Comprehensive analysis of metabolites in the mycelium of Cordyceps fumosorosea cultured on Periplaneta americana
Annals of Microbiology(2024)
摘要
Background Cordyceps fumosorosea is one of the common species within the Cordyceps genus, which are cultured on Periplaneta americana . This study aimed to determine the composition of bioactive compounds, including β-glucans, polysaccharides, cordycepic acid, flavonoids, ergosterol, and nitrogenous compounds (specifically nucleosides: adenosine, guanosine, adenine, and hypoxanthine), present in the mixture and mycelium at various time incubation. Methods Different bioactive compounds, including β-1,3-glucan, polysaccharides, cordycepic acid, flavonoids, ergosterol, and nitrogenous compounds (specifically nucleosides: adenosine, guanosine, adenine, and hypoxanthine) are detected from C. fumosorosea which cultured on P. americana by UV and HPLC. Results Mycelia of C. fumosorosea were cultivated in P. americana (medium). The highest total β-1,3-glucan content was observed in the mixture ( C. fumosorosea + P. americana ) after 25 days (69.21 ± 0.07 mg/g) and in the mycelium after 25 days (56.32 ± 0.39 mg/g) using different solvents. The highest β-1,3-glucan content was attained at specific time incubation in other solvents. The content of cordycepic acid peaked at 52.28 ± 0.11 mg/g in the mixture after 25 days and at 46.96 ± 0.13 mg/g in the mycelium after 25 days. The polysaccharide content reached its highest level in the mixture after 20 days (16.68 ± 0.38 mg/g) and in the mycelium after 20 days (14.85 ± 0.10 mg/g). The peak flavonoid content was observed in the mixture after 25 days (4.65 ± 0.24 mg/g) and in the mycelium after 25 days (4.04 ± 0.07 mg/g). Nucleosides, including adenine, adenosine, hypoxanthine, and guanosine, exhibited their highest levels after 25 days in the mixture and mycelium. Ergosterol content peaks at 25 days (2.25 ± 0.04 mg/g). Conclusion Cordyceps fumosorosea mixture and time incubation of 20 and 25 days are optimal for detecting a diverse array of bioactive compounds, including β-1,3-glucan, polysaccharides, cordycepic acid, flavonoids, ergosterol, and nucleosides.
