บทคัดย่อ (EN): Thirty eight mannanase-producing bacteria were isolated from 12 soil samples, which located inside and outside Roi Et Rajabhat University. The mannanase screening was carried out on Luria-Bertani agar containing locust bean gum (LBG) stained with iodine solution. After screening, two isolates that exhibited the highest halo ratio were selected and named KP1 and KP4. Mannanase activity was determined by DNS method using LBG as substrate at 50, 55 and 60 oC. The mannanase activity of KP1 and KP4 at 60oC for 5 mins. was 0.89 and 1.17 U/min, respectively, and at 60oC for 30 mins. was 0.35 and 0.26 U/min, respectively. KP1 and KP4 strains were identified by partial 16S rDNA gene sequence, biochemical test and morphology. The results of bacterial identification revealed that KP1 as Bacillus subtilis and KP4 as Bacillus amyloliquefaciens.
