Abstract
Cowpea Rhizobium RA-1 produced a catechol-like siderophore. Secondary hydroxamic acids were not detected. Bioassay of the siderophore exhibited a distinct zone of growth of cowpea rhizobia. One litre of culture filtrate gave 6.2 mg of catechol-like siderophore. Glycine and threonine were detected in the siderophore. Maximum production of siderophore was found at 36 h of growth of cowpea Rhizobium RA-1.
