Abstract
Aerobic methanotrophic bacteria are considered strict aerobes but are often highly abundant in hypoxic and even anoxic environments. Despite possessing denitrification genes, it remains to be verified whether denitrification contributes to their growth. Here, we show that acidophilic methanotrophs can respire nitrous oxide (N2O) and grow anaerobically on diverse non-methane substrates, including methanol, C-C substrates, and hydrogen. We study two strains that possess N2O reductase genes: Methylocella tundrae T4 and Methylacidiphilum caldifontis IT6. We show that N2O respiration supports growth of Methylacidiphilum caldifontis at an extremely acidic pH of 2.0, exceeding the known physiological pH limits for microbial N2O consumption. Methylocella tundrae simultaneously consumes N2O and CH4 in suboxic conditions, indicating robustness of its N2O reductase activity in the presence of O2. Furthermore, in O2-limiting conditions, the amount of CH4 oxidized per O2 reduced increases when N2O is added, indicating that Methylocella tundrae can direct more O2 towards methane monooxygenase. Thus, our results demonstrate that some methanotrophs can respire N2O independently or simultaneously with O2, which may facilitate their growth and survival in dynamic environments. Such metabolic capability enables these bacteria to simultaneously reduce the release of the key greenhouse gases CO2, CH4, and N2O.

Int Microbiol 2024; 27:607-614.

Abstract
Wetlands are the main natural sources of methane emissions, which make up a significant portion of greenhouse gas emissions. Such wetland patches serve as rich habitats for aerobic methanotrophs. Limited knowledge of methanotrophs from tropical wetlands widens the scope of study from these habitats. In the present study, a freshwater wetland in a tropical region in India was sampled and serially diluted to obtain methanotrophs in culture. This was followed by the isolation of methanotrophs on agarose-containing plates, incubated under methane: air atmosphere. Methanotrophs are difficult to cultivate, and very few cultures of methanotrophs are available from tropical wetlands. Our current study reports the cultivation of a diverse community of methanotrophs from six genera, namely, Methylomonas, Methylococcus, Methylomagnum, Methylocucumis (type I methanotrophs) along with Methylocystis, Methylosinus (type II methanotrophs). A high abundance of methanotrophs (106-1010 methanotrophs/g fresh weight) was observed in the samples. A Methylococcus strain could represent a putative novel species that was also isolated. Cultures of Methylomagnum and Methylocucumis, two newly described type I methanotrophs exclusively found in rice fields, were obtained. A large number of Methylomonas koyamae strains were cultured. Our study is pioneering in the documentation of culturable methanotrophs from a typical tropical wetland patch. The isolated methanotrophs can act as models for studying methanotroph-based methane mitigation from wetland habitats and can be used for various mitigation and valorization applications.

Abstract
An aerobic methanotroph was isolated from a secondary sedimentation tank of a wastewater treatment plant and designated strain OY6T. Cells of OY6T were Gram-stain-negative, pink-pigmented, motile rods and contained an intracytoplasmic membrane structure typical of type I methanotrophs. OY6T could grow at a pH range of 4.5-7.5 (optimum pH 6.5) and at temperatures ranging from 20 °C to 37 °C (optimum 30 °C). The major cellular fatty acids were C14 : 0, C16 : 1ω7c/C16 : 1ω6c and C16 : 1ω5c; the predominant respiratory quinone was MQ-8. The genome size was 5.41 Mbp with a DNA G+C content of 51.7 mol%. OY6T represents a member of the family Methylococcaceae of the class Gammaproteobacteria and displayed 95.74-99.64 % 16S rRNA gene sequence similarity to the type strains of species of the genus Methylomonas. Whole-genome comparisons based on average nucleotide identity (ANI) and digital DNA-DNA hybridisation (dDDH) confirmed that OY6T should be classified as representing a novel species. The most closely related type strain was Methylomonas fluvii EbBT, with 16S rRNA gene sequence similarity, ANI by blast (ANIb), ANI by MUMmer (ANIm) and dDDH values of 99.64, 90.46, 91.92 and 44.5 %, respectively. OY6T possessed genes encoding both the particulate methane monooxygenase enzyme and the soluble methane monooxygenase enzyme. It grew only on methane or methanol as carbon sources. On the basis of phenotypic, genetic and phylogenetic data, strain OY6T represents a novel species within the genus Methylomonas for which the name Methylomonas defluvii sp. nov. is proposed, with strain OY6T (=GDMCC 1.4114T=KCTC 8159T=LMG 33371T) as the type strain.

