D. Faure et al., PHENOLIC DERIVATIVES RELATED TO LIGNIN METABOLISM AS SUBSTRATES FOR AZOSPIRILLUM LACCASE ACTIVITY, Phytochemistry, 42(2), 1996, pp. 357-359
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.
