Biodegradation of chloromethane by Pseudomonas aeruginosa strain NB1 under nitrate-reducing and aerobic conditions

Article Abstract:

An isolate from the enrichment culture is obtained and its physiology is characterized during anoxic and aerobic growth on chloromethane (CM), including the yield, stoichiometry of nitrate and oxygen consumption, chloride and nitrogen gas release and kinetics. It was seen that the Pseudomonas aeruginosa strain NB1 also grew on methanol, ethanol and acetate under denitrifying and aerobic conditions.

Involvement of coenzyme M during aerobic biodegradation of vinyl chloride and ethene by Pseudomonas putida strain AJ and Ochrobactrum sp. strain TD

Article Abstract:

PCR, hybridization and enzyme assays are used to show the involvement of coenzyme M in aerobic biodegradation of vinyl chloride and ethene in Pseudomonas putida strain AJ and Ochrobactrum sp. strain TD. The results of this analysis have extended the range of eubacteria known to use epoxyalkane:coenzyme M transferase.

Enhanced biotransformation of carbon tetrachloride by Acetobacterium woodii upon addition of hydroxocobalamin and fructose

Article Abstract:

Research was conducted to determine the role of Acetobacterium woodii in the nonenzymatic transformation of carbon tetrachloride (CT). The data show that live cells transform CT to carbon monoxide 30 times faster in presence of hydroxocobalamin and fructose in the culture medium than without.
