Abstract:
Aspergillus oryzae RIB40 possesses the gene of glutaminase (Micrococcus luteus K-3-type glutaminase; AoGls), which has 40% homology with the salt-tolerant glutaminase from M. luteus K-3 (Micrococcus glutaminase). It was found that AoGls is a salt-tolerant enzyme, and its properties are similar to those of Micrococcus glutaminase.

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:29Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically.
