a method was developed based on the measurement of constitutive beta-glucosidase ( esculinase ) with the repression of this enzyme by bile equivalent ( sodium desoxycholate ) that required only 30 min . p-nitrophenyl-beta-d-glucopyranoside was the esculinase substrate , and sodium desoxycholate was substituted for bile salts .
