Abstract
OBJECTIVE The need for innovative techniques to preserve microbiota for extended periods, while maintaining the species composition and quantitative balance of the bacterial community, is becoming increasingly important. To address this need, we propose an efficient approach to cryopreserve human gut microbiota using a two-component cryoprotective composition comprising fetal bovine serum (FBS) and 5% dimethyl sulfoxide (DMSO). Fetal serum is a commonly utilized component in the freezing media for eukaryotic cells, however, its effects on prokaryotic cells have not been extensively researched. RESULTS In our study, we demonstrated the high efficiency of using a two-component cryoprotective medium, FBS + 5% DMSO, for cryopreservation of human gut microbiota using three different methods. According to the obtained results, the intact donor microbiota was preserved at a level of 85 ± 4% of the initial composition based on fluorescent analysis using the LIVE/DEAD test. No differences in survival were observed when comparing with pure DMSO and FBS media. The photometric measurement method for growth of aerobic bacteria (A. johnsoni), facultative anaerobes (E. coli, E. faecalis), microaerophilic (L. plantarum), and obligate anaerobic bacterial cultures (E. barkeri, B. breve) also demonstrated high viability rates of 94-98% in the two-component protective medium, reaching intact control levels. However, for anaerobic microflora representatives, serum proved to be a more suitable cryoprotectant. Also, we demonstrated that using cryoprotective media with 50-75% FBS content is enough to preserve a significant level of bacterial cell viability, from an economic standpoint.

Impact of cryoprotective agents on human gut microbes and in vitro stabilized artificial gut microbiota communities. Microb Biotechnol 2024; 17:e14509.

Abstract
The availability of microbial biobanks for the storage of individual gut microbiota members or their derived and artificially assembled consortia has become fundamental for in vitro investigation of the molecular mechanisms behind microbe-microbe and/or microbe-host interactions. However, to preserve bacterial viability, adequate storage and processing technologies are required. In this study, the effects on cell viability of seven different combinations of cryoprotective agents were evaluated by flow cytometry for 53 bacterial species representing key members of the human gut microbiota after one and 3 months of cryopreservation at -80°C. The obtained results highlighted that no universal cryoprotectant was identified capable of guaranteeing effective recovery of intact cells after cryopreservation for all tested bacteria. However, the presence of inulin or skimmed milk provided high levels of viability protection during cryoexposure. These results were further corroborated by cryopreserving 10 artificial gut microbiota produced through in vitro continuous fermentation system technology. Indeed, in this case, the inclusion of inulin or skimmed milk resulted in a high recovery of viable cells, while also allowing consistent and reliable preservation of the artificial gut microbiota biodiversity. Overall, these results suggest that, although the efficacy of various cryoprotective agents is species-specific, some cryoprotectants based on glycerol and the addition of inulin or skimmed milk are preferable to retain viability and biodiversity for both single bacterial species and artificial gut microbiota.

Abstract
BACKGROUND Defining the ability of prebiotic dietary carbohydrates to influence the composition and metabolism of the gut microbiota is central to defining their health impact in diverse individuals. Many clinical trials are using indirect methods. This study aimed to validate collection and fermentation methods enabling their use in the context of clinical studies. METHODS AND RESULTS Parameters tested included stool sample acquisition, storage, and growth conditions. Stool from 3 infants and 3 adults was collected and stored under varying conditions. Samples were cultured anaerobically for two days in the presence of prebiotics, whereupon optical density and pH were measured across time. Whole genome shotgun sequencing and NMR metabolomics were performed. Neither the type of collection vial (standard vial and two different BD anaerobic collection vials) nor cryopreservation (-80 °C or 4 °C) significantly influenced either microbial composition at 16 h of anaerobic culture or the principal components of the metabolome at 8 or 16 h. Metagenomic differences were driven primarily by subject, while metabolomic differences were driven by fermentation sugar (2'-fucosyllactose or dextrose). CONCLUSIONS These data identified a feasible and valid approach for prebiotic fermentation analysis of individual samples in large clinical studies: collection of stool microbiota using standard vials; cryopreservation prior to testing; and collecting fermentation read-out at 8 and 16 hr. Thus, fermentation analysis can be a valid technique for testing the effects of prebiotics on human fecal microbiota.

Abstract
Gut microbiota produce tryptophan metabolites (TMs) important to homeostasis. However, measuring TM levels in stool and determining their microbial sources can be difficult. Here, we measured TMs from the indole pathway in fecal samples from 21 healthy adults with the goal to: 1) determine fecal TM concentrations in healthy individuals; 2) link TM levels to bacterial abundance using 16S and whole genome shotgun (WGS) sequencing data; and 3) predict likely bacterial sources of TM production. Within our samples, we identified 151 genera (16S) and 592 bacterial species (WGS). Eight TMs were found in ≥17 fecal samples, including four in all persons. To our knowledge, we are the first to report fecal levels for indole-3-lactate, indole-3-propionate, and 3-indoleacrylate levels in healthy persons. Overall, indole, indole-3-acetate (IAA), and skatole accounted for 86% of the eight TMs measured. Significant correlations were found between seven TMs and 29 bacterial species. Predicted multiple TM sources support the notion of a complex network of TM production and regulation. Further, the data suggest key roles for Collinsella aerofaciens and IAA, a metabolite reported to maintain intestinal homeostasis through enhanced barrier integrity and anti-inflammatory/antioxidant activities. These findings extend our understanding of TMs and their relationship to the microbial species that act as effectors and/or regulators in the healthy intestine and may lead to novel strategies designed to manipulate tryptophan metabolism to prevent disease and/or restore health to the dysbiotic gut.

