Application

Application Comment Organism
synthesis the CGTase-glyoxyl derivative allow the production of cyclodextrin at 85°C, giving twice the production rate compared to the free enzyme, 17.5% higher mass selectivity for beta-cyclodextrin and may help avoid microbial contamination. These characteristics are important considerations for the development of an industrial CD production continuous process Thermoanaerobacter sp.
