Abstract
Sporomusa termitida reduced caffeate (1mM) in anaerobic, two-liq. phase, reaction systems contg. either tetradecane or 1-butyl-3-methylimidazolium hexafluorophosphate {[bmim][PF6]}(20 vol./vol.). The initial rate and final product yield were 20 and 7% lower, resp., in [bmim][PF6]. Since caffeate partitioned only into the aq. phase, the lower rate cannot be attributed to mass transfer barriers. Therefore, [bmim][PF6] inhibited the biocatalyst, perhaps unsurprisingly since it is very polar and hydrolyzes to produce HF. [on SciFinder (R)]
