Microbial life in the deep subsurface biosphere is taxonomically and metabolically diverse,
but it is vigorously debated whether the resident organisms are thriving (metabolizing, …

Microbial ecology within oligotrophic marine sediment is poorly understood, yet is critical for
understanding geochemical cycles. Here, 16S rRNA sequences from RNA and DNA inform …

High-throughput RNA sequencing offers broad opportunities to explore the Earth RNA
virome. Mining 5,150 diverse metatranscriptomes uncovered >2.5 million RNA virus contigs. …

Earth’s subsurface environment is one of the largest, yet least studied, biomes on Earth, and
many questions remain regarding what microorganisms are indigenous to the subsurface. …

Globally, marine sediments are a vast repository of organic matter, which is degraded through
various microbial pathways, including polymer hydrolysis and monomer fermentation. The …

Rising CO 2 concentration in the atmosphere, global climate change, and the sustainability
of the Earth's biosphere are great societal concerns for the 21st century. Global climate …

General studies on benthic microbial communities focus on fundamental biogeochemical
processes or the most abundant constituents. Thereby, minor fractions such as the …

Perchlorate is widely used as an oxidant in solid rocket propellants and energetic applications,
and it has frequently been detected in groundwaters at concentrations relevant to human …

The vast marine deep biosphere consists of microbial habitats within sediment, pore waters,
upper basaltic crust and the fluids that circulate throughout it. A wide range of temperature, …

The accurate and precise measurement of total sulfide has been of major interest for well
over a century. The most commonly used method involves the formation of a methylene blue–…
