Abstract
The analysis of the literature on the microbiome composition and metabolic properties of kefir available at the RSCI and Web of Science was carried out. Kefir has been used by humans for centuries. It is a useful product of mixed lactic and alcoholic fermentation, produced using evolutionally established associative cultures, collected in an aggregated state termed kefir grains. General characterization of kefir grains from the territorial zones of different continents (Russia, Europe, Asia, and America) is provided. The methods for differentiation and identification of individual species are described, as well as their interactions within the community. The diversity of microbial composition of kefir grains depending on local cultivation conditions and storage processes is shown. The microorganisms present in kefir have a number of properties that determine their metabolism, interaction in the community, beneficial effects on human health and immune system, which is important for the prevention and control of bacterial and viral infections, especially during the COVID-19 pandemic.

Abstract
Lactic acid bacteria (LAB) are the dominant and advantageous microorganisms of raw and fermented camel milk; these bacteria have the potential to develop functional camel-milk-derived products and can be used in dairy technology. This article presents data on the diversity of LAB, isolated from raw and fermented camel milk. In total, from two samples of raw camel milk and one sample of fermented camel milk, seventeen isolates of LAB were isolated. The data of genetic identification of strains, which was performed through analysis of the 16S rRNA gene sequence, is presented. According to this data, the prevailing number of LAB belong to the Lactobacillus genus - 53%. Following species of Lactobacillus bacteria were determined - fermentum, casei, curizae, oryzae, brevis, plantarum, rhamnosus, paracasei. The next prevailing number of lactic acid bacteria belong to the Pediococcus genus - 23%, represented by acidilactici and pentosaceus species. Lactic acid bacteria of Weissella and Enterococcus genera comprised 12% each from total abundance. These results can be used for a further selection of potential starter cultures for functional camel-milk-derived products.

Tracking of Intentionally Inoculated Lactic Acid Bacteria Strains in Yogurt and Probiotic Powder. Microorganisms 2019; 8:microorganisms8010005. [PMID: 31861385 PMCID: PMC7022703 DOI: 10.3390/microorganisms8010005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 12/15/2019] [Accepted: 12/16/2019] [Indexed: 12/20/2022] Open
Abstract
The present work aimed at tracking intentionally inoculated lactic acid bacteria (LAB) strains in yogurt and probiotic powder. Leuconostoc (Leu.) mesenteroides (11251), Lactobacillus (L.) brevis (B151), and Lactobacillus plantarum (LB41K) strains were tracked in yogurt, and L. plantarum (LB41P) was tracked in a commercial probiotic powder. The yogurt was intentionally inoculated with the selected bacterial strains. Two types of yogurt with known and unknown bacterial pools were utilized. The standard 16S rRNA gene sequencing was used to evaluate the initial screening. The molecular typing tools, random amplified polymorphic DNA (RAPD), repetitive element palindromic PCR (rep-PCR), and comparative gene sequence analysis of selected housekeeping loci were used to track the inoculated dubious strains. Out of 30 random selections for each inoculation, the developed method identified seven (11251), nine (B151), and five (LB41K) colonies in the yogurt. The validation was performed by identifying 7 colonies (LB41P) out of 30 in the probiotic powder. The DNA banding profiles and the gene sequence alignments led to the identification of the correct inoculated strains. Overall, the study summarizes the use of molecular tools to identify the deliberately inoculated LAB strains. In conclusion, the proposed polyphasic approach effectively tracked the intentionally inoculated strains: Leu. mesenteroides, L. brevis, and L. plantarum (LB41K) in yogurt and L. plantarum (LB41P) in probiotic powder. The study demonstrates how to track industrially relevant misused LAB strains in marketable food products.

Abstract
Lactic acid bacteria strains are commonly used for animal and human consumption due to their probiotic properties. One of the major genera used is Lactobacillus, a highly diverse genus comprised of several closely related species. The selection of new strains for probiotic use, especially strains of Lactobacillus, is the focus of several research groups. Accurate identification to species level is fundamental for research on new strains, as well as for safety assessment and quality assurance. The 16S-23S internal transcribed spacer (ITS-1) is a deeply homologous region among prokaryotes that is commonly used for identification to the species level because it is able to acquire and accumulate mutations without compromising general bacterial metabolism. In the present study, 16S-23S ITS regions of 45 Lactobacillus species (48 strains) were amplified and subjected to independent enzymatic digestions, using 12 restriction enzymes that recognise six-base sequences. Twenty-nine species showed unique restriction patterns, and could therefore be precisely identified solely by this assay (64%). This approach proved to be reproducible, allowing us to establish simplified restriction patterns for each evaluated species. The restriction patterns of each species were similar among homologous strains, and to a large extent reflected phylogenetic relationships based on 16S rRNA sequences, demonstrating the promising nature of this region for evolutionary studies.
