- This study investigated the decomposing activities on gelatin and egg sac of root-knot nematode
(Meloidogyne incognita). Ten Bacillus isolates (KRB-1~10) isolated from the soils of Mt. Naejang. Among
them, KRB-5, 9, and 10 showed decomposing activities, and identified as Bacillus subtilis KRB-5, Bacillus
amyloliquefaciens KRB-9, and KRB-10 by 16S rRNA sequence analysis, respectively. Under pot experiments
using pepper, 100-fold diluted culture broth of three isolates reduced the number of egg sac on roots collected
60 days and 90 days and increased the growth of aerial part compared with the group only treated with
Meloidogyne incognita. Especially, the group treated B. subtilis KRB-5 was superior in the growth of pepper.
These results suggest that the B. subtilis KRB-5 can be used to control the root-knot nematode on pepper.
