Mycelia from Festuca sinensis in Solid Culture>, Formula: C6H10O8, the main research area is Epichloe Festuca sinensis sodium selenite metabolite mycelia solid culture; Culture time; Epichloë sp. from Festuca sinensis; Metabolite analysis; Selenium.
Selenium (Se) is an essential micronutrient with many beneficial effects for humans and other living organisms. Numerous microorganisms in culture systems enrich and convert inorganic selenium to organic selenium. In this study, Epichloe sp. from Festuca sinensis was exposed to increasing Na2SeO3 concentrations (0, 0.1, 0.2, 0.3, and 0.4 mmol/L) in Petri dishes with potato dextrose agar (PDA) for 8 wk. Epichloe sp. mycelia were immediately collected after mycelial diameters were measured at 4, 5, 6, 7, and 8 wk of cultivation, resp. Gas chromatog.-mass spectrometer (GC-MS) anal. was performed on different groups of Epichloe sp. mycelia. Different changes were observed as Epichloe sp. was exposed to different selenite conditions and cultivation time. The colony diameter of Epichloe sp. decreased in response to increased selenite concentrations, whereas the inhibitory effects diminished over time. Seventy-two of the 203 identified metabolites did not differ significantly across selenite treatments within the same time point, while 82 compounds did not differ significantly between multiple time points of the same Se concentration However, the relative levels of 122 metabolites increased the most under selenite conditions. Specifically, between the 4th and 8th weeks, there were increases in 2-keto-isovaleric acid, uridine, and maltose in selenite treatments compared to controls. Selenium increased glutathione levels and exhibited antioxidant properties in weeks 4, 5, and 7. Addnl., we observed that different doses of selenite could promote the production of carbohydrates such as isomaltose, cellobiose, and sucrose; fatty acids such as palmitoleic acid, palmitic acid, and stearic acid; and amino acids such as lysine and tyrosine in Epichloe sp. mycelia. Therefore, Epichloe sp. exposed to selenite stress may benefit from increased levels of some metabolite compounds
