The utilization of methane, a potent greenhouse gas, is an important component local and global carbon cycles that characterized by tight linkages between methane-utilizing (methanotrophic) nonmethanotrophic bacteria. It has been suggested the methanotroph sustains these nonmethanotrophs cross-feeding, because subsequent products methane oxidation pathway, such as methanol, represent alternative sources. We established cocultures in microcosm model system to determine mechanism substrate...
We focused on the functional guild of methane oxidizing bacteria (MOB) as model organisms to get deeper insights into microbial biogeography. The pmoA gene was used a and phylogenetic marker for MOB in two approaches: (i) database (> 4000 sequences) evaluated obtain diversity Italian rice paddies, paddy fields worldwide. results show wide geographical distribution genotypes that seem be specifically adapted (e.g. Rice Paddy Cluster 1 2). (ii) On smaller scale, we designed factorial...
In lake ecosystems a major proportion of methane (CH4) emissions originate from the littoral zone, which can have great spatial variability in hydrology, soil quality and vegetation. Hitherto, heterogeneity effects it has on functioning diversity methanotrophs wetlands been poorly understood. A diagnostic microarray based particulate monooxygenase gene coupled with geostatistics was used to analyse patterns wetland eutrophic boreal (Lake Kevätön, Eastern Finland). The had hydrology gradient...
Abstract Microbial methane-consuming communities significantly impact biogeochemical processes and greenhouse gas emissions. In this study we explored secondary metabolites produced by methane-oxidizing bacteria (MOB) their ecological roles. We analyzed volatile profiles of four MOB strains under controlled conditions conducted a meta-analysis using high-quality genomes from 62 cultured 289 metagenome-assembled to investigate potential for producing metabolites. Results show species-specific...
Alternate prolonged drought and heavy rainfall is predicted to intensify with global warming. Desiccation-rewetting events alter the soil quality nutrient concentrations which drive microbial-mediated processes, including methane oxidation, a key biogeochemical process catalyzed by methanotrophic bacteria. Although aerobic methanotrophs showed remarkable resilience suite of physical disturbances induced as single event, their recurring less known. Here, using rice field in microcosm study,...
The role of microbial diversity for ecosystem functioning has become an important subject in ecology. Recent work indicates that communities and processes can be very sensitive to anthropogenic disturbances. However, what extent may change upon, resist to, or overcome disturbances might differ depending on substrate availability. We used soil from Italian rice field gradient microcosms, analysed the response methanotrophic NH4 (+) pulse as a potential disturbance under two different CH4...
In this perspective article, we question how well model organisms, the ones that are easy to cultivate in laboratory and show robust growth biomass accumulation, reflect dynamics interactions of microbial communities observed nature. Today's -omics toolbox allows assessing genomic potential microbes natural environments a high-throughput fashion at strain-level resolution. However, understanding details activities mechanistic bases community function still requires experimental validation...
ABSTRACT With the advent of molecular biological techniques, especially next-generation sequencing and metagenomics, number microbial biogeography studies is rapidly increasing. However, these involve synthesis data generated by different laboratories using protocols, chemicals, etc., all with inherent biases. The aim this study was to assess inter- as well intralaboratory variations in community composition when standardized protocols are applied a single soil sample. Aliquots from...
Aerobic methanotrophs are crucial in ombrotrophic peatlands, driving the methane and nitrogen cycles. Peat mining adversely affects methanotrophs, but activity community composition/abundances may recover after restoration. Considering that methanotrophic growth significantly stimulated presence of other microorganisms, methane-driven interaction network, encompassing non-methanotrophs (i.e., interactome), also be relevant conferring resilience. Yet, little is known response recovery...
Iron- and methane-cycling are important processes in wetlands with one connected to plant growth the other greenhouse gas emission, respectively. In contrast acidic habitats, there is scarce information on ecology of microbes oxidizing ferrous iron at circum-neutral pH. The latter mainly due lack isolated representatives molecular detection techniques. Recently, we developed PCR-DGGE QPCR assays detect enumerate Gallionella-related neutrophilic iron-oxidisers (FeOB) enabling assessment...
Microbial communities display a variety of biogeographical patterns mainly driven by large-scale environmental gradients. Here, we analysed the spatial distribution methane-oxidizing bacteria (MOB) and methane oxidation in strongly fluctuating environment. We investigated whether variability MOB community can be explained an gradient this changes with different plot sizes. applied pmoA-specific microarray to detect MOB, measured oxidation, emissions soil properties. All variables were 10 ×...
The discovery of the lanthanide requiring enzymes in microbes was a significant scientific that opened whole new avenue biotechnological research this important group metals. However, ecological impact lanthanides on microbial communities utilizing methane (CH 4 ) remains largely unexplored. In study, laboratory microcosm model experiment performed using rice field soils with different pH origins (5.76, 7.2, and 8.36) concentrations La 3+ form lanthanum chloride (LaCl 3 ). Results clearly...
Abstract The presence of phylogenetic signal is assumed to be ubiquitous. However, for microorganisms, this may not true given that they display high physiological flexibility and have fast regeneration. This result in fundamentally different patterns resemblance, is, variable strength signal. microbiological inferences, trait similarities therewith microbial interactions with its environment are mostly follow evolutionary relatedness. Here, we tested whether indeed a straightforward...
The restoration of peatlands is an important strategy to counteract subsidence and loss biodiversity. However, responses microbial soil processes are poorly understood. We assessed functioning, diversity spatial organization methanotrophic communities in drained rewetted peat meadows with different water table management agricultural practice. Results show that the was similar between sites a remarkable dominance genus Methylocystis. Enzyme kinetics depicted no major differences, indicating...
