不同培养基对内生真菌Fusarium sp.分泌equisetin的影响OA

To investigate the effect of different culture media on the secretion ability of equisetin by the endophytic fungus Fusarium sp.,this study employed HPLC to analyze the ability of the strain to produce equisetin in seven liquid media(PDB,wheat bran,FM4,Peter,YPG,MEB,PYJ)and eight solid media(rice,glutinous rice,brown rice,millet,corn,black rice,mung bean,black bean).The results showed that the strain secreted very low levels of equisetin under liquid culture conditions,with only trace amounts detected in a few media.In contrast,under solid culture conditions,equisetin was successfully produced in six of the eight substrates,except for mung bean and black bean.Among these,rice medium yielded the highest production,reaching 7.73 mg·g-1.In conclusion,solid-state fermentation is significantly superior to liquid fermentation,and rice is a suitable and efficient substrate for equisetin production by this strain.
