“…In addition, we found that based on the downscaling analysis and cluster analysis of bacterial and fungal communities, it all reflected that the bacterial community structure showed typical geographical characteristics with continental boundaries, while the fungal communities had no obvious geographical pattern, consistent with previous work (Xing et al, 2021). Microorganisms detected in cigar tobacco are involved in many fermentation-related stages, Staphylococcus, Corynebacterium, and Oceanobacillus were proved to have a positive effect on fermented products (Jia et al, 2021;Dias et al, 2022;Gao et al, 2022;Liu et al, 2022;Mhatre et al, 2022;Zhou et al, 2022;Li et al, 2023), Corynebacterium and Oceanobacillus also had alkaline resistance, which may be the reason why it could be the representative genus in fermentation (Hirota et al, 2013;Pang et al, 2020), which was related to the changes of aroma substances in cigar leaves after fermentation. The inter-microbial association networks on cigars were also vital to the quality of tobacco (Zheng et al, 2022b).…”

Cigar is made of a typical fermented tobacco where the microbiota inhabits within an alkaline environment. Our current understanding on cigar fermentation is far from thorough. This work employed both high-throughput sequencing and chromatography-mass spectrometric technologies to provide new scientific reference for this specific fermented system. Typical cigar samples from different regions (the Caribbeans, South America, East Asia, and Southeast Asia) were investigated. The results show that Firmicutes, Actinobacteria, Proteobacteria, Ascomycota, and Basidiomycota were the predominant phyla in the cigar samples. Rather than the fungal community, it was the bacterial community structures that played vital roles to differentiate the cigar from different regions: Staphylococcus was the dominant genus in the Americas; Bacillus was the dominant genus in Southeast Asia; while in East Asia, there was no dominant genus. Such differences in community structure then affected the microflora metabolism. The correlation between microbiota and metabolites revealed that Aspergillaceae, Cercospora, and Staphylococcus were significantly correlated with sclareolide; Bacillus were positively associated with isophorone. Alcaligenaceae was significantly and positively correlated with L-nicotine and hexadecanoic acid, methyl ester.GRAPHICAL ABSTRACT

“…Corynebacterium freneyi is closely related to C. xerosis ( Renaud et al, 2001 ). Corynebacterium pollutisoli is an alkali-tolerant bacterium that utilizes anaerobic alkaline fermentation that augments nitrogen removal and converts proteins and carbohydrates into volatile fatty acids (VFAs), which helps solubilize waste sludge and solids ( Liu et al, 2018 ; Pang et al, 2020 ). Its presence would be beneficial to a dairy microbial community for waste remediation processes.…”

BackgroundFundamental investigations into the location, load, and persistence of microbes, whether beneficial or detrimental, are scarce. Many questions about the retention and survival of microbes on various surfaces, as well as the load necessary for spread, exist. To answer these questions, we must know more about where to find various microbes and in what concentrations, the composition of the microbial communities, and the extent of dissemination between various elements. This study investigated the diversity, composition, and relative abundance of the communities associated with manure, lagoons, troughs, house flies, and stable flies present at a dairy, implementing two different free-stall management systems: flow-through and cross-vent. Shotgun metagenomics at the community level was used to compare the microbiomes within the dairy, allowing confident interpretation at the species level.ResultsThe results showed that there were significant difference in microbial composition between not only each of the dairy elements but also management styles. The primary exceptions were the microbiomes of the house fly and the stable fly. Their compositions heavily overlapped with one another, but interestingly, not with the other components sampled. Additionally, both species of flies carried more pathogens than the other elements of the dairy, indicating that they may not share these organisms with the other components, or that the environments offered by the other components are unsatisfactory for the survival of some pathogens..ConclusionThe lack of overlapping pathogen profiles suggests a lack of transfer from flies to other dairy elements. Dairy health data, showing a low incidence of disease, suggests minimal sharing of bacteria by the flies at a level required for infection, given the health program of this dairy. While flies did carry a multitude of pathogenic bacteria, the mere presence of the bacteria associated with the flies did not necessarily translate into high risk leading to morbidity and mortality at this dairy. Thus, using flies as the sole sentinel of dairy health may not be appropriate for all bacterial pathogens or dairies.

“…possess chitinolytic activities [ 22 , 47 , 50 , 51 , 52 , 53 , 54 ] and have been used for chitin extraction [ 55 , 56 ]. Highly abundant Clostridia Tissierella (2%) and Lactobacillales Vagococcus are known fermenters [ 57 , 58 , 59 , 60 ]. Tissierella was also identified as one of the most connected taxa in network interaction, which underlined the importance of this bacteria in shell degradation.…”

Soil microbes play an essential role in the biodegradation of crustacean shells, which is the process of sustainable bioconversion to chitin derivatives ultimately resulting in the promotion of plant growth properties. While a number of microorganisms with chitinolytic properties have been characterized, little is known about the microbial taxa that participate in this process either by active chitin degradation or by facilitation of this activity through nutritional cooperation and composting with the chitinolytic microorganisms. In this study, we evaluated the transformation of the soil microbiome triggered by close approximation to the green crab shell surface. Our data indicate that the microbial community associated with green crab shell matter undergoes significant specialized changes, which was reflected in a decreased fungal and bacterial Shannon diversity and evenness and in a dramatic alteration in the community composition. The relative abundance of several bacterial and fungal genera including bacteria Flavobacterium, Clostridium, Pseudomonas, and Sanguibacter and fungi Mortierella, Mycochlamys, and Talaromyces were increased with approximation to the shell surface. Association with the shell triggered significant changes in microbial cooperation that incorporate microorganisms that were previously reported to be involved in chitin degradation as well as ones with no reported chitinolytic activity. Our study indicates that the biodegradation of crab shells in soil incorporates a consortium of microorganisms that might provide a more efficient way for bioconversion.
