Isolation and characterization of a fluoranthene-utilizing strain of Pseudomonas paucimobilis.

abstract：:A defined substrate method was developed to simultaneously enumerate total coliforms and Escherichia coli from drinking waters without the need for confirmatory or completed tests. It is a new method based on technology that uses a hydrolyzable substrate as a specific indicator-nutrient for the target microbes. No equ...
