www.sciencemag.org SCIENCE VOL 327 5 FEBRUARY 2010 615 COVER A milliliter of seawater. Motile marine bacteria can take advantage of highly heterogeneous landscapes of dissolved organic carbon, resulting from zooplankton excretions (left), leakage by phytoplankton (top) and marine snow particles (bottom), and phytoplankton lysis (right). The Gordon Research Conference on Marine Microbes will be ...
growth medium. Growth was not appreciably affected by the detergents (0.0001 %) except for dodecyl and octadecyl sulfate, which showed some inhibition. It is apparent that enzymatic activity decreases as the number of carbons in the alkyl chain is increased. Equivalent concentrations are without effect on preformed penicillinase. However, the same pattern of inhibition occurred when the deterge...
The ubiquitous SAR11 bacterial clade is the most abundant type of organism in the world's oceans, but the reasons for its success are not fully elucidated. We analysed 128 surface marine metagenomes, including 37 new Antarctic metagenomes. The large size of the data set enabled internal transcribed spacer (ITS) regions to be obtained from the Southern polar region, enabling the first global cha...
