2.7. Experimental designs and data analysis
2.7.1. Optimization procedure and experimental design
The first optimization step was carried out using ‘one variable
at a time’ experimental approach to identify the significant factors
affecting phytase production by P. purpurogenum GE1.
Production of phytase by P. purpurogenum GE1 was firstly
investigated by using different agro-industrial wastes as a substrate
for solid state fermentation.
