Fig. 1From: Enhanced lignin degradation by Irpex lacteus through expanded sterilization further improved the fermentation quality and microbial community during the silage preservation processDynamics of the pH value (a) and organic acids (b–e) in different treatments. CK, raw buckwheat straw; EX, expanded straw; CIL and EIL represent CK and EX groups treated with I. lacteus for 14 days respectively; CP, CIP, and EIP represent the silage of CK, CIL, EIL group respectively for 3, 7, 14, 28 daysBack to article page
