Pelagic-benthic coupling of nucleic acids in an abyssal location of the northeastern Atlantic Ocean

Article Abstract:

Pelagic-benthic coupling of nucleic acids is discussed as studied in an abyssal location of the northeastern Atlantic Ocean. Quantitative estimates of DNA distribution and accumulation in deep-sea sediments were made. The DNA fraction studied makes up a pool of potentially refractory DNA that accounts for 16%-40% of the total DNA pool and that may be buried in the sediments. The benthic system was not in a steady state. Temporal changes were significan and mesoscale variability was low.

A method of profiling microbial communities based on a most-probable-number assay that uses BIOLOG plates and multiple sole carbon sources

Article Abstract:

A microbial communities profiling method based on a most-probable-number (MPN) assay using BIOLOG plates and multiple sole carbon sources is discussed. A new approach to the community BIOLOG assay is offered. Cell density of utilizers specific to the carbon source can be estimated.
