Natural communities of novel archaea and bacteria growing in cold sulfurous springs with a string-of-pearls-like morphology

Article Abstract:

Researchers have discovered a novel bacterial structure in the cold sulfurous Sippenauer Moor near Regensburg, Germany, that grows in the shape of a string of pearls connected by white threads. The pearls are 0.5 to 3.0 mm in diameter and are composed of a filamentous bacterium on the outside and archaeal cocci on the inside. The cocci appear to be embedded in an unknown polymer.

New insights into the lifestyle of the cold-loving SM1 euryarchaeon: Natural growth as a monospecies biofilm in the subsurface

Article Abstract:

A study was conducted on the distribution and origin of the SM1 euryarchaeon and its possible occurrence in the subsurface by the use of situ biofilm trapping system. It was observed that the knowledge of the biology and ecological significance of archaeal in their environments was discovered by the naturally occurring archaeal biofilms.

Thermocrinis ruber gen. nov., sp. nov., a pink-filament-forming hyperthermophilic bacterium isolated from Yellowstone National Park

Article Abstract:

A novel hypothermophilic bacterium isolated from pink filamentous streamers in Octopus Spring in Yellowstone National Park, WY, was characterized. The organisms occurred as single motile rods, as aggregates or as long filaments that formed streamer-like cell masses. The bacterium grew chemolithoautotrophically with hydrogen, thiosulfate and elemental sulfur as electron donors and oxygen as the electron acceptor. It represented a new genus in the order Aquificales, the type species to be named Thermocrinis ruber.
