Pomegranate seeds were found to be the best substrate
and with 0.1% w/v Potassium dihydrogen phosphate
(KH2PO4), 5% w/v glucose, 60% w/w moisture, pH 5
with 15 days fermentation cycle under optimized solid
state fermentation conditions, 4.2 ± 0.03 mg lovasta-
tin/gm dfm was produced. Suitability of substrate was
found to depend on presence of fats in the substrate.
Further increase in productivity was obtained by muta-
tion studies using Ethyl Methyl Suplphonate (EMS) to
give a maximum lovastatin yield of 6.5 ± 0.07 mg/gm
dfm. Thus a SSF process for pomegranate seeds utiliza-
tion was developed with the aim to make pomegranate
processing industry a truly profitable venture.
