Biologic systems communication

Biocatalysis Chemical reactions mediated by biological systems (microbial communities, whole organisms or cells, cell-free extracts, or purified enzymes aka catalytic proteins). 

WAS Waste activated sludge, mg/L. The excess growth of microorganisms which must be removed from the process to keep the biological system in balance. Wastewater The used water and solids from a community that flow to a treatment plant. Storm water, surface water, and groundwater infiltration also may be included in the wastewater that enters a wastewater treatment plant. The term "sewage" usually refers to household wastes, but this word is being replaced by the term "wastewater".

Tn previous communications (7, 9, 10, H, 12) from this laboratory results have been presented on association reactions between long-chain ionic and long-chain polar compounds. The results have implications regarding the properties of interfaces, including those present in certain biological systems. The latter aspects have been emphasized by Schulman and Rideal (22). 

Marine communities are complicated biological systems of populations of individual species. As a result of their interaction, communities are in dynamic development. Their spatial structure is mostly determined by the composition of numerous biotic and abiotic factors, which depend on the totality of oceanic parameters. The latter are determined by the laws of general circulation of ocean waters, including tides and ebbs, zones of convergence and divergence, wind, and thermohaline currents. 

Homeostasis An inherent tendency in an organ toward maintaining physical and psychologic stability the maintenance of constancy within a biologic system either in terms of interaction between the organisms of a community or between the internal environment of an organism or individual.
