Summary: Three strains of methanotrophic bacteria were isolated from the River Elbe in Germany, including two novel species within the genus Methylomonas and one member of the species Methylovulum psychrotolerans. These bacteria exhibit differences in carbon source utilization and growth conditions, highlighting the importance of identifying and classifying new species in this study.

Summary: The study found that aerobic methane oxidation in both shallow and deep marine environments is temperature-sensitive, with a positive correlation between methane oxidation rate and temperature. The variations in methane oxidation rates with temperature are related to the different methanotrophic community structures in different marine regions.

Summary: This study prepared biochars with distinctly varying characteristics through iron modification, which proved to be a promising approach to more efficiently improve the three key biochar properties, especially pore volume, and optimize biochar performance. The Fe-modified biochars encouraged a bacterial consortium in the soil, significantly enhancing the CH4 oxidation capacities by up to 26%-74% compared to pristine biochar.

Summary: This study found that natural gas macro-seeps along the Condamine River in eastern Australia significantly increased methane oxidation rates and the abundance of methanotrophs in the surrounding water column, primarily influenced by methane availability and river discharge variation.

Summary: Aquatic ecosystems, such as shallow lakes and wetlands, are important sources of the greenhouse gas methane. This study investigated the effects of phosphorus availability on methane-oxidizing bacterial (MOB) community composition and methane oxidation in sediments from four subtropical lakes. The results showed that increasing phosphate concentrations stimulated methane oxidation and increased bacterial biomass phosphorus content. However, MOB community composition was more strongly correlated with the lake of origin rather than phosphate concentration. These findings suggest that phosphorus can enhance methane oxidation indirectly through increased methane production and directly by promoting MOB growth, but these effects are limited to low phosphate concentrations.

Summary: In this study, a methanol production system was established using methanotroph mutants to control the expression of methanol dehydrogenase (MDH), allowing for methanol accumulation. By modulating the metal ion composition, the conditions for cell growth inhibition and methanol accumulation were repeatedly alternated, showcasing the potential for efficient conversion of methane to methanol.

Summary: The study constructed a genome-scale metabolic model for Methylomicrobium album BG8, highlighting the importance of the ratio between oxygen and methane uptake for optimal growth. The results revealed a coupling between biomass production and carbon dioxide excretion, as well as a trade-off between biomass and acetate production. The integrative model developed in this study will aid in metabolic engineering and the development of a methane bioconversion platform.

Summary: An efficient phase-transfer catalysis system for converting methane to methanol using methanotrophs is reported in this study. The system increases methanol productivity and lowers production costs. The use of a cellulose-membrane reactor system allows for multiple biocatalytic reactions without significant decrease in productivity.
