OPTIMIZATION OF PIGMENT AND BIOMASS PRODUCTION FROM FUSARIUM MONILIFORMEUNDER SUBMERGED FERMENTATION CONDITIONS

摘要

Objective: This study aimed at improving the medium composition for efficient and economical production of pigment and mycelial biomass from the native isolates of Fusarium moniliforme by submerged culture. Methods: The effect of cultural conditions like different production medium, temperatures, pH, incubatio n period, carbon sources, nitrogen sources, amino acids and metal salts on pigment and biomass production were studied. Results: The optimum productivity of the pigment and biomass was achieved with optimized process parameters containing potato dextrose broth (PDB 2% w/v), temperature (28oC), pH (5.5), incubation period (8 days), carbon source (glucose 2% w/v), nitrogen source (peptone 1% w/v), amino acid (methionine 0.5%) and metal salts (KH2PO4 0.5%). Conclusion: We hope that the intensive study on the pigment constituents from Fusarium moniliforme will lead to the discovery of a novel pharmaceutical and insecticidal property
