Light as an important environmental factor can affect growth,life cycles,morphological characters and secondary metabolism of fungi.Light is a necessary environmental factor for the stroma formation and development of Cordyceps militaris.Effects of blue light on the growth of fruit body,anti-oxidative enzyme activities and bioactive compounds in two different strains,strain 85 and strain 138,of C.militaris were studied.It was indicated that blue light could not increase the superoxide dismutase (SOD) activities but could increase the content of carotenoids significantly of C.militaris.There were no significant differences in the yield of fruit bodies,catalase (CAT) activity and the content of adenosine and mannitol under blue and natural illuminations.The influences of blue light on the peroxidase (POD) activities,polysaccharide content and cordycepin content were different in the two strains.
