Tyrosinase is a multifunctional, glycosylated, and copper-containing oxidase, which catalyzes the first two steps in mammalian melanogenesis and is responsible for enzymatic browning reactions in damaged fruits during post-harvest handling and processing. Neither hyperpigmentation in human skin nor enzymatic browning in fruits are desirable. These phenomena have encouraged researchers to seek n...

Kojic acid is a natural organic synthesized during aerobic fermentation of carbohydrates as secondary metabolite by some species Aspergillus and has been used commercially in several industrial applications. The current investigation aims to optimize the culture conditions for kojic production from starch carbon source novel isolate oryzae 1034. Seventy-five isolates representing 11 were isolat...
