Abstract

|
|
Effects of vitamins, metabolic intermediates and several inorganic mineral salts on the biomass and lipid accumulation of Mucor plumbeus were investigated after 15 days of incubation at 37¡É under static culture condition. The optimum concentrations of various vitamins were 1 ¥ã/§¤ for biotin, and 0.01 g/§¤ for nicotinic acid, pyridoxine, thiamine and riboflavin. Among them pyridoxine was the most stimulatory. The maximum felt weight and lipid content per 50§¢ medium were 2.82¡¾.014 g and 62.8%. Triglyceride content of neutral lipid produced under this condition was 64.9%. The major fatty acids were oleic acid (50.0%), linoleic (23.8%) and palmitic acid (13.9%). Malonic acid was considered not to be desirable even though it stimulated the biomass and lipid accumulation because triglyceride content was lowered considerably comparing with control. MgSO©þ¡¤7H©üO was the most stimulatory among the various magnesium salts and its optimum concentration was 5 g/§¤. Mucor plumbeus did not require NaH©üPO©þ for the stimulation of felt and lipid production. However, the addition of MnCl©ü at the concentration of 2 g/§¤ was stimulatory to show 2.76¡¾0.28g of felt/50 §¢ and 56.4% lipid content, and 73.9% triglyceride in the neutral lipid.
