An Arthrobacter sp. exhibiting a clearing activity on humic acid agar plates produced hydroxyl analogous radicals in batch culture. This production was demonstrated by the bleaching of p ‐nitrosodimethylaniline assay and determined by measuring methional‐dependent ethylene generation. This activity relative to no diffusible ·OH radicals, was observed in the slow‐growing, rod‐forming cultures. Inhibition in catalase‐positive cultures suggests a possible role of hydrogen peroxide as a precursor of ·OH, but no direct evidence was found.
