Three bacterial strains were isolated, which used the synthetic chelating agent iminodisuccinate (IDS) as sole carbon source for growth in mineral salts media (MSM). Taxonomic analysis and 16S rDNA sequence analysis identified one of these isolates (B3), which was isolated from sewage sludge, as a strain of Achromobacter xylosoxidans subsp. xylosoxidans. It exhibited a doubling time of approximately 3 h in liquid MSM supplemented with IDS and grew even in the presence of 1.0% (w/v) IDS. Since photometric and high performance liquid chromatography analysis showed that IDS, which came onto the market only recently as an alternative for ethylenediaminetetraacetate, was completely degraded by axenic cultures of bacteria; it will probably be readily degraded in the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
