Physiological and Biochemical Aspects of Marine Bacteria,ture indirectly important to questions of marine bacterial physiology and biochemstry. In this paper I want to call attention to the contributions physiological and biochemical studies of pure cultures have made to marine ecology.

Dynamics of Pools of Dissolved Organic Carbon,ears our understanding of this process has improved greatly. This paper will explore the interaction of bacteria and dissolved organic matter from an ecological viewpoint. In energy flow terms, the DOM (dissolved organic matter) of natural waters can be construed as a trophic level, the base of a fo

Sinking of Particulate Matter from the Surface Water of the Ocean,cesses of removal. Thus, the amount of organic matter available for utilization within the water column can be calculated as the difference between phytoplankton net production and the loss of particulate organic matter by gravitational settling. Advective loss is assumed to be balanced by advective

Measurement of Bacterioplankton Growth in the Sea and Its Regulation by Environmental Conditions,that bacteria play a quantitatively significant role in the flow of energy and matter in marine ecosystems. The central theme of this “new view” is based on two lines of evidence: (1) bacterial biomass is a significant part of the total biomass in the oceans (Hobbie et al. 1977), and (2) the bacteri

Measurements of Bacterial Growth Rates in some Marine Systems Using the Incorporation of Tritiated ems. In quantifying their role, measurement of the growth rate of the whole bacterial population is necessary, but has proved difficult. A number of different methods have been proposed for measuring microbial growth rates, but many are not specific for bacteria or do not include the whole populatio

Bacterial Growth in Relation to Phytoplankton Primary Production and Extracellular Release of Organf the produced organic matter. Present understanding of the interactions between autotrophic and heterotrophic organisms suffers from limited knowledge of the secondary production. One major problem is the part played by bacteria in returning dissolved organic carbon to organic particles which can b

Diel and Seasonal Variation in Growth Rates of Pelagic Bacteria,, growth rates of natural bacteria have become essential information (Pomeroy 1974; Williams 1981). During the last few years several methods to measure growth of bacteria have been developed (Christian et al. 1982; Fuhrman and Azam 1982; Hagstr?m et al. 1979; Moriarty and Pollard 1981; Sieburth et
