After 30 d cultivation period, the dried cell weight yield recovered from the medium type II was higher than that recovered from the medium type I (Figure IA and lB). Cultivation time was required for 30 d to obtain the maximal dried cell weight. Similar growth pattern based on dried cell weight was observed (Figure IC and ID). Growth based on the percentage of optical density increment compared to the initial optical density at t = 0 d, was approximately 500 (day 35) and 850 % (day 30) for medium type I and II (Figure IC), respectively, while
