| Summary: | Kojic acid is a secondary metabolite produced mainly by Aspergillus species. Due to high
demand and wide applications of this product, many research has been done in order to
produce higher yield of this product. In this present work, via submerged fermentation, the
result of screening process showed only one strain out of eight strains being tested produced
kojic acid which is Aspergillus flavus NSH9. Kojic acid production by A. favus NSH9 was
optimized under glucose concentration which is 110 g/L, pH 4 and 107
spore concentration
and the highest kojic acid yield obtained are 15.38 g/L, 30.44 g/L, and 34.06 g/L respectively.
Other than that, the incubation time for the kojic acid production at inoculums size namely
105 and 107 spores/mL were at day 22 and 26 respectively were also determined in this study.
This result indicates the potential of A. flavus NSH9 as one of the producing fungi in this field. |
