Ing DesignExpert computer software (7.1.four.0) for the ing conditions for IA production (see Table 1), using DesignExpert software program (7.1.four.0) for building of a response surface evaluating the independent variables, and concentration the construction of a response surface evaluating the independent variables, and concenof ammonium sulphate and isoamylisoamyl alcohol. The of nitrogen accessible in whey tration of ammonium sulphate and alcohol. The supply supply of nitrogen obtainable in for K. marxianus is 25 ;is 25 ; due tothe utilization of ammonium sulfate utilised for its whey for K. marxianus because of this, this, the utilization of ammonium sulfate made use of for bioconversion inside the Novo synthesis waswas thought of [14]. its bioconversion inside the Novo synthesis thought of [14]. As a dependent variable for this case, the maximum IA production price was considTable 1.
