Sažetak
The simplex method has been used to optimise the inulinase production by Aspergillus niger strain 13/36 with respect to 5 components of the medium. The extracellular enzyme activity was almost 80 U/mL, and over 1.6-fold higher than the results obtained by the classical »one-factor-at-a-time« method. The greatest advantage of the simplex method is that the optimum factor levels were determined in only 12 iterative steps, shortening a typical optimum search process considerably. This is the first use of the simplex method for optimising inulinase production.
