“…They are known as chemoorganoheterotrophs using a variety of sugars, but they are incapable of utilizing alcohols, amino acids and organic acids. Verrumicrobia are extremely widespread in soils, rhizosphere, freshwater or marine reservoirs and in human digestive tract [ 58 , 59 , 60 , 61 ]. They are one of the most dominant in the composition of prokaryotic communities of soils and are mostly uncultivated.…”

Bacterial communities associated with medicinal plants are an essential part of ecosystems. The rhizosphere effect is rather important in the cultivation process. The purpose of the study was to analyze the rhizosphere effect of oregano (Origanum vulgare L.), peppermint (Mentha piperita L.), thyme (Thymus vulgaris L.), creeping thyme (Thymus serpillum L.) and sage (Salvia officinalis L.). To estimate the quantity of 16S bacteria ribosomal genes, qPCR assays were used. To compare bacterial communities’ structure of medicinal plants rhizosphere with bulk soil high-throughput sequencing of the 16S rRNA targeting variable regions V3–V4 of bacteria was carried out. The highest bacterial abundance was associated with T. vulgaris L., M. piperita L. and S. officinalis L., and the lowest was associated with the O. vulgare L. rhizosphere. Phylum Actinobacteriota was predominant in all rhizosphere samples. The maximum bacterial α-diversity was found in S. officinalis L. rhizosphere. According to bacterial β-diversity calculated by the Bray–Curtis metric, T. vulgaris L. root zone significantly differed from bulk soil. The rhizosphere effect was positive to the Myxococcota, Bacteroidota, Verrucomicrobiota, Proteobacteria and Gemmatimonadota.

“…For example, the first metagenome of the bog microbial community was published relatively recently, in 2014 [11]. Much attention is paid to the study of the taxonomic composition of the microbiota of marsh ecosystems, the participation of microbial communities in the transformation of carbon compounds in marsh soils, and the distribution of microbial biomass and its function in various types of peatlands [12][13][14][15]. When microorganisms were identified directly in samples taken from the bog by DNA extraction and analysis, it was found that most of the nucleotide sequences identified in bog peat belong to bacteria of completely unknown groups or groups about which very little is known [16].…”

Composition and Concentration of the Biogenic Components of the Aerosols Collected over Vasyugan Marshes and Karakan Pine Forest at Altitudes from 500 to 7000 m

The purpose of this study was to compare the concentration of total protein, as well as the composition and abundance of culturable microorganisms in atmospheric aerosols collected over the Vasyugan marshes and the Karakan pine forest during a flight in September 2018 at altitudes from 500 to 7000 m. The determined concentrations of total protein in Karakan samples were on average much less than those for the same area in September of other years. The concentration and composition of microorganisms in aerosol samples were determined by cultural methods and isolate genotyping. Altitude dependences of concentrations of total protein and culturable microorganisms were revealed. A rather stable altitude profile of culturable microorganism concentration was found over the Vasyugan marshes. No microorganisms were found at altitudes 4000 and 5500 m over the Karakan pine forest. Non-spore-bearing and spore-forming bacteria, as well as molds and yeast-like fungi, were isolated from aerosol samples. A high concentration of cosmopolitan psychrotolerant yeast Aureobasidium, capable of causing severe mycoses, and opportunistic bacteria Acinetobacter were found. A great similarity of composition and an atypically high abundance of non-spore-bearing bacteria and psychrotolerant yeast-like fungi were revealed in samples taken at altitudes of 1000 and 500 m in both studied regions, which may be a consequence of large-scale horizontal transport of layers of atmospheric air contaminated with microorganisms.
