Significance and Impact of the Study: Ionizing radiation is widely applied for food preservation and for correction of the gut microbiome of patients treated with radiation, rescuers, astronauts, etc. Some lactic acid bacteria (LAB) are of great potential in restoring the microbiome of patients, or in food biopreservation. This investigation revealed the radioresistance of Lactobacillus rhamnosus MDC 9661 with only some loss of antibacterial activity, maintaining other activities and the absence of an immunogenic effect. So, it is a potential probiotic organism for the treatment of target people groups. The results showed that co-aggregation is one of the LAB resistance mechanisms which can be used in future to select effective strains.

The purpose of the article is to present the concept of the history of Azerbaijan on the basis of a critical analysis of Azerbaijani school history textbooks. The task was set to identify the main approaches of Azerbaijani authors to the issues of the "historical territory of Azerbaijanis", their origin and formation, as well as claims to the territory of neighboring peoples. The work uses the historical-critical method. As part of the latter, an attempt was made to identify the consistent distortion of information from historical sources in Azerbaijani textbooks, and its motives, while highlighting both the true meaning of the mentioned information and presenting new information demonstrating the falsifications of Azerbaijani authors.
