The results showed that 13S5 and 13S8 tended to grow faster but sporulate less during subculturing. Sporulation was not significantly different in the first 6 generations, but after subculturing over 6 to 7 generations the sporulation declined significantly, by 81.7% and 69.0% respectively, as compared to that of the first generation.
