The archaea that can be readily cultivated in the laboratory are only a small fraction of the total diversity that exists in *** molecular ecology methods,such as metagenomic sequencing,can provide valuable information independent of cell cultivation,it is only through cultivation-based experiments that they may be fully characterized,both for their physiological and ecological ***,we report our efforts towards enriching and isolation of uncultivated archaea from marine sediments using a refined combination of conventional microbial cultivation ***,cells were retrieved from the sediment samples through a cell extraction procedure and the sediment-free mixed cells were then divided into different size-range fractions by successive filtration through 0.8µm,0.6µm and 0.2µm *** 16S rRNA gene analyses indicated noticeable retention of different archaeal groups in different *** each fraction,supplementation with a variety of defined substrates(e.g.,methane,sulfate,and lignin)and stepwise dilutions led to highly active enrichment cultures of several archaeal groups with Bathyarchaeota most prominently ***,using a roll-bottle technique,three co-cultures consisting of Bathyarchaeota(subgroup-8)and a bacterial species affiliated with either Pseudomonas or Glutamicibacter were *** results demonstrate that a combination of cell extraction,size fractionation,and roll-bottle isolation methods could be a useful protocol for the successful enrichment and isolation of numerous slow-growing archaeal groups from marine sediments.
