Abstract
Activity of bacterial Azospirillum lipoferum laccase on phenolic deriv atives was studied by spectrophotometry, HPLC and GC/MS. Phenolic comp ounds of the syringic type (aldehyde, acid or acetophenone) were trans formed into 2,6-dimethoxy-1,4-benzoquinone (2,6-DMBQ). Comparison has been made with the fungal Pyricularia oryzae laccase. Transformation o f other phenolic acid derivatives, related to lignin metabolism, have been studied with both bacterial and fungal enzymes, using spectrophot ometric analysis.
