The net primary production of the biosphere is consumed largely by microorganisms, whose
metabolism creates the trophic base for detrital foodwebs, drives element cycles, and …

We present an overview of the plankton studies conducted during the last 25 years in the
epipelagic offshore waters of the Mediterranean Sea. This quasi-enclosed sea is …

Extracellular enzymes initiate microbial remineralization of organic matter by hydrolyzing
substrates to sizes sufficiently small to be transported across cell membranes. As much of …

Exploring the role of enzymes in biogeochemical processes, this reference explores the
function, molecular biology, and biochemistry of microorganisms and their intra-and extra …

Soft-sediment habitats in intertidal and shallow subtidal marine ecosystems frequently
support extensive populations of benthic microalgae (microphytobenthos). These algal …

A bstract Extracellular enzymes are important agents for microbial foraging and material
cycling in diverse natural and man-made systems. Their abundance and effects are …

Epipelic diatoms are important constituents of estuarine microphytobenthic biofilms. Field‐
based investigations have shown that the production of carbohydrates by such taxa is …

An initial modeling approach was applied to analyze how a single, nonmotile, free-living,
heterotrophic bacterial cell may optimize the deployment of its extracellular enzymes. Free …

The general biochemical role of extracellular enzymes in the sea is similar to that in other
aquatic environments. However, in order to understand the ecological significance of …

We investigated the effect of benthic substratum type (sand and rocks) and nutrient supply
(N and P) on biofilm structure and heterotrophic metabolism in a field experiment in a …
