Abstract:A bacterium strain, designated as H1, was isolated from the inorganic salt medium containing TX-100 as the only carbon source and was capable of degrading high concentrations of TX-100. According to its morphological observation, physiological and biochemical reaction and 16S rDNA (GenBank Accession No.KC505179) sequence analysis, H1strain was identified as Acinetobacter calcoaceticus. The results indicate that the biodegradation process complys with the terminal oxidation model, starting the oxidation of EO end followed the scission of the neighboring ether bond to form the short chains by liberating glyoxylic acid. Plasmid detection and elimination tests show that the gene controlling the degradation of TX-100 is located in plasmid of strain H1.
