| Popis: | Summary In rice paddy soils an active cycling of sulfur compounds takes place. To elucidate the diversity of thiosulfate-oxidizing bacteria these organisms were enriched from bulk soil and rice roots by the most probable number method in liquid medium. From the MPN enrichment cultures 21 bacterial strains were isolated on solid mineral medium, and could be further shown to produce sulfate from thiosulfate. These strains were characterized by 16S rDNA analyses. The isolates were affiliated to seven different phylogenetic groups within the a- and b-subclass of Proteobacteria. Two of these phylotypes were already described as S-oxidizers in this environment (Xanthobacter sp. and Bosea sp. related strains), but five groups represented new S-oxidizers in rice field soil. These isolates were closely related to Mesorhizobium loti, to Hydrogenophaga sp., to Delftia sp., to Pandoraea sp. or showed sequence similarity to a strain of Achromobacter sp. |
