Abstract

Due to unique genomic adaptations, Methanococcus maripaludis Mic1c10 is highly corrosive when in direct contact with Fe0. A critical adaptation involves increased glycosylation of an extracellular [NiFe]-hydrogenase, facilitating its anchoring to cell surface proteins. Corrosive strains adapt to the constructed environment via horizontal gene transfer while retaining ancestral genes important for intraspecies competition and surface attachment. This calls for a reevaluation of how the built environment impacts methane cycling.

甲烷发生器通过直接接触适应 Fe0 腐蚀。
由于独特的基因组适应性,海洋梅氏球菌 Mic1c10 在与 Fe0 直接接触时具有很强的腐蚀性。一个关键的适应包括增加细胞外[NiFe]-氢化酶的糖基化,促进其与细胞表面蛋白的锚定。腐蚀性菌株通过水平基因转移适应构建环境,同时保留了对种内竞争和表面附着非常重要的祖先基因。这就需要重新评估建筑环境对甲烷循环的影响。

期刊介绍: npj Biofilms and Microbiomes is a comprehensive platform that promotes research on biofilms and microbiomes across various scientific disciplines. The journal facilitates cross-disciplinary discussions to enhance our understanding of the biology, ecology, and communal functions of biofilms, populations, and communities. It also focuses on applications in the medical, environmental, and engineering domains. The scope of the journal encompasses all aspects of the field, ranging from cell-cell communication and single cell interactions to the microbiomes of humans, animals, plants, and natural and built environments. The journal also welcomes research on the virome, phageome, mycome, and fungome. It publishes both applied science and theoretical work. As an open access and interdisciplinary journal, its primary goal is to publish significant scientific advancements in microbial biofilms and microbiomes. The journal enables discussions that span multiple disciplines and contributes to our understanding of the social behavior of microbial biofilm populations and communities, and their impact on life, human health, and the environment.
