Summary of "Degradation of Phenylurea Herbicides by a Novel Bacterial Consortium Containing Synergistically Catabolic Species and Functionally Complementary Hydrolases."


ABSTRACT:
Phenylurea herbicides (PHs) are frequently detected as major water contaminants in areas where there is extensive use. In this study, Diaphorobacter sp. strain LR2014-1, which initially hydrolyzes linuron to 3,4-dichloroanaline, and Achromobacter sp. strain ANB-1, which further mineralizes the produced aniline derivatives, were isolated from a linuron-mineralizing consortium despite being present at low abundance in the community. The synergistic catabolism of linuron by the consortium containing these two strains resulted in more efficient catabolism of linuron and growth of both strains. Strain LR2014-1 harbors two evolutionary divergent hydrolases from the amidohydrolase superfamily Phh and the amidase superfamily TccA2, which functioned complementarily in the hydrolysis of various types of PHs, including linuron (N-methoxy-N-methyl-substituted), diuron, chlorotoluron and fluomethuron (N,N-dimethyl-substituted) and siduron. These findings show that a bacterial consortium can contain catabolically synergistic species for PH mineralization and one strain could harbor functionally complementary hydrolases for a broadened substrate range.

Medical and Biotech [MESH] Definitions

The passage of viable bacteria from the gastrointestinal tract to extra-intestinal sites, such as the mesenteric lymph node complex, liver, spleen, kidney, and blood. Factors that promote bacterial translocation include overgrowth with gram-negative enteric bacilli, impaired host immune defenses, and injury to the intestinal mucosa resulting in increased intestinal permeability. These mechanisms can act in concert to promote synergistically the systemic spread of indigenous translocating bacteria to cause lethal sepsis.

A class of natural cyclic peptide antibiotics produced by certain subspecies of STREPTOMYCES. They include two structurally unrelated components, STREPTOGRAMIN GROUP A and STREPTOGRAMIN GROUP B, which generally act synergistically to inhibit bacterial growth.
