A new approach to microbial production of gallic acid

In a new approach to microbial gallic acid production by Aspergillus fischeri MTCC 150, 40gL(−1) of tannic acid was added in two installments during the bioconversion phase of the process (25gL(−1) and 15gL(−1) at 32 and 44h respectively). The optimum parameters for the bioconversion phase were foun...

description In a new approach to microbial gallic acid production by Aspergillus fischeri MTCC 150, 40gL(−1) of tannic acid was added in two installments during the bioconversion phase of the process (25gL(−1) and 15gL(−1) at 32 and 44h respectively). The optimum parameters for the bioconversion phase were found to be temperature: 35°C, pH: slightly acidic (3.3–3.5), aeration: nil and agitation: 250 rpm. A maximum of 71.4% conversion was obtained after 71h fermentation with 83.3% product recovery. The yield was 7.35 g of gallic acid per g of biomass accumulated and the fermenter productivity was 0.56 g of gallic acid produced per liter of medium per hour.
