Abstract
Present study concerns with the nutritional and physiological roles of monascorubrin against Monascus anka, a new strain to produce a natural pigment.
When 0.02g of monascorubrin was added to the medium containing 3ml of 99.5% ethanol, 0.01 mol of monobasic ammonium phosphate, 0.1g of monobasic potassium phosphate, 0.05g of magnesium sulfate in 100ml water, the growth and pigment production were considerably improved. Cultivation was carried out on a rotary shaker (150rpm) for 15 days at 30°C.
The results indicated that monascorubrin was not only an excreted material of Monascus anka but might had a activity for the fungus the improvement of utilization of ethanol as a carbon source.
