AI Technical Summary

Technical Problem

The lack of a dedicated fermentation medium for *Shortwave Monoclonalella spp.* in current technology results in poor functionality and efficiency in controlling plant root-knot nematodes.

Method used

A fermentation medium containing yeast powder, peptone, nematode lysate, chitin, and yeast extract was designed. By adding chitin and nematode lysate as inducing factors, *Syntrophus spp.* produced anti-nematode components.

Benefits of technology

The fermentation broth has a mortality rate of over 95% against southern root-knot nematodes, rapidly killing the nematodes before the larvae enter the plant, thus providing excellent control.

Abstract

本发明公开了一种华西短波单胞菌发酵培养基及其在防治植物根结线虫中的应用。所述华西短波单胞菌发酵培养基中每升发酵培养基包括质量或体积的组分：酵母粉6‑10g / L，蛋白胨16‑18g / L，线虫裂解液31‑45ml / L，几丁质0.8‑2.5g / L，酵母提取物5.6‑6g / L，pH值6.5‑6.8。所述发酵液培养基的应用是采用其得到的发酵液在防治植物根结线虫中的应用。采用本发明提供的发酵培养基对华西短波单胞菌1.547‑1进行发酵得到的发酵液对植物根结线虫的致死率超过95%，作用时间不超过12小时，能在幼虫进入植株前快速杀死线虫，在防治植物根结线虫上具有良好的应用前景。
