Protein content and protein synthesis rates of planktonic marine bacteria
Bacterial carbon production is an important parameter in understanding the flows of carbon and energy in aquatic ecosystems, but has been difficult to measure. Present methods are based on measuringExpand

The Ecological Role of Water-Column Microbes in the Sea*
Recently developed techniques for estimating bacterial biomass and productivity indicate that bacterial biomass in the sea is related to phytoplankton concentration and that bacteria utilise 10 to 50Expand

Thymidine incorporation as a measure of heterotrophic bacterioplankton production in marine surface waters: Evaluation and field results
To assess bacterioplankton production in the sea, we have developed a procedure for measuring growth based on incorporation of tritiated thymidine into DNA; the accuracy of this procedure was testedExpand

A simple, economical method for measuring bacterial protein synthesis rates in seawater using 3H-leucine
A simplified method is presented for using 3H-leucine (3H-leu) incorporation to measure bacterial protein synthesis rates in seawater. This method uses small volumes (< 2.0 ml) of seawater andExpand

Intense hydrolytic enzyme activity on marine aggregates and implications for rapid particle dissolution
LARGE, rapidly sinking organic aggregates are an important component of the carbon flux from the ocean's surface to its depths. Marine snow, the main type of large (<0.5 mm) aggregate, is heavilyExpand

Microbial production of recalcitrant dissolved organic matter: long-term carbon storage in the global ocean
The biological pump is a process whereby CO2 in the upper ocean is fixed by primary producers and transported to the deep ocean as sinking biogenic particles or as dissolved organic matter. The fateExpand

The oceanic gel phase: a bridge in the DOM-POM continuum
Recent discoveries reveal that polymer gel particles are abundant and important in the microbial loop, sedimentation processes, biogeochemical cycling, marine carbohydrate chemistry, and particleExpand

Microbial Control of Oceanic Carbon Flux: The Plot Thickens
In his commentary Azam summarizes new work indicating that microbes in the ocean lead much different lives than we had supposed. They ingest both dissolved and particulate carbon and colonizeExpand

Abundance and production of bacteria and viruses in the Bering and Chukchi Seas
The distribution, abundance, and production of viruses and bactena were investigated during an August to September 1992 cruise aboard the RV 'Alpha Helix' in the Bering and Chukchi Seas. Viruses wereExpand
