“…In addition, harsh environments lead to the downregulation of the gut microbiota and health state in aquaculture organisms [32]. Recently, we found that the supplementation of LAB could improve the gut microbiota, decrease pathogen growth, and promote immunity against infection in white shrimp [33][34][35].…”

In recent years, probiotics have received considerable attention for improving the health of aquaculture organisms, such as fish and shrimp, by stimulating immune activity and increasing growth rates. Oplegnathus fasciatus is a common and economically important cultured fish species in Asia. In this study, we aimed to investigate the potential of lactic acid bacteria (LAB; Limosilactobacillus reuteri)-fermented feed to promote growth and enhance immune function in O. fasciatus. The feed contained the highest proportion of LAB after L. reuteri fermentation for 3 days in anaerobic conditions. Oplegnathus fasciatus was fed LAB-fermented feed for 30 days. The administration of LAB-fermented feed (live bacteria > 109 CFU/g) significantly increased the growth rate (weight gain = 174.8%; FCR = 4.23) and intestinal probiotic levels of O. fasciatus. After LAB-fermented feeding, the immunity index was evaluated by superoxide anion production, the phagocytic activity of leukocytes, and bactericidal and lysozyme activities in the serum of O. fasciatus. We found that LAB-fermented feed treatment potentially elevated the proportions of intestinal Bifidobacterium, Blautia, and Dorea species and reduced pathogenic bacterial growth (Acinetobacter, Escherichia_Shigella, and Megasphaera) in O. fasciatus. This study demonstrated that LAB-fermented feed containing extracellular vesicles improves growth performance and the inhibition of pathogenic Acinetobacter baumannii.

“…The genus Acinetobacter of Proteobacteria was isolated from human specimens, such as human skin or blood ( 51 , 52 ). In the South American samples, the family Legionellaceae of Proteobacteria (Dataset 1, sheet8) was found to be one of the most abundant microbes in the stool of shrimp ( Litopenaeus vannamei ) ( 53 ), and also in the feces of sea cucumbers ( Apostichopus japonicus ) ( 54 ). Some species in the family of Dermatophilaceae of Actinobacteriota were isolated from the skin of chelonids ( 55 ) and the intestinal tracts of fishes ( 56 ).…”

As an important coastal “blue carbon sink,” mangrove ecosystems contain microbial communities with an as-yet-unknown high species diversity. Exploring the assemblage and structure of sediment microbial communities therein can aid in a better understanding of their ecosystem functioning, such as carbon sequestration and other biogeochemical cycles in mangrove wetlands. However, compared to other biomes, the study of mangrove sediment microbiomes is limited, especially in diverse mangrove ecosystems at a large spatial scale, which may harbor microbial communities with distinct compositions and functioning. Here, we analyzed 380 sediment samples from 13 and 8 representative mangrove ecosystems, respectively, in China and South America and compared their microbial features. Although the microbial community compositions exhibited strong distinctions, the community assemblage in the two locations followed analogous patterns: the assemblages of the entire community, abundant taxa, rare taxa, and generalists were predominantly driven by stochastic processes with significant distance-decay patterns, while the assembly of specialists was more likely related to the behaviors of other organisms in or surrounding the mangrove ecosystems. In addition, co-occurrence and topological network analysis of mangrove sediment microbiomes underlined the dominance of sulfate-reducing prokaryotes in both the regions. Moreover, we found that more than 70% of the keystone and hub taxa were sulfate-reducing prokaryotes, implying their important roles in maintaining the linkage and stability of the mangrove sediment microbial communities. This study fills a gap in the large-scale analysis of microbiome features covering distantly located and diverse mangrove ecosystems. Here, we propose a suggestion to the Mangrove Microbiome Initiative that 16S rRNA sequencing protocols should be standardized with a unified primer to facilitate the global-scale analysis of mangrove microbiomes and further comparisons with the reference data sets from other biomes. IMPORTANCE Mangrove wetlands are important ecosystems possessing valuable ecological functions for carbon storage, species diversity maintenance, and coastline stabilization. These functions are greatly driven or supported by microorganisms that make essential contributions to biogeochemical cycles in mangrove ecosystems. The mechanisms governing the microbial community assembly, structure, and functions are vital to microbial ecology but remain unclear. Moreover, studying these mechanisms of mangrove microbiomes at a large spatial scale can provide a more comprehensive insight into their universal features and can help untangle microbial interaction patterns and microbiome functions. In this study, we compared the mangrove microbiomes in a large spatial range and found that the assembly patterns and key functional guilds of the Chinese and South American mangrove microbiomes were analogous. The entire communities exhibited significant distance-decay patterns and were strongly governed by stochastic processes, while the assemblage of specialists may be merely associated with the behaviors of the organisms in mangrove ecosystems. Furthermore, our results highlight the dominance of sulfate-reducing prokaryotes in mangrove microbiomes and their key roles in maintaining the stability of community structure and functions.

“…This has also been observed in shrimp fed a diet enriched with L. fermentum GR-3, in which arsenic levels were diminished by the probiotic [ 44 ]. In general, the aforementioned benefits have also been observed after the inclusion of L. fermentum strains into shrimp diets; namely, lactic acid bacteria did not only ameliorate growth performance and health status but also provided protection against Vibrio parahaemolyticus [ 45 , 46 , 47 ].…”

The implementation of government regulations on antibiotic use, along with the public’s concern for drug resistance, has strengthened interest in developing alternatives not only aimed at preserving animal production but also at reducing the effects of pathogenic infections. Probiotics, in particular, are considered microorganisms that induce health benefits in the host after consumption of adequate amounts; they have been established as a potential strategy for improving growth, especially by stimulating intestinal homeostasis. Probiotics are commonly associated with lactic acid bacteria, and Limosilactobacillus fermentum is a well-studied species recognized for its favorable characteristics, including adhesion to epithelial cells, production of antimicrobial compounds, and activation of receptors that prompt the transcription of immune-associated genes. Recently, this species has been used in animal production. Different studies have shown that the application of L. fermentum strains not only improves the intestinal ecosystem but also reduces the effects caused by potentially pathogenic microorganisms. These studies have also revealed key insights into the mechanisms behind the actions exerted by this probiotic. In this manuscript, we aim to provide a concise overview of the effects of L. fermentum administration on broiler chicken health and performance.
