Photobiodegradation of pyridine by Rhodopseudomonas palustris JA1.

A purple non-sulfur bacterium isolated from dairy effluent was identified as Rps. palustris JA1. This organism was able to grow on pyridine as sole source of carbon in a light dependent anaerobic process with a doubling time of 30 h. Intermediates of pyridine photobiodegradation were identified as glycine and malonate, produced in stoichiometric molar ratios with simultaneous utilization, yielding biomass.
