Research Article | Applied and Environmental ScienceSilver and Copper Acute Effects on Membrane Proteins and Impact on Photosynthetic and Respiratory Complexes in BacteriaThe use of metal ions represents a serious threat to the environment and to all living organisms because of the acute toxicity of these ions. Nowadays, silver nanoparticles are one of the most widely used nanoparticles in various industrial and health applications. The antimicrobial effect of nanoparticles is in part related to the released Ag+ ions and their ability to interact with bacterial membranes. Here, we identify,...
Research Article | Applied and Environmental ScienceIdentifying and Predicting Novelty in Microbiome StudiesWe introduce two concepts to quantify the novelty of a microbiome. The first, the microbiome novelty score (MNS), allows identification of microbiomes that are especially different from what is already sequenced. The second, the microbiome attention score (MAS), allows identification of microbiomes that have many close neighbors, implying that considerable scientific attention is devoted to their study. By computing a microbiome focus...
Research Article | Applied and Environmental ScienceMembers of the Genus Methylobacter Are Inferred To Account for the Majority of Aerobic Methane Oxidation in Oxic Soils from a Freshwater WetlandHere we used soil metagenomics and metatranscriptomics to uncover novel members within the genus Methylobacter. We denote these closely related genomes as members of the lineage OWC Methylobacter. Despite the incredibly high microbial diversity in soils, here we present findings that unexpectedly showed that methane cycling was primarily mediated by a single genus for both methane production (“Candidatus...

The yeast Kluyveromyces marxianus grows at high temperatures and on a wide range of carbon sources, making it a promising host for industrial biotechnology to produce renewable chemicals from plant biomass feedstocks. However, major genetic engineering limitations have kept this yeast from replacing the commonly used yeast...
