We compared antibacterial activity of various extracts of two licorice subspecies against Staphylococcus aureus, Escherichia coli, and Bacillus subtilis. Diethyl carbonate extracts of Glycyrrhiza glabra root from Astrakhan region (Russia) exhibited maximum activity against the test microbial strains; activity of Astrakhan licorice was superior among 50% ethanol extracts from Astrakhan (Russia) and Calabria (Italy). Antibacterial activity is directly proportional to the content of glycyrrhizin and 18β-glycyrrhetinic acid in the extracts. According to preliminary data, the content of these chemical components in Glycyrrhiza glabra root from Astrakhan region is higher than in licorice growing in Italy, which is presumably related to climate and geographic characteristics of Astrakhan region.

Subject. Practiced involuntarily to counteract the spread of the coronavirus in educational institutions, online learning turned to be the only effective solution ensuring the sustainable and uninterrupted educational process in the highly uncertain circumstances the world faced. The managerial decision on online learning induces many implications for everyone involved into the educational process and the educational system. Thus, it can be undertaken again in similar situations in the future. So, we need to have the profound understanding of the mechanism.
Objectives. We study what students think about their educational process when they have to learn remotely. Therefore, we identify strengths and weaknesses of online learning.
Methods. The methodological framework relies upon proceedings on remote learning and the impact of the digitalization on the educational process. The study involves methods of generalization, comparative analysis, sociological survey.
Results. As the sociological survey reveals, students tend to new formats of learning during the pandemic. This is due to a lack of personal communication with teachers and their classmates.
Conclusions and Relevance. Referring to most of the respondents, we conclude that the new form of learning proved to be rather effective in the current situation when people have to work and learn remotely during the coronavirus pandemic.
