A novel EDTA-degrading Pseudomonas sp

A bacterial strain LPM-410 capable of utilizing ethylenediaminetetraacetate (EDTA) as the sole source of energy, carbon, and nitrogen was isolated from sewage sludge and identified as a Pseudomonas sp. on the basis of its phenotypic characteristics. Suspensions of exponential-phase cells degraded ED...

Description
Summary:A bacterial strain LPM-410 capable of utilizing ethylenediaminetetraacetate (EDTA) as the sole source of energy, carbon, and nitrogen was isolated from sewage sludge and identified as a Pseudomonas sp. on the basis of its phenotypic characteristics. Suspensions of exponential-phase cells degraded EDTA, Mg-, Ca-, Ba-, and Mn-EDTA at constant specific rates ranging from 0.363 to 0.525 mmol EDTA/(g cells h). The more stable chelate, Zn-EDTA, was degraded at a lower rate (0.195 ± 0.030 mmol EDTA/(g cells h)), and here was no degradation of Co-, Cu-, Pb-, and Fe(III)-EDTA.[PUBLICATION ABSTRACT]
