Deep-biosphere bacteria from ODP Leg 201
|
Marine sediments harbour a considerable part of the living biomass on earth. The microbial communities within these sediments are characterised by low activities and extremely slow growth. Anyhow, increased cell numbers and activities in upper sulfate-methane transition zones (21-40 meter below seafloor) and in lower sulfate-methane transition zones (90 mbsf) demonstrate the presence of active microbial communities within pacific sediments. To get insights how these microbes thrive within their habitat, isolation and characterisation of dominant representives is necessary. Therefore, novel cultivation approaches were applied to contamination-checked sediment samples taken from the Equatorial Pacific and Peru Margin during ODP Leg 201 of JOIDES Resolution in Jan. – Apr. 2002.
