Sixty-one isolates including molds
yeasts and bacteria from the forest soils collected from Hunan Province
China were tested for their potentiality to accumulate microbial lipid as alternative sources for biodiesel production. The results showed that sixteen mold isolates were potential oleaginous microorganisms
among which
strain SCIM 3.009 was the best lipid producers
which may accumulate up to 50.4% of lipids in dry biomass. Further study showed that the components profile of the lipid from strain SCIM 3.009 had the similar characters to that of vegetable oil
abundant in low degree unsaturated long chain fatty acid (C18:1) and saturated long chain fatty acids (C16:0)
suggesting the lipid is a potential source for biodiesel production. Based on the morphology and a commercial identification system
the strain SCIM 3.009 was found to be Thamnidium ctenidium. To enhance the lipid production by the strain
the fermentation parameters were optimized
the optimium conditions were as follows: glucose as carbon source with initial concentration 60 g/L
NH4NO3 as nitrogen source at 3.0 g/L
culture temperature was 30°C
initial pH = 6.5
culture volume was 50 mL in a 250 mL flask
agitation speed was 220 rpm. Results on verification of the optimium conditions in a 5 L stirred-tank bioreactor reveal that the strain accumulate up to 66.02% of lipids in dry biomass and the lipid yield significantly enhanced from 6.4 ± 0.39 to 13.6 ± 0.37 g/L
while biomass enhanced from 12.7 ± 0.72 to 20.6 ± 0.52 g/L.
