Production of α-amylase and saccharomyces cerevisiae biomass by using by-products from food industry

Anotace: In this research the production of α-amylase enzyme using Bacillus spp. bacteria, and biomass production of Saccharomyces cerevisiae yeast using three types of media were assayed. The production of α-amylase enzyme is realized through two types of fermentations, liquid fermentation where bacterial culture Bacillus spp. is cultivated in LB medium, and solid-state fermentation where industrial wastes such as potato and banana peels are used as substrate. Cultivation of Saccharomyces cerevisiae yeast is done using three different media: Yeast-Peptone-Dextrose, Yeast-Peptone-Sucrose and molasses. Based on the obtained results, it is concluded that the process of enzyme production using industrial waste, as well as yeast biomass production has a potential, which should be further researched.
