Abstract:

In the present study, coconut coir was evaluated as an inert support for the production of kojic acid under solid state fermentation using two different production medium as moistening agents for the maximum production of kojic acid. Different parameters such as fermentation time (14 days), Particle size (0.5mm), moisture content (80%), pH (5.0), temperature (30°C) and inoculum size (3 ml/10g carrier) were evaluated as optimized conditions. The combination of rich carbohydrates and rich nitrogen substrates produced higher production (M1, 106 g/kg and M2, 101 g/kg) as compared to un-optimized conditions (80 g/kg and 76 g/kg, respectively). In addition, the yield (M1, 0.106 g/g substrate and M2, 0.101 g/g substrate) and productivity (M1, 0.315 g/kg.h and M2, 0.300 g/kg.h) obtained from the optimization was higher than that obtained from the un-optimized conditions yield (M1, 0.08 g k/g substrate; M2, 0.077 g/kg) and productivity (M1, 0.238 g/kg.h and M2, 0.229 g/kg.h).


Keywords: Screening, Aspergillus oryzae RMS2, kojic acid crystals, coconut coir, carbon and nitrogen sources, solid state fermentation fermentation.
