Efficient production of sophorose from glucose and its potentially industrial application in cellulase production

Sophorose is the most effective inducer for cellulase production by Trichoderma reesei. Currently, the biosynthesis of sophorose is very inefficient, resulting in that unavailable for cellulase production in industry. In this study, CoGH1A, a multifunctional thermophilic glycoside hydrolase, was employed for sophorose production. Under the optimized conditions, the sophorose yield was 37.86 g/L with a productivity of 9.47 g/L/h which is by far the highest productivity. Meanwhile, the Fe
