Cryptococcus humicola JCM 1461 efficiently produced cellobiose lipids (CLs), bolaform biosurfactants. The main product was identified as 16-O-(2″,3″,4″,6′-tetra-O-acetyl-β-cellobiosyl)-2-hydroxyhexadecanoic acid. The production yield of CLs reached 13.1 g/L under the intermittent feeding of glucose. The critical micelle concentrations (CMC) of the main product at pH 4.0 and 7.0 were 3.3×10⁻⁵ M and 4.1×10⁻⁴ M respectively.
