РІСТ BRADYRHIZOBIUM JAPONICUM ПРИ КУЛЬТИВУВАННІ У ГЕЛЬНОМУ СЕРЕДОВИЩІ
The influence of exopolysaccharideacrylamide (EPAA) in a liquid medium on the growth, retaining of viability and virulence of soybean rhizobia under the periodic cultivation conditions was investigated. It was observed that maximum titer of B. japonicum M-8 (B-7198) and B. japonicum 36 (B-1798) at t...

Agriciltural microbiology| Резюме: | The influence of exopolysaccharideacrylamide (EPAA) in a liquid medium on the growth, retaining of viability and virulence of soybean rhizobia under the periodic cultivation conditions was investigated. It was observed that maximum titer of B. japonicum M-8 (B-7198) and B. japonicum 36 (B-1798) at thickening of medium has increased by 31.4% and 79.4% respectively. In the phase of exponential growth the upward trend in growth activity of rhizobia in the gel medium was observed. It was shown that the B. japonicum 36 is more sensitive than B. japonicum M-8 to the changes in the medium composition and the cultivation conditions. Absolute speed of B. japonicum 36 growth has increased in 5 times while the generation time has decreased in almost 3 times in comparison to the liquid medium. The viability and virulence of both rhizobium strains have remained over five months. It was established that the EPAA is a technological agent for the medium thickening and stabilization of the created on the basis of the soybean nodule bacteria gel preparation. |
