Root-knot disease caused by Meloidogyne incognita is major soil pathogen and cause severe economic damages to vegetable crops. In this study, we selected rhizobacteria for biocontrol of the root-knot nematode, M. incognita, and identified; performed bioassay of the bacterial extracts in cucumber seedlings. The crude extracts of strains CT16 and JC05 out of 180 strains inhibited egg hatching and increased juvenile mortality in vitro assay; based on 16S rRNA sequences analysis, the two strains were identified as Bacillus sp. CT16, and Neobacillus sp. JC05. After extracting the bacterial supernatants by using various organic solvents, n-butanol and n-hexane extracts of strain CT16 and n-butanol extract of strain JC05 showed inhibitory activity of egg hatching depending on concentrations. Subsequently, n-butanol extracts of two strains significantly suppressed formation of egg masses in cucumber seedling. Therefore, these results indicated that strains CT16 and JC05 could be used as potential biocontrol agents against M. incognita.

“…Lysobacter capsici YS1215 was previously isolated in Korea. It produced the chitinolytic and gelatinolytic enzymes, and showed antifungal and nematicidal activities (Lee et al, 2013a;Lee et al, 2013b;Lee et al, 2014). Hence, the objective of this study is to investigate the best optimal medium composition for the shelf life of the biofertilizer (L. capsici YS1215) using media supplemented with crab shell and gelatin powder, or with commercial TSB media.…”

Biofertilizers are increasingly available in the market as one of the alternatives to chemical fertilizers. The supply of a high number of viable microorganisms is important for farmers. Lysobacter capsici YS1215 producing chitinases and gelatinases, isolated from soil in Korea, was evaluated for the establishment of an optimal medium condition of its shelf life under an in vitro condition. In this study, the population density of a biofertilizer (L. capsici YS1215) in media containing crab shell and gelatin powder (M1, M2, M3 and M4) was observed to be higher than that of populations grown in TSB (Tryptic soy broth) media (M5, M6 and M7) during experimental period. In addition, the population density at 11 months was over 10 6 CFU mL -1 in M1, M3 and M4, but under 10 6 CFU mL -1 in M2, M5, M6 and M7. The best optimal medium for the shelf life was M1 (2.6 × 10 6 CFU mL) containing both chitinous and gelatinous materials at 11 months. Therefore, this study provided results of the appropriate medium composition for the enhancement of the shelf life of L. capsici YS1215.Key words: Shelf life, Biofertilizer, Crab shell powder, GelatinThe log10 (CFU mL
