Abstract

La bêta-galactosidase est obtenue par culture d'un micro-organisme appartenant au groupe taxonomique représenté par la culture-type NRLL B-11, 229. L'enzyme isolé des cellules microbiennes résiste à la chaleur et à l'inhibition par le lactose et ses produits d'hydrolyse, de sorte qu'il peut être utilisé avantageusement pour convertir du petit-lait par exemple en un sirop contenant du glucose et du galactose.Beta-galactosidase is obtained by culture of a microorganism belonging to the taxonomic group represented by the standard culture NRLL B-11, 229. The enzyme isolated from microbial cells resists heat and inhibition by lactose and its hydrolysis products, so that it can be advantageously used to convert whey for example into a syrup containing glucose and galactose.