Abstract
Animal microbiota is becoming an object of interest as a source of beneficial bacteria for commercial use. Moreover, the escalating problem of bacterial resistance to antibiotics is threatening animals and humans; therefore, in the last decade intensive search for alternative antimicrobials has been observed. In this study, lactic acid bacteria (LAB) were isolated from suckling and weaned pigs feces (376) and characterized to determine their functional properties and usability as pigs additives. Selection of the most promising LAB was made after each stage of research. Isolates were tested for their antimicrobial activity (376) and susceptibility to antibiotics (71). Selected LAB isolates (41) were tested for the production of organic acids, enzymatic activity, cell surface hydrophobicity and survival in gastrointestinal tract. Isolates selected for feed additive (5) were identified by MALDI-TOF mass spectrometry and partial sequence analysis of 16S rRNA gene, represented by Lentilactobacillus, Lacticaseibacillus (both previously classified as Lactobacillus) and Pediococcus genus. Feed additive prototype demonstrated high viability after lyophilization and during storage at 4 °C and − 20 °C for 30 days. Finally, feed additive was tested for survival in simulated alimentary tract of pigs, showing viability at the sufficient level to colonize the host. Studies are focused on obtaining beneficial strains of LAB with probiotic properties for pigs feed additive.

Abstract
Evolving testing methods in food Microbiology have resulted in the need for different types of microbiological reference materials. Based on the research articles available in this area, it is evident that development has been quite substantial in chemical testing compared to Microbiology. The primary reason could be the ease of spiking, and recovery in chemical RM as compared to microbiological RM. A significant challenge faced in recovery and stability during the development of quantitative microbiological RM depends on temperature, type of microbiological media used, method of analysis including reconstitution method, interference due to antimicrobial agents in food matrices, and competitor microorganisms present in higher numbers then the target microorganisms. Most of the research papers published on microbiological reference materials are contributed by developed economies were in the information related to complex food matrices are limited. Further analysis of different International Depository Agencies under the Budapest treaty indicates that there are only three institutes based in Europe providing quantitative or assigned value RM. This, in turn, highlights the scarcity in the availability of quantitative RM in Microbiology. This article provides a global overview of the availability of microbiological RM, microbial preservation techniques, protective agents, and elaboration on developing different formats of microbiological RM used in food testing.

Abstract
A growing body of evidence has demonstrated the importance of the gut microbiome in human health. In general, fecal microbial samples are used to study the mechanisms of relevant diseases. In this context, it is worth mentioning that an optimized cryopreservation method is urgently needed to successfully perform clinical diagnosis, therapy, and scientific investigations of the gut microbiome without affecting its viability and biological activity. In this study, we aimed to test the relative cryopreservation efficiency of different nontoxic natural cryoprotectants using infant fecal and meconium samples. First, we selected two facultative and two obligate anaerobic bacteria as the experimental gut microbial strain to compare these cryoprotectants' toxicity and concentration-dependent bacteria viabilities after cryopreservation, then the viabilities and bacterial diversity of mixed facultative and obligate anaerobic bacteria. Finally, we explored the effects of optimized cryoprotectants for meconium and infant feces after cryopreservation using 16S rRNA sequencing analyses. In addition, to better understand the effectiveness of these cryoprotectants, we used different freeze-thaw conditions mimicking real-life situations in the process of distribution. We found that the better choice for the infant fecal sample's cryopreservation was 100 mg/mL trehalose, whereas 200 mg/mL trehalose/betaine was the optimum choice for meconium cryopreservation. We hope that our results will shed light on the importance of natural cryoprotectants toward the long-term and stable viability of invaluable human gut microbial specimens.

Abstract
Sulfate-reducing bacteria (SRB) are a heterogeneous group of anaerobic microorganisms that play an important role in producing hydrogen sulfide not only in the natural environment, but also in the gastrointestinal tract and oral cavity of animals and humans. The present review was written with the inclusion of 110 references including the time period from 1951 to 2021. The following databases were evaluated: Web of Science, Scopus and Google Scholar. The articles chosen to be included in the review were written mainly in the English and Czech languages. The molecular mechanisms of microbial cryoprotection differ depending on the environment where microorganisms were initially isolated. It was observed that the viability of microorganisms after cryopreservation is dependent on a number of factors, primarily colony age, amount of inoculum, cell size or rate of cooling, and their molecular inventory. Therefore, this paper is devoted to assessing the performance and suitability of various cryopreservation methods of intestinal bacteria, including molecular mechanisms of their protection. In order to successfully complete the cryopreservation process, selecting the correct laboratory equipment and cryopreservation methodology is important. Our analysis revealed that SRB should be stored in glass vials to help mitigate the corrosive nature of hydrogen sulfide, which can affect their physiology on a molecular level. Furthermore, it is recommended that their storage be performed in distilled water or in a suspension with a low salt concentration. From a molecular biological and bioengineering perspective, this contribution emphasizes the need to consider the potential impact associated with SRB in the medical, construction, and environmental sectors.

Abstract
Gut microbiota can be transmitted either environmentally or socially and vertically at intraspecific level; however, whether gut microbiota interact along trophic levels has been largely overlooked. Here, we characterized the gut bacterial communities of weevil larvae of Curculio arakawai that infest acorns of Mongolian oak (Quercus mongolica) as well as acorn-eating mammals, Siberian chipmunk (Tamias sibiricus), to test whether consumption of seed-borne larvae remodels the gut bacterial communities of T. sibiricus. Ingestion of weevil larvae of C. arakawai significantly altered the gut bacterial communities of T. sibiricus. Consequently, T. sibiricus fed larvae of C. arakawai showed higher capability to counter the negative effects of tannins, in terms of body weight maintenance, acorn consumption, N content in feces, urine pH, and blood ALT activity. Our results may first show that seed-borne insects as hidden players have a potential to alter the gut microbiota of seed predators in the tripartite system.
