用菌丝体生长抑制法检验了 4种拮抗细菌S 1 1、S 1 3、S 1 4和S 1 8的不同细胞组分对水稻纹枯病菌的抑菌作用。初步结果表明 :菌株S 1 8对水稻纹枯病菌起抑制作用的物质主要是脂多糖 (LPS) ;菌株S 1 1对水稻纹枯病菌起抑制作用的物质主要是胞外蛋白。而S 1 3和S 1 4的抑菌成分尚未明了
The mycelial growth inhibition test was conducted to examine the antibacterial activity of four different cell components antagonistic to bacteria such as S 1 1, S 1 3, S 1 4 and S 1 8 against R. solani. The preliminary results showed that LPS was the major inhibitory factor of S 1 8 against R. solani. The major inhibitory factor of S 1 1 to R. solani was extracellular protein. The antibacterial components of S 1 3 and S 1 4 are not yet known
