Bacteria play a central role in this interplay (Azam and Cho 1987): they contribute to nutrient dynamics, carbon flux, and food web interactions. Potentially, about 40–50% of photosynthetically fixed carbon may be rapidly channeled via dissolved organic carbon (DOC) and the mic

Bacterial Secondary Production,ater column and sediments of freshwater and marine systems, bacteria are thought to be the major decomposers of organic matter (Point and Morris 1982, Azam and Cho 1987, Münster and Chróst 1990, Chróst 1990; Chapter 6, this volume). Nowadays we accept that the production of bacterial biomass represe

Microbial Enzymatic Degradation and Utilization of Organic Matter, heterotrophic microorganisms play a dominant role in the cycling of organic and inorganic matter and that a large fraction of primary production is not consumed directly by herbivorous consumers but is transformed into bacterial biomass (Lovell and Konopka 1985, Chróst and Rai 1993; Chapter 5, this

Usually they grow very well on nutrient agar, from which they can be isolated also. They are widespread throughout the whole biosphere: water, soil, and air. It is doubtful wheth
