CONSTRUCTION OF A NUTRIENT MEDIUM FOR SUSTAINABLE BIOSYNTHESIS OF CYCLODEXTRIN GLYCOSYLTRANSFERASE FROM <i> PAENIBACILLUS EHIMENSIS</i> IB-739
In order to achieve sustainable biosynthesis and get an increase in the activity of сyclodextrin glycosyltransferase (CGTase) from bacteria Paenibacillus ehimensis IB-739 we have performed a search for suitable nutrient medium components. It has been found that the presence of calcium ions in the growth medium at a concentration of 1¸2 g/l inhibits extracellular polysaccharides during cultivation and stabilizes the activity at a higher level.
