Methanogenic and methanotrophic archaea play important roles in the global flux of methane. Culture-independent approaches are providing deeper insight into diversity evolution methane-metabolizing microorganisms, but, until now, no compelling evidence has existed for methane metabolism outside phylum Euryarchaeota. We performed metagenomic sequencing a deep aquifer, recovering two near-complete genomes belonging to archaeal Bathyarchaeota (formerly known as Miscellaneous Crenarchaeotal...
Abstract Sponges underpin the productivity of coral reefs, yet few their microbial symbionts have been functionally characterised. Here we present an analysis ~1200 metagenome-assembled genomes (MAGs) spanning seven sponge species and 25 phyla. Compared to MAGs derived from reef seawater, sponge-associated were enriched in glycosyl hydrolases targeting components tissue, mucus macroalgae, revealing a critical role for cycling organic matter. Further, visualisation distribution these genes...
Abstract Microbially mediated processes contribute to coral reef resilience yet, despite extensive characterisation of microbial community variation following environmental perturbation, the effect on microbiome function is poorly understood. We undertook metagenomic sequencing sponge, macroalgae and seawater microbiomes from a macroalgae-dominated inshore define their functional potential evaluate seasonal shifts in microbially processes. In total, 125 high-quality metagenome-assembled...
Abstract Anthropogenic CO 2 emissions are causing ocean acidification, which can affect the physiology of marine organisms. Here we assess possible effects acidification on metabolic potential sponge symbionts, inferred by metagenomic analyses microbiomes two species sampled at a shallow volcanic seep and nearby control reef. When comparing microbial functions between sites, microbiome Stylissa flabelliformis (which is more abundant site) exhibits reduced for uptake exogenous carbohydrates...
Abstract Marine bacterioplankton underpin the health and function of coral reefs respond in a rapid sensitive manner to environmental changes that affect reef ecosystem stability. Numerous meta-omics surveys over recent years have documented persistent associations opportunistic seawater microbial taxa, their associated functions, with metrics stress poor (e.g. elevated temperature, nutrient loads macroalgae cover). Through positive feedback mechanisms, disturbance-triggered heterotrophic...
Coal bed methane (CBM) is generated primarily through the microbial degradation of coal. Despite a limited understanding microorganisms responsible for this process, there significant interest in developing methods to stimulate additional production from CBM wells. Physical techniques including hydraulic fracture stimulation are commonly applied wells, however effects specific additives contained fluids on native communities poorly understood. Here, metagenomic sequencing was formation...
Abstract Microbial diversity has been extensively explored in reef-building corals. However, the functional roles of coral-associated microorganisms remain poorly elucidated. Here, we recover 191 bacterial and 10 archaeal metagenome-assembled genomes (MAGs) from coral Acropora kenti (formerly A. tenuis ) adjacent seawater, to identify microbial functions metabolic interactions within holobiont. We show that 82 MAGs were specific holobiont, including members Pseudomonadota, Bacteroidota,...
The sponge microbiome underpins host function through provision and recycling of essential nutrients in a nutrient poor environment. Genomic data suggest that carbohydrate degradation, carbon fixation, nitrogen metabolism, sulphur metabolism supplementation B-vitamins are central microbial functions. However, validation beyond the genomic potential symbiont pathways is rarely explored. To evaluate metagenomic predictions, we sequenced metagenomes metatranscriptomes three common coral reef...
Most marine sponge species harbour distinct communities of microorganisms which contribute to various aspects their host's health and physiology. In addition key roles in nutrient transformations chemical defence, these symbiotic microbes can shape phenotype by mediating important developmental stages influencing the environmental tolerance host. However, characterisation each microbial taxon throughout a sponge's life cycle remains challenging, with several hosting up 3000 species....
As part of a double-blind placebo-controlled study the effects ritanserin on cocaine use and craving, reactivity to cocaine-related events was assessed both before during medication. Twenty-two patients receiving 23 placebo were exposed cues while continuous measures heart rate, skin temperature, resistance taken. Self-reports high, withdrawal, craving also collected. The produced significant physiological responding as well increases in high sessions. Ritanserin reduced cue-elicited...
Abstract Many marine sponges host highly diverse microbiomes that contribute to various aspects of health. Although the putative function individual groups sponge symbionts has been increasingly described, extreme diversity generally precluded in‐depth characterization entire microbiomes, including identification syntrophic partnerships. The Indo‐Pacific Ianthella basta is emerging as a model organism for symbiosis research, hosting only three dominant symbionts: Thaumarchaeotum,...
Abstract Sponge microbiomes are often highly diverse making it difficult to determine which lineages important for maintaining host health and homeostasis. Characterising genomic traits associated with symbiosis can improve our knowledge of have adapted their what functions they might provide. Here we examined five microbial families sponges that previously shown evidence cophylogeny, including Endozoicomonadaceae, Nitrosopumilaceae, Spirochaetaceae, Microtrichaceae Thermoanaerobaculaceae ,...
