桉树木屑与枯草芽孢杆菌结合对猪肚菇生长影响

Effect of Eucalyptus Sawdust Fermented by Bacillus subtilis on the Growth of Clitocybe maxima

[目的]探讨发酵培养料对菌丝生长与生物转化率的影响。[方法]采用枯草芽孢杆菌对桉树木屑进行发酵处理,研究发酵处理后的桉树木屑对猪肚菇生长影响。[结果]桉树木屑发酵时枯草杆菌的接种浓度以7~9 g/kg较为适宜;发酵时间以10~12 d为宜;发酵过程中,桉树堆料中添加60~90 g/kg的牛粪有助于产量进一步提高,生物学转化率可达66%~69%,明显高于对照及其他处理。[结论]采用经枯草芽孢杆菌发酵处理后的桉树木屑栽培猪肚菇对其菌丝生长与生物转化率均有一定的促进作用。

[Objective]To investigate the effect of fermentation medium on mycelial growth and bioconversion rate.[Method]Eucalyptus sawdust was fermented by Bacillus subtilis to study the effect of Eucalyptus sawdust on the growth of Clitocybe maxima.[Result]It is be beneficial for Mycelial growth,when eucalyptus sawdust was fermented with the inoculation concentration of Bacillus subtilis in 7~9 g/kg,and the fermentation time was 10~12 d.During the fermentation process,adding 60~90 g/kg cow dung to Eucalyptus compost could further improve the yield,and the biological conversion rate could reach 66%~69%,which was significantly higher than the control and other treatments.[Conclusion]Eucalyptus sawdust fermented by Bacillus subtilis could promote the mycelial growth and bioconversion rate of Clitocybe maxima.
