چکیده انگلیسی
On the other hand, various aeration levels (from 0 to 2.5 L/min) were employed. A continuous supply of air was necessary, but no significant improvement in biomass or enzyme production was detected when air flow rates were increased above 1 L/min. Total lipolytic enzyme production reached a maximum of 167 U/L after 3 days, and a relatively high concentration of extra-cellular activity was detected (40% of the total amount). Enzyme yield was around 158 U/g cells. Moreover, it is noteworthy that the lipolytic activity obtained operating at optimal conditions (70 °C and air flow of 1 L/min) was about five-fold higher than that attained in shake flask cultures
