Strains for Protecting Cucumber Plants from Root-Knot Nematode in a Greenhouse.

Kofoid et White is one of the most dangerous root-knot nematodes in greenhouses. In this study, we evaluated two strains ( BZR 86 and BZR 277) as promising microbiological agents for protecting cucumber plants from the root-knot nematode Kof. The morphological and cultural characteristics and enzymatic activity of the strains have been studied and the optimal conditions for its cultivation have been developed.

Biological control of important fungal diseases of potato and raspberry by two strains.

Stem canker and black scurf caused by are the important diseases in potato, while spur blight caused by is a major disease in red raspberry. In Western Siberia, both crops are grown predominantly in small-scale farming that requires maximal usage of biological products for plant protection instead of chemicals. We evaluated two promising strains BZR 336 g and BZR 517 isolated in the south of Russia (45°1'N, 38°59'E) for their biological control potentials against the potato and red raspberry diseases under the more severe weather conditions of Western Siberia (55°1'N, 82°55' E).

Optimization of laboratory cultivation conditions for the synthesis of antifungal metabolites by bacillus subtilis strains.

In order to achieve the optimal number of colony forming units and a high level of antifungal metabolites synthesis, we carried out the periodic cultivation of the BZR 336 g and BZR 517 strains at various pH and temperature levels. In the experiment for determining the optimal temperature, the maximum titer of BZR 336 g bacterium (1.6-1.
