一株芽孢杆菌及其在棒曲霉防治中的应用
摘要：
本发明公开了一株芽孢杆菌及其在棒曲霉防治中的应用。该菌株是芽孢杆菌(Bacillus sp.)NA2008-JK1 CGMCC No.2914。该菌株经过发酵后产生对棒曲霉具有拮抗作用的代谢产物。平板菌落的抑菌活性试验结果表明，芽孢杆菌(Bacillus sp.)NA2008-JK1 CGMCC No.2914能明显抑制棒曲霉菌的生长，棒曲霉菌落的平均直径为13.4mm，且棒曲霉随时间的推移不再生长；而对照菌株则不能抑制棒曲霉菌的生长，棒曲霉越过对照菌株继续生长，3天后棒曲霉菌落的平均直径为32.3mm。抑菌圈实验结果表明，芽孢杆菌(Bacillus sp.)NA2008-JK1 CGMCC No.2914发酵滤液在PDA平板上可对棒曲霉产生明显的抑菌圈，抑菌圈的平均直径为15.6mm。
摘要（英）：

The invention discloses a strain of bacillus and application thereof in aspergillus clavatus control. The strain is bacillus sp. NA2008-JK1 CGMCC No. 2914. After fermentation, the strain generates metabolic products which have an antagonistic effect on aspergillus clavatus. The results of a test on the antibacterial activity of the plate bacterial colony show that the bacillus sp. NA2008-JK1 CGMCC No. 2914 can obviously restrain the growth of the aspergillus clavatus, the average diameter of the aspergillus clavatus bacterial colony is 13.4 mm, and the aspergillus clavatus does not grow with the change of time; and a comparison strain can not restrain the growth of the aspergillus clavatus, the aspergillus clavatus exceeds the comparison strain to grow continuously, and the average diameter of the aspergillus clavatus bacterial colony is 32.3 mm after 3 days. The results of the bacteriostatic circle experiment show that the bacillus sp. NA2008-JK1 CGMCC No. 2914 fermented filtrate cangenerate obvious bacteriostatic circles to the aspergillus clavatus on a PDA plate, and the average diameter of the bacteriostatic circles is 15.6mm.
