The effects of sugars on the glucosylation of exogenous hydroquinone (HQ) was investigated by supplying individual sugars simultaneously with HQ to a suspension culture of Catharanthus roseus cells. The production of arbutin was enhanced as much as 2- to 3-fold by sucrose or glucose at concentrations of up to 6%, with the enhancement being directly dependent on the concentration of the sugar. The exogenously added sugar was not metabolized and remained unchanged. Sorbitol also promoted the production of arbutin in a similar manner. Sucrose improved the viability of cells and, in cultures supplied with sucrose and HQ, the activity of UDP-glucose:hydroquinone glucosyltransferase increased over a much longer period of time than that in control cultures supplemented with HQ only.
