Isolation and identification of novel geosmin-degrading bacteria
Copyright policy )Isolation and identification of novel geosmin-degrading bacteria
Three novel geosmin-degrading bacteria were isolated from the sediments of Lake Kasumigaura, Japan. All strains were identified as Acinetobacter spp. by 16S rRNA gene sequence analysis and can biodegrade geosmin at an initial geosmin concentration of 2 mg/L after 2 days. Furthermore, at an initial geosmin concentration of 40 microg/L, geosmin removal was more than 68per cent by GSM-2 strain, and the degradation mechanism followed a pseudo-first-order mode. A rate constant of 0.026 reveals rapid geosmin degradation. This is the first report on geosmin degradation by by Acinetobacter spp.
