Bioremediation of Bisphenol A and Benzophenone by Glycosylation with Immobilized Marine Microalga Pavlova sp.

Cultured cells of Pavlova sp. glycosylated bisphenol A to its mono-glucoside, 2-(4-beta-D-glucopyranosyloxyphenyl)-2-hydroxyphenylpropane (9%). Use of immobilized Pavlova cells in sodium alginate gel improved yield of the product (17%). On the other hand, Pavlova cell cultures converted benzophenone into diphenylmethanol (49%) and diphenylmethyl beta-D-glucopyranoside (6%). Incubation of benzophenone with immobilized Pavlova cells gave products in higher yields; the yields of diphenylmethanol and diphenylmethyl beta-D-glucopyranoside were 85 and 15%, respectively.
