The influence of cultural conditions, especially glucose concentration and C/N ratio, in a high concentration sugar medium on cell growth and lipid accumulation of Mortierella isabellina IFO 7884 fungus was investigated. M. isabellina was capable of growing in over a 200g/L glucose medium with little effect on cell growth. The high concentration of sugar in the medium accelerated lipid accumulation. The content of lipid cultivated in a high concentration sugar medium exceeded that in a low concentration sugar medium at the same C/N ratio. Maximum dry cell and total lipid weights of 156.4 and 83.1g/L were observed for a 390g/L glucose medium (C/N ratio=20). The highest lipid productivity, however, was found to be 0.69g/Lh for a 270g/L glucose medium (C/N ratio=20).
