Isolation from estuarine sediments of a Desulfovibrio strain which can grow on lactate coupled to the reductive dehalogenation of 2,4,6-tribromophenol

Article Abstract:

The Desulfovibrio strain TBP-1 has been isolated from the marine sediments of the Arthur Kill in the New York/New Jersey harbor. TBP-1 is a gram-negative, motile, vibrio-shaped, obligate anaerobe which thrives on lactate, pyruvate, hydrogen and fumarate in the presence of sulfate as an electron acceptor. It can reduce dehalogenating 2,4,6-tribromophenol to phenol. TBP-1 can accumulate acetate when grown on lactate and sulfate but will not grow in the absence of NaCl.

Influence of alternative electron acceptors on the anaerobic biodegradability of chlorinated phenols and benzoic acids

Article Abstract:

The combination of chloroaromatic compound's anaerobic degradation and denitrification was studied. Freshwater and estuarine-derived sediments were used as the inocula in the anaerobic biodegradation of chlorinated aromatic compounds, with nitrate, sulfate and carbonate as electron acceptors. The presence of competent microbial populations was found to be more related to biodegradability compared to molecular structure.

(super 13)C-carrier DNA shortens the incubation time needed to detect benzoate-utilizing denitrifying bacteria by stable-isotope probing

Article Abstract:

Genetic signatures from denitrifying bacteria capable of benzoate utilization in coastal sediments were discerned using DNA-stable isotope probing (SIP) and (super 13)C-carrier DNA for the physical separation of (super 13)C-DNA. Results suggest that temporal analysis using SIP can be used to illustrate the initial biodegrader in a bacterial population and to document the cross-feeding microbial community.
