Fusarium nivale (Fr.) Ces., an endophytic fungi from Dendrobium crumenatum Sw. (pigeon orchid) showed an antimicroorganism activity against Absidia corymbifera (Cohn) Sacco& Trotter, causing of human zygomycosis.The aim of this study is to find out the effect of concentration of antimicroorganism agent,fermentation medium, and incubation time to control A. corymbifera by F. nivale; and to make curveof F. nivale growth and curve of its antimicrobial production. Five different concentrations of antimicroorganism agent (0, 75, 150, 225, and 300 f.11),four different fermentation media (Potato Dextrose Yeast, Tauge Extract Broth, Kedelai Extract Broth, and Jagung Extract Broth), and eight differenT incubation times (0, 1, 2, 3, 4, 5, 6, and 7 days) were chosen for this experiment. Parameters of the study were change of filtrate pH, dry weight of mycelial cell of F. nivale, and percentage inhibition of mycelial growth of A. corymbifera. The results indicated that antimicroorganism agent concentration of 150 f.11applied and potato dextrose yeast medium were the most effective to inbibit A. corymbifera. The antimicroorganism agent was produced during growth of the fungi. The production of antimicroorganism agent coinced with the decrease in pH from 6.0 to 4.81; and the increase in pH from 4,81 to 7.24-8.01. A optimum activity of antimicroorganism agent (31,23) during growth of fungi occurred on the 2 day of incubation.
