The biochemistry aspect · Bacteria can grow in a E coli membrane minimum medium(N c H Converted into lts) ose in glycolytic Different carbon sources B-Galactosidase require a unique set of CH, OH Glucose Metabolized metabolizing enzymes a glycolytic two enzymes are required Permease proteins (transpart lactose from for lactose metabolism medium into E coli) lactose Allolactose B-galactosidase induces lactose permease synthesis in E coli in · Galactose epimerase poH B-Galactosidase lactose growth mediumThe biochemistry aspect • Bacteria can grow in a minimum medium (N. C. salts) • Different carbon sources require a unique set of metabolizing enzymes • two enzymes are required for lactose metabolism: -galactosidase lactose permease • Galactose epimerase
