Various carbon sources including monosugars, disaccharides and carboxymethyl-cellulose (CMC) were used for single-cell oil production by the filamentous fungus Mortierella isabellina. In addition, the inhibitory effects of lignocellulose-derived compounds (lignin aldehydes, furan aldehydes and weak acid) were investigated. C6 sugars were preferably used for growth compared to C5 sugars. CMC was not an usable substrate, implying the absence of a cellulase system in this fungus. Lignin derivatives showed the most inhibitory effects, but acetic and formic acids at concentrations of 4g/L improved lipid production, achieving 6.81+/-0.07g/L and 6.66+/-0.33g/L respectively, which was twice as high as that of the control. A 16.8% lipid yield from hydrolysate suggested that this fungus could be useful for microbial lipid production.
