摘要
From the culture medium of Ralstonia (formerly Burkholderia or Pseudomonas) pickettii DSM 6297 grown under iron-limited conditions an iron complexing compound (siderophore) could be isolated. The structure of the isolated polycarboxylate siderophore was determined by spectroscopic methods as S,S-rhizoferrin, the enantiomer of R,R-rhizoferrin produced by fungi (Zygomycetes). Transport experiments with radiolabelled iron using S,S- and R,R-rhizoferrin showd no differences in the bacterial Ralstonia strain, while transport of R,R-rhizoferrin was superior in the producing fungal Rhizopus strain, suggesting stereoselective recognition in the fungus.
