“…The highest nitrogen (12%) and protein (75%) dry matter contents were produced by the Eri silkworm (Samia ricini D.). Consequently, the Eri silkworm could enhance mycelial formation better than the other insect supplementations, at least at 14 d. The findings in the current study were consistent with those of Wongsorn et al (2021), who reported on silkworms that had been used to cultivate Cordyceps and had increased mycelial formation. According to Laursen (2018), the radial mycelial growth and thickness significantly differed depending on the available nitrogen source for three strains of Pleurotus ostreatus.…”

“…and mealworm larvae (Tenebrio molitor L.) were bought from local organic farms in Nakhon Ratchasima, Thailand. The protein content of each edible insect has been reported by Wongsorn et al (2021), with the highest amount in the Eri silkworm (75.0%), followed by house cricket (65.36%), field cricket (55.87%), silkworm (52.44%), giant water bug (49.79%), mealworm (49.06%) and sago palm weevil (24.52%). Furthermore, they reported that sago palm weevil, mealworm, giant water bug, silkworm, field cricket, house cricket and Eri silkworm had average nitrogen contents on a dry matter basis of 3.92%, 7.85%, 7.97%, 8.39%, 8.94%, 10.46%, and 12.01%, respectively.…”

Importance of the work: Isaria tenuipes is an entomopathogenic fungus that has been used as a traditional medicine due to its biochemical and pharmaceutical properties. Preliminary research revealed that medium supplemented with insects promoted mycelial growth and cordycepin production. Objectives: To evaluate the suitability of edible insects as a substrate for I. tenuipes cultivation and to investigate the mycelial growth, formation of fruiting bodies and concentrations of cordycepin and adenosine. Materials & Methods: Seven edible insects were used as nitrogen sources in I. tenuipes cultivation. The mycelial growth on potato dextrose agar with different edible insects was measured on days 7, 14 and 21. Fruiting body formation and bioactive compounds were analyzed 60 d after being cultured on brown rice medium containing each edible insect. Results: Eri silkworm (Samia ricini D.) and silkworm were used to produce the fastest mycelial development on days 7 and 14, with the most extended colonies recorded at 90 mm on day 21; however, this was not significantly different from mealworm, sago palm weevil and the control. The fresh and dry weights of fruiting bodies increased in the brown rice media containing Eri silkworm. The highest cordycepin content (244 mg/100 g) and the highest adenosine content (57.7 mg/100g) were found in the fruiting bodies cultured on brown rice supplemented with Eri silkworm. Main finding: Eri silkworm could be suitable for use as a nitrogen source in I. tenuipes cultivation, resulting in a high amount of bioactive compound content.

“…Cordyceps is traditionally collected in the wild, but it is very rare and difficult to secure. Due to these limitations, studies on Cordyceps production have been performed for a long time using various methods ( Tuli et al, 2013 ; Kontogiannatos et al, 2021 ; Wongsorn et al, 2021 ; Zeng et al, 2021 ). Since Cordyceps can be grown in culture, cultivation is widely used for securing its supply.…”

Cordyceps mushroom with increased cordycepin content by the cultivation on edible insects

et al. 2022

Cordycepin is the major constituent of Cordyceps mushroom (or Cordyceps militaris) with therapeutic potential. Insects are the direct sources of nutrients for Cordyceps in nature. Therefore, optimized condition of Cordyceps cultivation for efficient cordycepin production was explored using six edible insects as substrates. The highest yield of cordycepin was produced by the cultivation on Allomyrina dichotoma and was 34 times that on Bombyx mori pupae. Among insect components, fat content was found to be important for cordycepin production. Especially, a positive correlation was deduced between oleic acid content and cordycepin production. The transcriptional levels of cns1 and cns2, genes involved in cordycepin biosynthesis, were higher in Cordyceps grown on A. dichotoma than on other insects tested. The addition of oleic acid to the substrates increased cordycepin production together with the transcriptional levels of cns1 and cns2. Therefore, Cordyceps with high content of cordycepin can be secured by the cultivation on insects.
