Abstract: Two strains named Tni-9 and Se-9 were isolated from Trichoplusia ni midgut by CV026 report system. The 16S rDNA sequences of the isolates were studied, blast analysis and the phylogenetic tree showed their 16S rDNA were highly homologous to that of Enterococcus mundtii ATCC 43186. By the physiological and biochemical characteristics, the strain Se-9 was further confirmed belong to Enterococcus mundtii .TLC analysis present that Se-9 could produce C6-HSL and 3OC6-HSL quorum sensing signals respecctively.
