英文摘要Altering the function of a mixed microbial community through specific microorganisms is a challenge. In this study, we constructed different co-culture systems to not only elucidate the mechanisms of microbial interactions but also explain the significance to the environment. Metagenomic analysis indicated that Methylomonas sp. was the main contributor to aerobic methane oxidation in the soils. Co-culture experiments showed that the introduction of Methylophilus sp. and Rhizobium sp., isolated from rainwater, significantly enhanced aerobic methane oxidation rates, on an hourly scale, representing maximum increases of 50.49 % and 24.62 %, respectively. Furthermore, metatranscriptomic analysis revealed that Methylophilus sp. and Rhizobium sp. could recolonize in the soil with abundance increasing to 1.23 % and 0.02 %. The genes of hxlA (methanol metabolism gene) and cobC (cobalamin synthesis gene) were upregulated, leading to the upregulation of methane oxidation genes such as pmoA and mmoX. The findings uncover the mechanisms of microbial interactions that improve aerobic methane oxidation and highlight the importance of these interactions in maintaining carbon cycle equilibrium in wetlands.
