    The aim of this study was to isolate microorganisms utilizing crude glycerol as a carbon source efficiently and to evaluate their lipid productivity. Fusarium oxysporum W1 grew well on medium containing 20% crude glycerol as well as 50% pure glycerol. The dry cell weights and total fatty acids of F. oxysporum W1 reached 24.5 g/L and 12.4 g/L. Penicillium sp. N1 and P. citrinum N3 were found to accumulate free fatty acids to as much as 56.2 % and 48.5 % of total fatty acids, respectively, on cultivation in the crude glycerol-containing medium. These strains grew well on medium containing crude glycerol only heat-treated at 80-105°C without autoclave sterilization

    Microbial production of hydroxy fatty acids utilizing crude glycerol

    Strain D2 was isolated from a natural sample as a crude glycerol-assimilating microorganism. The ITS-5.8S rDNA sequence of strain D2 was most similar to that of Fusarium solani deposited in the NCBI database. Strain D2 accumulated 10-hydroxy-cis-12-octadecenoic acid (HYA), 10-hydroxyoctadecanoic acid (HYB), and 10-oxooctadecanoic acid (KetoB) in a medium containing crude glycerol, as a carbon source, and yeast extract, named CG medium. The growth and HYB production of strain D2 depended on the crude glycerol concentration in the medium. Strain D2 produced 2.20 g/L (40% of total fatty acids) of HYB on cultivation in CG medium containing 8% crude glycerol. When strain D2 was cultivated in CG medium containing 6% crude glycerol, the yield of HYB on cultivation under 4 days-shaking and 3 days-static conditions reached 1.19 g/L, which was 2.2 times higher than that under 7 days-shaking conditions and accounted for 53% of total fatty acids. The fungus was found not only to efficiently produce fatty acids utilizing crude glycerol, but also to be the first filamentous fungus to produce hydroxy and oxo fatty acids such as HYB, HYA, and KetoB
