... concentrations were found to decrease with respect to time whilst that of the bioethanol was found to increase with respect to time. The optimum time and temperature for bioethanol production S. cerevisiae ... approximately 48 h to be converted to bioethanol and other products. Therefore, the addition of P. stipitis yeast to S. cerevisiae enhanced the conversion rate of the sugars into bioethanol. ... in production of bioethanol from lignocellulosic biomass. Chem. Eng.
