%X Benzophenone and bisphenol A are environmental pollutions, which have been listed among ¡°chemicals suspected of having endocrine disrupting effects¡± by the World Wildlife Fund, the National Institute of Environmental Health Sciences in the USA and the Japanese Environment Agency. The cultured cells of Nicotiana tabacum glycosylated benzophenone to three glycosides, 4-O-¦Â-D-glucopyranosylbenzophenone (9%), diphenylmethyl ¦Â-D-glucopyranoside (14%), and diphenylmethyl 6-O-(¦Â-D-glucopyranosyl)-¦Â-D-glucopyranoside (12%) after 48 h incubation. On the other hand, incubation of benzophenone with immobilized cells of N. tabacum in sodium alginate gel gave products in higher yields, i.e. the yields of 4-O-¦Â-D-glucopyranosylbenzophenone, diphenylmethyl ¦Â-D-glucopyranoside, and diphenylmethyl 6-O-(¦Â-D-glucopyranosyl)-¦Â-D-glucopyranoside were 15, 27, and 22%, respectively. Bisphenol A was converted into three glycosides, 2,2-bis(4-¦Â-D-glucopyranosyloxyphenyl)propane (16%), 2-(4-¦Â-D-glucopyranosyloxy-3-hydroxyphenyl)-2-(4-¦Â-D-gluco- pyranosyloxyphenyl) propane (8%), and 2-(3-¦Â-D-glucopyranosyloxy-4-hydroxyphenyl)-2-(4-¦Â-D-glucopyranosyloxyphe nyl)propane (5%). Also the use of immobilized N. tabacum cells improved the yield of products; the glycosylation of bisphenol A with immobilized N. tabacum gave 2,2-bis(4-¦Â-D-glucopyranosyloxyphenyl)propane (24%), 2-(4-¦Â-D-gluco- pyranosyloxy-3-hydroxyphenyl)-2-(4-¦Â-D-glucopyranosyloxyphenyl) propane (15%), and 2-(3-¦Â-D-glucopyranosyloxy- 4-hydroxyphenyl)-2-(4-¦Â-D-glucopyranosyloxyphenyl)propane (11%).
