Biotransformation of hydroquinone by hairy roots of Brugmansia candida and effect of sugars and free-radical scavengers.


Hairy roots of Brugmansia candida were used to bioconvert hydroquinone into arbutin. The highest bioconversion, with the lowest damage to the cells, was attained when concentrations of 20-40 mg/L hydroquinone were used. Sugars (sucrose, glucose, mannitol, and sorbitol) at concentrations of 30-120 g/L enhanced bioconversion, and, of these, sucrose was the… (More)