Abstract
Strain 16-5T, a mesophilic methanotroph of the genus Methylococcus, was isolated from rice field soil sampled in Chungcheong Province, Republic of Korea. Strain 16-5T had both particulate and soluble methane monooxygenases and could only grow on methane and methanol as electron donors. Strain 16-5 T cells are Gram-negative, white to light tan in color, non-motile, non-flagellated, diplococcoid to cocci, and have the typical type I intracytoplasmic membrane system. Strain 16-5T grew at 18-38 °C (optimum, 27 °C) and at pH 5.0-8.0 (optimum, pH 6.5-7.0). C16 : 1 ω7c (38.8%), C16 : 1 ω5c (18.8%), C16 : 1 ω6c (16.8%) and C16 : 0 (16.9%) were the major fatty acids, and phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified phospholipid were the major polar lipids. The main respiratory quinone was methylene-ubiquinone-8. Strain 16-5T displayed the highest 16S rRNA gene sequence similarities to other taxonomically recognized members of the genus Methylococcus, i.e. Methylococcus capsulatus TexasT (98.62%) and Methylococcus geothermalis IM1T (98.49 %), which were its closest relatives. It did, however, differ from all other taxonomically described Methylococcus species due to some phenotypic differences, most notably its inability to grow at temperatures above 38 °C, where other Methylococcus species thrive. Its 4.34 Mbp-sized genome has a DNA G+C content of 62.47 mol%, and multiple genome-based properties such as average nucleotide identity and digital DNA-DNA hybridization value distanced it from its closest relatives. Based on the data presented above, this strain represents the first non-thermotolerant species of the genus Methylococcus. The name Methylococcus mesophilus sp. nov. is proposed, and 16-5T (=JCM 35359T=KCTC 82050T) is the type strain.

Abstract
Wetlands are the major natural source of methane, an important greenhouse gas. The sulfur and methane cycles in wetlands are linked—e.g., a strong sulfur cycle can inhibit methanogenesis. Although there has historically been a clear distinction drawn between methane and sulfur oxidizers, here, we isolated a methanotroph that also performed respiratory oxidization of sulfur compounds. We experimentally demonstrated that thiotrophy and methanotrophy are metabolically compatible, and both metabolisms could be expressed simultaneously in a single microorganism. These findings suggest that mixotrophic methane/sulfur-oxidizing bacteria are a previously overlooked component of environmental methane and sulfur cycles. This creates a framework for a better understanding of these redox cycles in natural and engineered wetlands. Natural and anthropogenic wetlands are major sources of the atmospheric greenhouse gas methane. Methane emissions from wetlands are mitigated by methanotrophic bacteria at the oxic–anoxic interface, a zone of intense redox cycling of carbon, sulfur, and nitrogen compounds. Here, we report on the isolation of an aerobic methanotrophic bacterium, ‘Methylovirgula thiovorans' strain HY1, which possesses metabolic capabilities never before found in any methanotroph. Most notably, strain HY1 is the first bacterium shown to aerobically oxidize both methane and reduced sulfur compounds for growth. Genomic and proteomic analyses showed that soluble methane monooxygenase and XoxF-type alcohol dehydrogenases are responsible for methane and methanol oxidation, respectively. Various pathways for respiratory sulfur oxidation were present, including the Sox–rDsr pathway and the S4I system. Strain HY1 employed the Calvin–Benson–Bassham cycle for CO2 fixation during chemolithoautotrophic growth on reduced sulfur compounds. Proteomic and microrespirometry analyses showed that the metabolic pathways for methane and thiosulfate oxidation were induced in the presence of the respective substrates. Methane and thiosulfate could therefore be independently or simultaneously oxidized. The discovery of this versatile bacterium demonstrates that methanotrophy and thiotrophy are compatible in a single microorganism and underpins the intimate interactions of methane and sulfur cycles in oxic–anoxic interface environments.

