Abstract
New advance in plant–microorganism interactions research revealed the ability of plants to affect the composition of root-associated microbial communities, selecting for the microorganisms required for their growth in different ecosystems under stress conditions. Yeasts can play important roles in promoting plant growth; however, little information is available in this regard. In this study, we evaluated the ability of Rhodotorula mucilaginosa RSRod01 strain isolated from the root nodules of Trifolium sp. collected from a Pb-Zn mine soil to promote plant growth in vitro by producing a siderophore and extracellular enzymes, and exhibiting antifungal activity, as well as its tolerance to heavy metals and salinity. The results showed that the isolate possessed important plant growth-promoting (PGP) traits, including the capacity to grow at 4% salt concentration and resistance to high levels of heavy metals. Resistance to heavy metals decreased in the following row: Pb2+ > Cu2+ > Co2+ > Zn2+ = Ni2+ > Cd2+> Cr6+.

Abstract—
This is the first report on electron microscopic investigation of the effect of bacteriocin on Bacillus anthracis spores. The new bacteriocin, subtilosin P19, isolated from a natural Bacillus subtilis strain, effectively killed dormant B. anthracis spores at concentrations of 0.5‒35 µg/mL after 60-min exposure. Our data, combined with analysis of the known mechanisms of the action of bacteriocins, suggest that the mechanism of spore inactivation was apparently based on multiple disruptions of the integrity of the inner and outer membranes surrounding the cortex of the dormant spore. It is also likely that the molecular configuration of subtilosin P19 allows it to penetrate through the outer integuments and to damage the vital membrane structures of the anthrax spores. Subtilosin P19 can serve as a promising basis for new antimicrobial preparations of natural origin.

Abstract
Starter culture lysis by Lactococcus lactis bacteriophages is one of the leading causes of the fermentation failure in dairy industry. In the present work we performed a PCR grouping of lactophages identified in 73 samples of milk whey obtained from industrial facilities located in Russia. From these samples we isolated 10 novel L. lactis bacteriophages associated with the fermentation failure in different regions of the Russian Federation. The genomes of these bacteriophage isolates are closely related and similar to the known c2-like phages (Ceduovirus genus). However, the allelic variants of the receptor recognition proteins found in these genomes were different.

Abstract
Massive quantitities of waste generated by rising human population and rapid urbanisation are often disposed of into open dumps or landfills. The leachates released from these dumpsites penetrate the soil and can alter the existing biotic communities of the soil. In soil, the microbial communities are the dominant drivers which undergo changes in community structure and diversity in response to the changes in their biotic and abiotic environment. The heterogeneous waste disposed in a dumpsite or a landfill releases leachate containing nutrients along with toxic chemicals and allochthonous microorganisms in the soil. How the microbial community structure and diversity changes in a landfill or a dumpsite soil receiving leachate from it are some important questions from the perspective of microbial ecology. To unravel the community structure of bacteria inthe soil receiving dumpsite leachate and to assess the disturbance diversity relationship in this site, a comparative metagenomic analysis of the soil receiving dumpsite leachate and that of the soil of an adjacent wetland (conserved under Ramsar convention) not receiving dumpsite leachate used as the reference point was done to observe the effect of waste dumping activity on microbial diversity. The microbial diversity of the soil receiving dumpsite leachate and that of the wetland soil were found to differ significantly. Higher microbial diversity was observed in the dumpsite soil, while the wetland soil showed relative dominance of a few microbial taxa.

Abstract—
Microbial communities of the sediments of the Kandalaksha Bay (White Sea) remain insufficiently studied. While the data on the rates of some microbial processes are available, very little is known about microorganisms inhabiting these sediments. In the this study, high-throughput sequencing of variable regions of 16S rRNA genes was used to characterize the microbial communities of 47 Kandalaksha Bay sediment samples collected at 10 cm below the bottom surface. Pseudomonadota and Desulfobacterota were the most abundant phyla, comprising together about a half of all prokaryotes. Determination of the dominant genus-level taxon proved impossible. The most represented chemoorganotrophic microorganisms were uncultured Sandaracinaceae (up to 10.8%) and Woeseia (up to 7.5%). Sulfate-reducing bacteria were important community components in the studied upper sediment layers, with uncultured groups SEEP-SRB1 (up to 7.0%) and Sva0081 (up to 5.9%) being the most abundant. In some samples, the genera Sulfurovum (up to 15.5%) and Thiohalophilus (up to 7.0%) involved in the oxidation of sulfur compounds were found to be important components of the community. Among the archaeal ASVs, the genus Nitrosopumilus oxidizing ammonium to nitrite exhibited the highest relative abundance (up to 6.9% of the total number of prokaryotes). Numerous sequences identified as the 16S rRNA gene fragments of chloroplasts were found in the samples, indicating that the rate of organic matter delivery to the upper sediment layers exceeded the rate of its degradation.

Abstract
The activity of the ethanol extracts of lichens (LE), of the cultures of lichenophilic (endobiotic) fungi (LFE), and of ethanol extracts of these cultures was tested using the following test organisms: Escherichia coli, Salmonella typhimurium, Pseudomonas fluorescens, Staphylococcus aureus, Micrococcus luteus, Enterococcus faecium, Paenibacillus sp., and Candida parapsilosis. Selective activity of LE and LFE against yeasts and gram-positive and gram-negative bacteria was revealed. The extracts from Cladonia rangiferina exhibited no activity against any of the tested cultures. The previously reported locus effect on activity of metabolites of one lichen species was confirmed. Agar block technique was used to detect selective activity of 23 out of 61 analyzed fungal strains against gram-positive and gram-negative bacteria, and of 8 strains, against yeasts. Ethanol extracts of six cultures were shown to suppress the growth of St. aureus, M. luteus, Paenibacillus sp., and E. coli. Strain NM10F28209 from the lichen Stereocaulon paschale, which exhibited inhibitory activity against Ca. parapsilosis was selected for priority development of an antifungal preparation.

Abstract
There are different methods used for the determination of antimicrobial activity of bacteriocins. The most commonly used are the disk-diffusion and dilution methods. The other methods such as point inoculation method, agar overlay assay, cross streak method, radial streak method, agar plug diffusion method, spot-on-lawn assay, Oxford cup method, agar well diffusion assay, and vesicle-based colorimetric assay are also used for the determination of antimicrobial activity of bacteriocins. The inhibitory effect of bacteriocins is dependent on time, concentration and type of bacteriocins. The antimicrobial activity is also dependent on the solid or liquid medium used for the growth of indicator bacteria. A vesicle-based assay which is indicator-independent has also been used for the detection of antimicrobial activity of bacteriocins. In this review, we have discussed the conventional and modern methods which are indicator-dependent and -independent for the detection of bacteriocins and high-throughput screening of bacteriocin-producing strains of lactic acid bacteria.

Abstract
The culture liquid of lactic-acid bacteria (LABs) and bifidobacteria contained secondary metabolites fulfilling signal functions, such as guaiacol and γ-butyrolactone. In addition, 4-hexylresorcinol was detected in the cell extract of Bifidobacterium bifidum 791. No homoserine lactones were produced by the tested microorganisms. The presence of metabolites with signal functions in conjunction with the available data on the synthesis of neuroactive amines, amino acids, and prebiotics by LABs and bifidobacteria indicates that these bacteria can strongly influence the functioning of the whole human symbiotic microbiota as well as the human host’s health state.
