Effects of light and heavy metals on Cordyceps militaris fruit body growth in rice grain-based cultivation

Abstract

The objective of this study was to examine the light and heavy metals on the fruit body growth of Cordyceps militaris in the rice-based cultivation. Since heavy metals are commonly detected in the paddy field, we investigated the effect of lead, cadmium and mercury on the rice grain-based cultivation of C. militaris. Cordycepin and cordycepic acid were determined by HPLC method. The result showed that the best fruit body growth and bioactive complements was obtained in rice I under 12 h light/dark cycle conditions. The effects of heavy metals (Pb, Hg, and Cd) to the fruit body were remarkable-the inhibition carried a dose-dependent behavior.

Effect of nutrition, vitamin, grains, and temperature on the mycelium growth and antioxidant capacity of Cordyceps militaris (strains AG-1 and PSJ-1)

“…In recent years C. militaris is extensively cultivated in liquid as well as solid media and is the most successfully cultivated Cordyceps species (Das, Masuda, Sakurai, & Sakakibara, 2010b;Sung, 1996). Reported that the solid media different supplemented grain types and seeds are used, such as millet, rye, rice, brown rice, bean powder, corn grains, cottonseed hulls, sorghum, corn cobs, wheat, sunflower floral discs (Chen & Wu, 1990;Chen, Liu, & Chang, 2011;Gao & Wang, 2008;Holliday, P, Loomis-Powers, & Patel, 2004;Li, Tong, Bai, & Fan, 2004;Li, 2002;Shrestha, Han, Sung, & Sung, 2012;Wei & Huang, 2009;Wen, Li, Kang, Kang, & Hyde, 2014;Yi. et al, 2014).…”

Effect of strain separated parts, solid-state substrates and light condition on yield and bioactive compounds ofCordyceps militarisfruiting bodies

“…The blue light can obtain better yield and quality of fruiting bodies. The light conditions, including wavelengths, intensity, and light/dark cycle had the greatest impact on the bioactive compound production (Chen et al, 2011;Chiang et al, 2017). Based on these results, during the period of the primodium formation with red light and fruiting bodies growth with white light maybe can improve the yield and quality of fruiting bodies.…”

“…The carbon/nitrogen ratios affected the cordycepin and adenosine content clearly (Lim et al, 2012;Shih, Tsai, & Hsieh, 2006). The cordycepin also affected by the nutrients (Chen, Liu, & Chang, 2011). The quality differences of fruiting bodies harvested from different substrates maybe because the fruiting bodies growth period and nutrients composition of wheat and rice.…”

Review: The endless nutritional and pharmaceutical benefits of the Himalayan gold, Cordyceps; Current knowledge and prospective potentials

“…The development of C. militaris stroma cultivation in-vitro started with using insects to grow stromata by Leatherdale (1970) followed by laboratory trials using various organic substrates by Yue et al (1982). For commercial production of C. militaris stromata, cereals including rice have been widely used (Wen et al 2008;Chen et al 2011). Also, using substrates such as wheat grains, cottonseed coats, corn cobs, corn grain, bean powder, millet, and sorghum have shown promising results (Chen and Wu 1990;Zhang and Liu 1997;Wang 2008, Wei and.…”
