Taurine reduction in anaerobic respiration of Bilophila wadsworthia RZATAU

Article Abstract:

The taurine reducing organism, Bilophila wadsworthia RZATAU strain, converted taurine to ammonia, acetate and sulfide in the presence of an external electron source. The dissimilatory process was dependent on the presence of an external source of electrons that facilitates the utilization of sulfonate by Bilophila wadsworthia RZATAU. Furthermore, the disappearance of taurine from the cell extracts was dependent on the presence of pyruvate which facilitated taurine reduction via anaerobic respiration.

Anaerobic taurine oxidation: a novel reaction by a nitrate-reducing Alcaligenes sp

Article Abstract:

Enrichment cultures utilizing taurine and isethionate were isolated to understand the dissimilatory metabolism of taurine under anoxic conditions. It was found that the NKNTAU strain can use taurine as a source of electrons and carbon under anoxic, nitrate-respiring conditions. Examination of NKNTAU revealed that it utilized only one taurine which was identified as a novel Alcaligenes sp., a facultative anaerobic bacterium.

Anaerobic desulfonation of 4-tolylsulfonate and 2-(4-sulfophenyl) butyrate by a Clostridium sp

Article Abstract:

Experiments are performed to study the feasibility of using arylsulfonate as the sole added source of sulfur in promoting the growth of Clostridium P. strain EV4. Results indicate that the use of arylsulfonate allows anaerobic desulfonation and a growth yield of about three kilograms of protein per mol of sulfur. It also reduces the level of sulfur contamination in the basal medium by 80%.
