A manned exobiology laboratory based on the Moon [PDF]

open access: yes, 1992
Establishment of an exobiology laboratory on the Moon would provide a unique opportunity for exploration of extraterrestrial materials on a long-term, ongoing basis, for elucidation of exobiological processes and chemical evolution.

Lipid biomarkers reveal dominance of aerobic methanotrophy in a continental serpentinizing system

open access: yesFrontiers in Microbiology
Sources and sinks of methane within an advanced serpentinization-influenced system were investigated at the Coast Range Ophiolite Microbial Observatory (CROMO) in Lower Lake, California. Subsurface water-rock reactions at CROMO contribute to unique, high

Endolithic microbial model for Martian exobiology: The road to extinction [PDF]

open access: yes, 1991
Martian exobiology is based on the assumption that on early Mars, liquid water was present and that conditions were suitable for the evolution of life. The cause for life to disappear from the surface and the recognizable fingerprints of past microbial ...

First record of multicellular filamentous benthic bacteria from freshwater lagoons in central Chile

open access: yesGayana
Observations on “macrobacteria” inhabiting the reduced bottoms of two freshwater lagoons in central Chile are here presented. The new finding of morphologically diverse, colorless multicellular filamentous bacteria expands their known presence into ...
