Abstract

Ethanol production by Zymomonas mobilis NRRL-806 was assessed using different enzymatic hydrolysates from pretreated Eucalyptus globulus saw dust pulp. Results showed that when enzymatic hydrolysate containing 79.5 g L-1 of glucose and 8.81 g L-1 of acetic acid, a maximum ethanol yield 92% and a productivity of 1.16 g L-1 h-1 were obtained, with a total of 37 g L-1 of ethanol after 27 h. Acetic acid concentration present in enzymatic hydrolysates was the main factor that contributed to decrease ethanol yield and productivity, in the case of hydrolysate E, where acetic acid concentration was higher (12.8 g L-1), ethanol yield and productivity were 80% and 0.99 g L-1 h-1 respectively.
