“…Metagenomic study and GeoChip-based analysis of mangrove associated microbiome have provided a snapshot of microbial functional composition and geographical distribution in some specific areas (8,36), but the data are limited. Key functional gene categories in mangrove microbial communities mainly involved carbon fixation, carbon degradation, methane generation, nitrogen fixation, nitrification, denitrification, ammonification, nitrogen reduction, sulfur metabolism, metal resistance, antibiotic resistance, and organic contaminant degradation (1,8). The biochemical transformation functions of the mangrove microbiome in carbon, nitrogen, and sulfur have mostly been recorded in the Yunxiao mangrove and Brazilian mangroves (1,2,10).…”

Mangroves, as important and special ecosystems, create unique ecological environments for examining the microbial gene capacity and potential for producing bioactive compounds. However, little is known about the biogeochemical implications of microbiomes in mangrove ecosystems, especially the variations between pristine and anthropogenic mangroves. To elucidate this, we investigated the microbial taxonomic and functional shifts of the mangrove microbiomes and their potential for bioactive compounds in two different coastal mangrove ecosystems in southern China. A gene catalogue, including 87 million unique genes, was constructed, based on deep shotgun metagenomic sequencing. Differentially enriched bacterial and archaeal taxa between pristine mangroves (Guangxi) and anthropogenic mangroves (Shenzhen) were found. The Nitrospira and ammonia-oxidizing archaea, specifically, were more abundant in Shenzhen mangroves, while sulfate-reducing bacteria and methanogens were more abundant in Guangxi mangroves. The results of functional analysis were consistent with the taxonomic results, indicating that the Shenzhen mangrove microbiome has a higher abundance of genes involved in nitrogen metabolism while the Guangxi mangrove microbiome has a higher capacity for sulfur metabolism and methanogenesis. Biosynthetic gene clusters were identified in the metagenome data and in hundreds of de novo reconstructed nonredundant microbial genomes, respectively. Notably, we found different biosynthetic potential in different taxa, and we identified three high quality and novel Acidobacteria genomes with a large number of BGCs. In total, 67,278 unique genes were annotated with antibiotic resistance, indicating the prevalence and persistence in multidrug-resistant genes in the mangrove microbiome. IMPORTANCE This study comprehensively described the taxonomy and functionality of mangrove microbiomes, including their capacity for secondary metabolite biosynthesis and their ability to resist antibiotics. The microbial taxonomic and functional characteristics differed between geographical locations, corresponding to the environmental condition of two diverse mangrove regions. A large number of microbial biosynthetic gene clusters encoding novel bioactivities were found, and this can serve as a valuable resource to guide novel bioactive compound discovery for potential clinical uses.

“…These fractions had an increase in DNA after 13CH4 addition, corresponding to the microorganisms that incorporated carbon from 13CH4. Interesting to note is that light fractions of the flask incubated with 13CH4 (T2 13C [13][14][15][16][17] representing microorganisms that did not incorporated carbon from 13CH4, formed a cluster with 78% similarity with the inoculum.…”

“…Brazilian mangroves, considered very vulnerable to damage, correspond to 7 to 8.5% of global mangrove areas and it is discontinuously distributed along the Brazilian coast [15]. Previous studies with Brazilian mangrove samples confirmed the presence of methanogenic archaea and metagenomic analysis showed sulfur metabolism prevalent in microbiomes of polluted and pristine sites [2,16,17]. Mesocosm experiments detected changes in bacterial communities induced by oil contamination in mangrove sediments from São Paulo State [18] and reported a preferential enrichment of the aerobic methanotroph Methylococcaeae sequences in the rhizosphere of Rhizophora mangle from Guanabara Bay mangrove, in Rio de Janeiro State [1].…”

Methanotrophic bacteria can use methane as sole carbon and energy source. Its importance in the environment is related to the mitigation of methane emissions from soil and water to the atmosphere. Brazilian mangroves are highly productive, have potential to methane production, and it is inferred that methanotrophic community is of great importance for this ecosystem. The scope of this study was to investigate the functional and taxonomic diversity of methanotrophic bacteria present in the anthropogenic impacted sediments from Bertioga mangrove (SP, Brazil). Sediment sample was cultivated with methane and the microbiota actively involved in methane oxidation was identified by DNA-based stable isotope probing (DNA-SIP) using methane as a labeled substrate. After 4 days of incubation and consumption of 0.7 mmol of methane, the most active microorganisms were related to methanotrophs Methylomonas and Methylobacter as well as to methylotrophic Methylotenera, indicating a possible association of these bacterial groups within a methane derived food chain in the Bertioga mangrove. The abundance of genera Methylomonas, able to couple methane oxidation to nitrate reduction, may indicate that under low dissolved oxygen tensions some aerobic methanotrophs could shift to intraerobic methane oxidation to avoid oxygen starvation.

Photoautotrophic microorganisms, such as microalgae and cyanobacteria, are known to perform an essential role in ecological functions. Besides, they are considered cell factories, producing various bioproducts of commercial interest. In mangroves, these microorganisms are primarily responsible for the ecosystem's high productivity. Moreover, the unique natural characteristics of mangroves, coupled with the intense pressure from anthropic activities that these ecosystems typically experience, make mangrove photoautotrophic microbiota biotechnologically attractive. In this work, the ecological role and biotechnological potential of photoautotrophic mangrove microorganisms worldwide were evaluated, highlighting, their ecosystem services and bioproducts with environmental and commercial appeal, as well as their strategic and technological application through patent analysis.
