Title: Effect of environmental factors on growth of Nomuraea rileyi MZ060806.
Abstract: The effect of different environmental factors on colony diameter,spore germination rate and yield of Nomuraea rileyi MZ060806 were studied in this paper.The results showed that the effect of temperature on colony diameter,spore germination rate and yield of MZ060806 strain was positive,and the best temperature was 27 ℃,higher or lower temperature inhibited its growth;the lethal temperature was 50 ℃,10 min.The photoperiod of 24 h light could promote sporulation,and 24 h darkness could accelerate its growth of colony.The favorable pH for colony and spore germination was from 6 to 7,and the optimal relative humidity for spore germination was 70 %.Spore germination rate was 92.1 %.Under UV-light(25 W,40 cm) irradiation for 2 min,spore germination rate was 84.4 % after 24 h,and spore germination rate was zero after irradiation for 10 min.
