Abstract

Abstract:

Simplicillium lanosoniveum has been reported to have a variety of biological effects， and has been traditionally used as a biological control agent. However， there were few reports on its liquid fermentation. In this study， a hyphomycetous fungus SL001 isolated from Stemonitis splendens was identified as S. lanosoniveum through morphology and phylogenetic analysis. Then， taking mycelial biomass and exopolysaccharides yield as indicators， the composition and proportion of fermentation medium were optimized through single-factor and orthogonal experiments to clarify the nutritional needs of liquid fermentation.The results showed that the highest mycelial biomass and exopolysaccharides yield were harvested under the nutritional conditions of 40 g·L^-1 maltose， 3 g·L^-1 peptone and 1 g·L^-1 KH₂PO₄， and the influence on mycelial biomass of S. lanosoniveum was maltose>peptone>KH₂PO₄. Finally， the culture conditions were further optimized based on nutritional needs. The results showed that the optimum liquid fermentation conditions were 28 ℃， pH 5.5， 150 r·min^-1， 80 mL/250 mL and 6% inoculum size. The mycelial biomass and exopolysaccharides yield were as high as 1.69 g·100 mL^-1 and 3.968 mg·mL^-1 respectively， which were significantly different from the control （P<0.01）. This work provides a theoretical basis for further research on antibacterial agent function and industrial production of S. lanosoniveum.

摘要：

真菌Simplicillium lanosoniveum已被报道具有多种生物学效应，往往被用作生物防治。然而，有关其液体发酵的研究却很少。通过形态学和系统发育分析，鉴定了1株从发网菌属中分离出的丝孢真菌SL001，即S. lanosoniveum。以菌丝生物量和胞外多糖产量为指标，通过单因素和正交实验优化发酵培养基的组成和比例，以阐明液体发酵S. lanosoniveum的最优培养条件。结果表明，在麦芽糖40 g·L^-1、蛋白胨3 g·L^-1和KH₂PO₄ 1 g·L^-1的营养条件下，S. lanosoniveum的菌丝生物量和胞外多糖产量最高，对S. lanosoniveum菌丝生物量的影响程度由大到小依次为麦芽糖>蛋白胨>KH₂PO₄。最后，根据营养需求对培养条件进一步优化。结果显示，最佳培养条件为麦芽糖40 g·L^-1，蛋白胨3 g·L^-1，KH₂PO₄ 1 g·L^-1，培养温度28 ℃，pH 5.5，转速150 r·min^-1，装液量80 mL/250 mL，接种量6%。在最佳培养条件下，菌丝生物量和胞外多糖可达到最大值1.69 g·100 mL^-1和3.968 mg·ml^-1，与对照组相比有显著差异（P<0.01）。通过单因素和正交实验得到真菌S. lanosoniveum的最佳液体发酵条件，为进一步研究S. lanosoniveum的抗菌作用和工业化生产提供了理论依据。
