Fig. 6From: Production of isoquercitrin from quercetin by biotransformation using Bascillus sp. CSQ10 isolated from Camellia sinensis cultivation soilsDetermination of optimum temperature (A), cell density (B), quercetin feed concentration (C) for quercetin-3-O-(6″-acetyl)-β-d-glucoside production. Biotransformation was performed for 12 h at 30 °C after Bacillus sp. CSQ10 cell densities were adjusted to an OD600 of 0.6. The reaction products were extracted with two volumes of ethyl acetate and analyzed using HPLC. Error bars indicate mean values ± from three independent experimentsBack to article page
