摘要:4-vinylphenol,which is widely used in the synthesis of
condiments,polymers and resins,has been paid many attentions due to its
hepatotoxic and pneumotoxic effects to organisms as the metabolite of
styrene in rats and human. Using biotransformation technology to
decrease 4-vinylphenol toxicity will be of practical significance.
Current studies investigated the biotransformation conditions of
4-vinylphenol by strain PH_(_IND),and the optimal conditions were as
OD_(600) of PH_(_IND) 2.5, 4 -vinylphenol concentration 1 mmol/L,pH 8
and glucose concentration 20 mmol/L. Under the optimal conditions,the
biotransformation obeyed the first -order kinetics, and transformation
rate reached approximately 31% after 180 min. Molecular docking
indicated that 4-vinylphenol could interact with the active site of
alpha-subunit of the phenol hydroxylase and LC-MS analysis demonstrated
that 4-vinylphenol could be transformed to 4-vinylcatechol by strain
PH_(_IND).
