title: Isolation and characterization of dibenzofuran-degrading Serratia marcescens from alkalophilic bacterial consortium of the chemostat.
abstract: Alkalophilic bacterial consortium developed by continuous enrichment in the chemostat in presence of 4-chlorosalicylic acid as sole source of carbon and energy contained six bacterial strains, Micrococcus luteus (csa101), Deinococcus radiothilus (csa102), csa103 (Burkholderia gladioli), Alloiococcus otilis (csa104), Micrococcus diversus (csa105), Micrococcus luteus (csa106), identified by the Biolog test method. The strains were tested for utilization of organic compounds in which one of the strains (csa101) had higher potency to utilize dibenzofuran (DF) as sole carbon and energy source identified as Serratia marcescens on the basis of 16S rDNA. The degradation of DF by bacterial strain proceeded through an oxidative route as indicated by 2,2'3-trihydroxybiphenyl, 2-hydroxy-6-(2-hydroxyphenyl)-6-oxo-2,4-hexadienoic acid, salicylic acid, and catechol, which was identified by gas chromatography-mass spectrometry.
