Laccases and other phenoloxidases are mainly distributed in various plants and higher fungi. In the present study, a riverine bacterial isolate identified as Bacillus sphaericus was found to exhibit a laccase-like activity. This was proved by specific substrate reactions, sensitivity to specific inhibitors and also by catalytic reactions all of which delivered results closely resembling those obtained for fungal laccases used as references. The laccase-like activity of a B. sphaericus strain ...Laccases and other phenoloxidases are mainly distributed in various plants and higher fungi. In the present study, a riverine bacterial isolate identified as Bacillus sphaericus was found to exhibit a laccase-like activity. This was proved by specific substrate reactions, sensitivity to specific inhibitors and also by catalytic reactions all of which delivered results closely resembling those obtained for fungal laccases used as references. The laccase-like activity of a B. sphaericus strain showed a distinct correlation with the formation of spores. No laccase-like activity was observed extracellulary or in cell-free extracts. » weiterlesen» einklappen
