| 摘 要： | 从我国不同地区采集土样,共分离到300余株芽胞杆菌,通过平板对峙生长法从中筛选到4株对香蕉枯萎病原菌有明显拮抗作用的菌株.经16S rRNA序列分析,将这4株生防芽胞杆菌鉴定为多粘类芽胞杆菌.4株菌的生物学特性基本一致,其主要脂肪酸类型为15:0 ANTEISO,分析发现生防菌对病原菌的抑菌作用与生防菌的脂肪酸类型具有... |

| Abstract: | More than three hundred Bacillus spp.were isolated from the soil samples in China,and there were four strains that had effective in suppression Fusarium oxyspomm f sp.cubense on PDA agar plates.These four strains were identified as Paenibacillus polymyxa based on 16S rRNA sequence.There were similar biological characterics,and main fatty acid type was 15∶0 ANTEISO among those strains.There are correlation between the inhibitory effect and some fatty acid based on DPS soft analysis.The characterization,such as different account,temperature,pH and UV time,were studied,and the effect of 4 Paenibacillus polymyxa against Fusarium oxyspomm f sp.cubense were also studied in this study.The results showed that the effect of four Bacillus species were decreased by concentration,and sensitive to temperature.And four strains had strong inhibitory effect at pH9,and not sensitive to UV.The results showed that that strain FJAT-4539 was the strongest strain to inhibit banana wilt disease among the four Bacillus spp. |
