溶杆菌属细菌鉴定及生防机制概况
Advance in bacteria identification and biocontrol mechanism of Lysobacter spp.

溶杆菌属的大部分细菌具有重要的生防前景，因而受到了高度关注。为了明确目前溶杆菌属细菌的研究现状，分析了已报道的26种溶杆菌属细菌的分布环境及典型的生化特征，基于16S rDNA序列相似性和脂肪酸组成构建了26种溶杆菌属细菌的系统进化树，并辅以DNA-DNA杂交结果进行佐证，阐述了溶杆菌属细菌对病原菌、线虫病害的生物防治物质及其作用机理，并对其生物安全和应用前景进行了展望。
Widely attention has been paid to Lysobacter species since they can inhibit growth of pathogens.The distribution environment and typical biochemical characteristics of 26 reported Lysobacter species were analyzed and their phylogenetic tree was conducted based on 16S rDNA sequence similarity and fatty acid composition.DNA-DNA hybridization results were used as evidence.Then,the biological control of pathogenic bacteria and nematodes of Lysobacter species were discussed and the biosafety and application for biological control were introduced
