WebIn S. thermophilus and Lb. bulgaricus, lactose is not phosphorylated before it is transported into the cell. In the cell, it is hydrolyzed by β-galactosidase (or lactase) to glucose and galactose. The glucose moiety is converted to glucose-6-phosphate and fermented via the glycolytic pathway. WebIPTG can be transported into cells by galactoside permease and can bind to the lac repressor protein. However, unlike lactose, IPTG is not broken down by β -galactosidase. …
