The viability and symbiotic properties of active strain Bradyrhizobium japonicum 46 after its long-term storage using different methods were studied. It was established that strain storing in evaporative freezing conditions as well at periodic passages the strain preserves its ability to form active symbiosis with soybean plants. Long-term storage under the layer of mineral oil had negatively influenced on the symbiotic properties of B. japonicum 46 strain resulted in only partial restoration of strains virulence, nitrogen fixing activity and competitiveness.

Preservation of strains of bradyrhizobia is an important aspect of legume research and development. Storage of strains of bradyrhizobia in sterile water is an inexpensive and simple method of preservation. This study was conducted to determine if bradyrhizobia strains remained viable after being stored in water for 66 months. Twenty-three bradyrhizobia strains were viable and pure after 66 months of storage in water. Nine Bradyrhizobium japonicum strains that were resistant to antibiotics remained viable and pure after 60 months of storage in water. However, three of the nine antibiotic-resistant strains lost antibiotic resistance after storage as assessed by failure to grow on yeast extract mannitol agar plates containing antibiotics. Maintenance in water should be limited to 48 months, at which time bradyrhizobia strains can be revived in media containing appropriate antibiotics and resuspended in water. These results demonstrated that bradyrhizobia strains can remain viable for at least 66 months of storage in water, but these bacteria may lose traits such as antibiotic resistance if stored too long in sterile water.Key words: bradyrhizobia, storage, water.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.

The introduction and active use of information transmission and storage systems in the Ministry of Defense (MoD) of Ukraine form the need to develop ways of guaranteed removal of data from media after their use or long-term storage. Such a task is an essential component of the functioning of any information security system. The article analyzes the problems of guaranteed destruction of information on magnetic media. An overview of approaches to the guaranteed destruction of information on magnetic media of different types is presented, and partial estimates of the effectiveness of their application are given by some generally accepted indicators of performance evaluation. The article also describes the classification of methods of destruction of information depending on the influence on its medium. The results of the analysis revealed the main problems of application of software methods and methods of demagnetization of the information carrier. The issue of guaranteed destruction of information from modern SSD devices, which are actively used in the formation of new systems of information accumulation and processing, became particularly relevant in the article. In today's conditions of development of the Armed Forces of Ukraine, methods of mechanical and thermal destruction are more commonly used today. In the medium term, the vector of the use of information elimination methods will change towards the methods of physical impact by the pulsed magnetic field and the software methods that allow to store the information storage device, but this today requires specialists to develop new ways of protecting information in order to avoid its leakage.
