  A novel isolate capable of producing opulent yields of kojic acid with surface fermentation was screened from ten different isolated soil fungi. The organism was confirmed as Aspergillus flavus FJ537130 strain using 18SrRNA based molecular analysis and it was identified as a negative producer of aflatoxin. Though twelve different carbon sources were used, significant yields of kojic acid crystals was noticed with Sago starch. The optimized conditions established were substrate concentration 1000 ml (100 g of starch powder in 1000 ml of H2O), pH 6.0, Time 28 d, Temperature 28°C, Peptone concentration 4 g/l, KH2PO4 concentration 1 g/l, MgSO4 concentration 0.5 g/l and the yield achieved was 28.5 g/l. The resulted fermentation broth was subjected to solvent extraction followed by gel filtration for the separation of kojic acid and crystallization. The structural characterizat.. View More»
