STUDY OF ALPHA-AMYLASE OBTAINED BY SOLID STATE FERMENTATION OF CASSAVA RESIDUE IN AQUEOUS TWO-PHASE SYSTEMS
Listed in DataCite
Description
Abstract
The α-amylase enzyme was produced by solid state fermentation (SSF) and its partition behavior in Aqueous Two-Phase Systems (ATPS) was determined using systems consisting of polyethylene glycol (PEG) and potassium phosphate buffer. To determine the best conditions for α-amylase production, a central composite design was constructed for two independent variables: fermentation time and moisture content, and for the partition study, a face-centered central composite design (CCF) with four independent variables: PEG molecular weight, pH, temperature and partition time.

It was indicated that the best enzyme production conditions were a fermentation time of 35.0 hours and 45.7% moisture content. From the results obtained, it was found that increasing the polymer molecular weight promotes a reduction of the enzyme concentration in the upper phase, increasing its concentration in the lower phase. It was also observed that the partition coefficients increased with increasing pH values and a reduction in temperature.
