It wasdetected for the ability of a local fungus A.niger, A.alternata, F.oxysporum,
F.solaniandP.devirsum to produce the enzyme lipase in solidmedium including Triputyrin.
The enzymic activity of P.devirsum fungus is distinction from other fungus,
while the
fungus A.alternata failed to produce the lipase. Then they tested quantitatively using a
liquid center to determine the best conditions for best growth to fungus P.devirsum and for
best produce to enzyme lipase. It indicates that corn oil is the best carbonic source for
growth of fungus after 5 days of incubation, as biomass reached(15.99g/L) and effective of
lipase (67.43%).And it found that the concentration of 2% of the corn oil has achieved best
biomass
(17.83g/L) and best production of enzyme lipase effectively(72.78%). Temperature 34 c
achieved the highest biomass (18.94g/L) and best production of enzyme lipase (76.16%),
and pH =7 was the best for the growth of fungus in biomass reached (21.87g/L) and
production of lipase effectively (82.93%). While the nitrogenic source gave peptone
biggest value to biomass (27.08 g/L) and highest production for enzyme (88.12%) in
optimal conditions reached.
