigated and biotransformation pathways were proposed. SRB was enriched from anaerobic swine wastewater sludge and its abundance was determined by the fluorescence in situ hybridization (FISH) technique. Batch anaerobic biotransformation studies were conducted with fluorene ...

Biotransformation of phosphogypsum by bacteria isolated from petroleum-refining wastewaters.

The biotransformation of phosphogypsum in cultures of sulfate-reducing bacteria (SRB) isolated from crude petroleum-refining wastewaters or purified using activated sludge method was studied. Selection was with the microcosms method on Postgate and minimal medium with different carbon sources, Emerson medium and petroleum-refining wastewaters. Highest hydrogen sulfide production, in excess of 5...
