Dissolved organic matter (DOM) can be degraded by sunlight into a variety of photoproducts
that stimulate the growth and activity of microorganisms in aquatic environments. All …

The extraction of water soluble extracellular polymeric substances (EPS) from activated
sludge was investigated. The extraction procedure was based upon cation exchange using …

Cellular carbon and nitrogen content and cell volume of nutritionally and morphologically
diverse dinoflagellate species were measured to determine carbon to volume (C: vol) and …

Unialgal cultures were used to investigate relationships between cell volume and the carbon
and nitrogen content of nondiatomaceous marine nanophytoplankton. Cell dimensions were …

In order to better estimate bacterial biomass in marine environments, we developed a novel
technique for direct measurement of carbon and nitrogen contents of natural bacterial …

There has been an explosion of research on marine microbial foodweb processes in the
past decade. Today it is widely accepted that about 50% of the primary production in marine …

We applied transmission electron microscopy and densitometric image analysis to measure
the cell volume (V) and dry weight (DW) of single bacterial cells. The system was applied to …

OCEANIC dissolved organic carbon (DOC) is one of the Earth's largest carbon reservoirs,
but until recently its role in the carbon cycle has been neglected. New methodology1 …

Marine bacterioplankton were isolated and grown in batch cultures until their growth
became limited by organic carbon (C), nitrogen (N), or phosphorus (P). Samples were taken …

Columns were packed with clean quartz sand, sterilized, and inoculated with different strains
of bacteria, which multiplied within the sand at the expense of a continuous supply of fresh …
