| Summary: | —Kojic acid is an organic acid that is widely used as an
ingredient for dermatological products, precursor for flavor enhancer
and also as anti-inflammatory drug. The present study was
undertaken to test the feasibility of pineapple residues as substrate for
kojic acid production by Aspergillus flavus Link 44-1 via solid-state
fermentation. The effect of initial moisture content, pH and
incubation time on kojic acid fermentation was investigated. The best
initial moisture content for kojic acid production from pineapple
residues was observed at 70% (v/w) whereas initial culture pH 2.5
was identified to give high production of kojic acid. The optimal
range of incubation time was identified between 8 and 14 days of
incubation which corresponded to highest range of kojic acid
produced. The results from this study pronounce the promising
usability of pineapple residues as alternative substrate for kojic acid
production by A. flavus Link 44-1. |
