摘要： Strain NF87-2 is an aerobic, non-motile and rod-shaped Gram-negative bacterium. It was isolated from the rhizosphere of green pepper. In the present study, sequence analyses of the 16S rRNA and copA genes revealed that strain NF87-2 belongs to the species Lysobacter capsici. Strain NF87-2 could produce chitinase, cellulase, protease and siderophore. The strain showed a broad spectrum of antifungal activities against phytopathogens, including Alternaria brassicae, Rhizoctonia solani, Sclerotinia sclerotiorum, Botrytis cinerea, Colletotrichum gloeosporioides and Fusarium oxysporum. The secondary metabolites secreted by strain NF87-2 could inhibit the growth of both bacteria and fungi, but the mixture of peptides and proteins extracts from a suspension of strain NF87-2 could only inhibit the mycelia growth of fungi. Our results also have shown that strain NF87-2 could control pepper damping off caused by R. solani effectively in a greenhouse setting. Our findings provide a new source for a biocontrol agent and shed light on the mechanism of the antagonistic activity of L. capsici.
