Abstract
Pseudomonas aeruginosa MTB-1 does not degrade gamma-hexachlorocyclohexane (γ-HCH), but this bacterium persistently coexists with a γ-HCH-degrading strain, Sphingomonas sp. MM-1, in a microbial community enriched by the technical formulation of HCH. Here we report the complete MTB-1 genome sequence, with a 6.6-Mb circular chromosome.
Highlights
Pseudomonas aeruginosa MTB-1 does not degrade gamma-hexachlorocyclohexane (␥-HCH), but this bacterium persistently coexists with a ␥-HCH-degrading strain, Sphingomonas sp
Our previous use of a microbial community enriched by technical formulation of HCH (t-HCH) from t-HCH-contaminated soil in India [5] led to the successful isolation of a ␥-HCH-degrading bacterium, Sphingomonas sp. strain MM-1 [3, 4], and a non-␥-HCH-degrading bacterium, Pseudomonas aeruginosa MTB-1 [3]
The strains MM-1 and MTB-1 have been deposited in the Japan Collection of Microorganisms (JCM) under the accession numbers JCM 19685 and JCM 19686, respectively
Summary
Pseudomonas aeruginosa MTB-1 does not degrade gamma-hexachlorocyclohexane (␥-HCH), but this bacterium persistently coexists with a ␥-HCH-degrading strain, Sphingomonas sp. The technical formulation of HCH (t-HCH) mainly consists of an insecticidal ␥-isomer and noninsecticidal ␣-, -, and ␦-isomers. Our previous use of a microbial community enriched by t-HCH from t-HCH-contaminated soil in India [5] led to the successful isolation of a ␥-HCH-degrading bacterium, Sphingomonas sp. Strain MM-1 [3, 4], and a non-␥-HCH-degrading bacterium, Pseudomonas aeruginosa MTB-1 [3].
