| Abstract: | A new mutant of Monascus mold capable of producing yellow pigment was studied in this paper.The biological characteristics and key parameters of the pigment in the submerged culture were examined,including inoculum size,pH,carbon resources and nitrogen resources.The results showed that a hish concentration of yellow pigment with single absorpfion peak at 370hm could be produced by this strain under the conditions of the optimal inoeulum size of 10%(v/v),pH 4.6～5.7,com as carbon resource and NH4NO3 as nitrogen resource.The color value of the yellow pigment produced by Monascus waft 200u/ml and it could be obtained from a flask under these conditions.The content of citrinin in the product detected by us was less than 0.1mg/1. |
