Biofilms are a form of collective life with emergent properties that confer many advantages on their inhabitants, and they represent a much higher level of organization than single cells do. However, to date, no global analysis on biofilm abundance exists. We offer a critical discussion of the definition of biofilms and compile current estimates of global cell numbers in major microbial habitats, mindful of the associated uncertainty. Most bacteria and archaea on Earth (1.2 × 1030 cells) exist… Expand

Microbial Diversity and Function in Shallow Subsurface Sediment and Oceanic Lithosphere of the Atlantis Massif
TLDR
Overall, this study reveals that the shallow subsurface of an oceanic core complex hosts a biosphere that is not fueled by active serpentinization reactions and by-products, and the capacity for microorganisms to utilize organic carbon was the most prevalent form of carbon cycling. Expand
Mineral-hosted biofilm communities in the continental deep subsurface, Deep Mine Microbial Observatory, SD, USA.
TLDR
It is suggested that host rock mineralogy is an important ecological driver in deep continental biospheres because it can significantly enhance biofilm cell densities and promote selective colonization by taxa putatively capable of extracellular electron transfer. Expand
A global perspective on microbial diversity in the terrestrial deep subsurface
TLDR
The diversity of bacterial communities in deep subsurface groundwater is shown to be controlled by aquifer lithology globally, by using 16S rRNA gene datasets collected across five countries on two continents and from fifteen rock types over the past decade. Expand
The (Un)Natural History of the “Plastisphere,” A New Marine Ecosystem
The presence of a microbial biofilm on marine plastic was described in the pages of Science Magazine over 45 years ago in one of the very first publications reporting plastic in the ocean (CarpenterExpand
Rock-Hosted Subsurface Biofilms: Mineral Selectivity Drives Hotspots for Intraterrestrial Life
TLDR
Through hotspot analysis and spatial modeling approaches, it is found that mineral distributions, particularly those putatively metabolized by microbes, indeed drive biofilm distribution at DeMMO, and that bioleaching of pyrite may be a volumetrically important process influencing fluid geochemistry at this site when considered at the kilometer scale.

Why are nematodes so successful extremophiles?

TLDR
It is proposed that a unique combination of several characteristics of nematodes may explain, additively or synergistically, their successful adaptation to extreme habitats. Expand
We Are One: Multispecies Metabolism of a Biofilm Consortium and Their Treatment Strategies
TLDR
The interspecies communications, including their metabolic cross-talking, in multispecies biofilm are reviewed, to signify the importance of such interactions on the initial formation and subsequent growth of these biofilms. Expand
Rock Surface Fungi in Deep Continental Biosphere—Exploration of Microbial Community Formation with Subsurface In Situ Biofilm Trap
TLDR
The first observations of active fungal colonization of mica schist in the deep continental biosphere and the ability of deep subsurface fungi to attach to rock surfaces under in situ conditions in groundwater are reported. Expand
A New Frontier for Palaeobiology: Earth's Vast Deep Biosphere

  • 2019
TLDR
It is concluded that the fossil record of Earth's largest microbial habitat may still have much to tell us about the history of life, the evolution of biogeochemical cycles, and the search for life on Mars. Expand
The Ecology of Subaerial Biofilms in Dry and Inhospitable Terrestrial Environments
TLDR
Using life on air-exposed minerals as a model and taking inspiration from the mechanisms of some microorganisms that have adapted to inhospitable conditions, the ecology of SABs inhabiting natural and built environments is illustrated. Expand

Towards a better quantitative assessment of the relevance of deep-sea viruses, Bacteria and Archaea in the functioning of the ocean seafloor
TLDR
It is reported that the microbial abundance in the top 50 cm of deep-sea sediments of the world oceans is on the order of 1.5 ± 0.4 Pg C, and the hypothesis that the role of Archaea and viruses could be more relevant in the deepest part of the ocean floor is supported. Expand
Archaeal biofilms: widespread and complex.
TLDR
The present review summarizes and discusses the present investigations of biofilm-forming archaeal species, their diverse biofilm architectures in monospecies or mixed communities, the identified EPSs (extracellular polymeric substances), Archaeal structures mediating surface adhesion or cell-cell connections, and the response to physical and chemical stressors implying thatArchaeal biofilm formation is an adaptive reaction to changing environmental conditions.
