Salinity decreases nitrite reductase gene diversity in denitrifying bacteria of wastewater treatment systems
Article Abstract:
An investigation conducted on the diversity of nirK and nirS in denitrifying bacteria indicate that salinity decreased the diversity in a nitrate-containing saline wastewater treatment system. The conclusion reveal that the predominant nirS clone is related to nirS derived from marine bacteria, and the predominant nirK clone is related to nirK of the genus alcaligenes.

Nitrogen control of atrazine utilization in Pseudomonas sp. strain ADP
Article Abstract:
A simple atrazine degradation assay in resting cell suspensions to characterize nitrogen control of the atrazine catabolic pathway in Pseudomonas sp. strain ADP is used. Results clearly show that certain nitrogen sources have an inhibitory effect on the catabolic pathway that is not prevented by the simultaneous presence of atrazine in the medium.

Enhanced mineralization of [U-(super 14)C]2,4-dichlorophenoxyacetic acid in soil from the rhizosphere of Trifolium pratense
Article Abstract:
The causes for the rhizosphere-enhanced biodegradation due to selective enrichment of degraders through growth on compounds produced by rhizodeposition were explored. The results demonstrated that enhanced mineralization in Trifolium pratense rhizosphere soil is not due to enrichment of 2,4-D-degrading microorganisms in rhizodeposits.
