This study showed that the addition of certain compounds separately such
as KH2PO4 , K2SO4 , corn steep liquor or yeast extract had affected gibberellic
acid production from wild strain of Fusarium moniliforme. Corn steep liquor at the
concentration 0.25 gm/L gave 92.31 mg/L of gibberellic acid, while potassium
sulphate at the concentration 0.20 gm/L gave 91.95 mg/L of gibberellic acid,
potassium dihydrogen phosphate gave the highest production where reached 93.48
mg/L especially at the concentration 0.5 gm/L, at the concentration 1.5 gm/L yeast
extract gave 93.15 mg/L of gibberellic acid. The initial pH for highest production
of gibberellic acid was 5.5 . The optimal incubation temperature to produce
highest yield of acid was 30° C.