Abstract
Remarkably diverse bacteria have been observed as biofilm aggregates on the surface of deep-sea invertebrates that support the growth of hosts through chemosynthetic carbon fixation. Growing evidence also indicates that community-wide interactions, and especially cooperation among symbionts, contribute to overall community productivity. Here, metagenome-guided metatranscriptomic and metabolic analyses were conducted to investigate the taxonomic composition, functions, and potential interactions of symbionts dwelling on the seta of Shinkaia crosnieri lobsters in a methane cold seep. Methylococcales and Thiotrichales dominated the community, followed by the Campylobacteriales, Nitrosococcales, Flavobacteriales, and Chitinophagales Metabolic interactions may be common among the episymbionts since many separate taxon genomes encoded complementary genes within metabolic pathways. Specifically, Thiotrichales could contribute to detoxification of hydroxylamine that is a metabolic by-product of Methylococcales. Further, Nitrosococcales may rely on methanol leaked from Methylococcales cells that efficiently oxidize methane. Elemental sulfur may also serve as a community good that enhances sulfur utilization that benefits the overall community, as evidenced by confocal Raman microscopy. Stable intermediates may connect symbiont metabolic activities in cyclical oxic-hypoxic fluctuating environments, which then enhance overall community functioning. This hypothesis was partially confirmed via in situ experiments. These results highlight the importance of microbe-microbe interactions in symbiosis and deep-sea adaptation. IMPORTANCE Symbioses between chemosynthetic bacteria and marine invertebrates are common in deep-sea chemosynthetic ecosystems and are considered critical foundations for deep-sea colonization. Episymbiotic microorganisms tend to form condensed biofilms that may facilitate metabolite sharing among biofilm populations. However, the prevalence of metabolic interactions among deep-sea episymbionts and their contributions to deep-sea adaptations are not well understood due to sampling and cultivation difficulties associated with deep-sea environments. Here, we investigated metabolic interactions among the episymbionts of Shinkaia crosnieri, a dominant chemosynthetic ecosystem lobster species in the Northwest Pacific Ocean. Meta-omics characterizations were conducted alongside in situ experiments to validate interaction hypotheses. Furthermore, imaging analysis was conducted, including electron microscopy, fluorescent in situ hybridization (FISH), and confocal Raman microscopy (CRM), to provide direct evidence of metabolic interactions. The results support the Black Queen Hypothesis, wherein leaked public goods are shared among cohabitating microorganisms to enhance the overall adaptability of the community via cooperation.

Abstract
The bacterial genus Methylococcus, which comprises aerobic thermotolerant methanotrophic cocci, was described half-a-century ago. Over the years, a member of this genus, Methylococcus capsulatus Bath, has become a major model organism to study genomic and metabolic basis of obligate methanotrophy. High biotechnological potential of fast-growing Methylococcus species, mainly as a promising source of feed protein, has also been recognized. Despite this big research attention, the currently cultured Methylococcus diversity is represented by members of the two species, M. capsulatus and M. geothermalis, while finished genome sequences are available only for two strains of these methanotrophs. This study extends the pool of phenotypically characterized Methylococcus strains with good-quality genome sequences by contributing four novel isolates of these bacteria from activated sludge, landfill cover soil, and freshwater sediments. The determined genome sizes of novel isolates varied between 3.2 and 4.0Mb. As revealed by the phylogenomic analysis, strains IO1, BH, and KN2 affiliate with M. capsulatus, while strain Mc7 may potentially represent a novel species. Highest temperature optima (45-50°C) and highest growth rates in bioreactor cultures (up to 0.3h-1) were recorded for strains obtained from activated sludge. The comparative analysis of all complete genomes of Methylococcus species revealed 4,485 gene clusters. Of these, pan-genome core comprised 2,331 genes (on average 51.9% of each genome), with the accessory genome containing 846 and 1,308 genes in the shell and the cloud, respectively. Independently of the isolation source, all strains of M. capsulatus displayed surprisingly high genome synteny and a striking similarity in gene content. Strain Mc7 from a landfill cover soil differed from other isolates by the high content of mobile genetic elements in the genome and a number of genome-encoded features missing in M. capsulatus, such as sucrose biosynthesis and the ability to scavenge phosphorus and sulfur from the environment.
