説明
A filtering method was applied to confirm the mechanism of bacterial floc formation in seawater. Experimental results showed clearly that the cells of E.coli, either living or non-living, adsorb divalent cations form ionic solutions and seawater.<br> The adsorption value increased with the concentration of ions in solution. However, in the Mg ion solution containing Mg at seawater level, the adsorption capacity decreased owing to the formation of bacterial micelles.<br> On the basis of the experimental results, it is suggested that there exist two processes by which floc formation of E. coli occurs in seawater.<br> In the first process, the bacteria egested or carried into the sea adsorb divalent cations, thereby becoming bridged to ode another with the consequent formation of bacterial micelles.<br> In the second process, the bacterial micelle provide per se space for growth, which is also enhanced by the accumulation or sorption of organic matter dissolved in seawater, thereby giving rise to visible bacterial flocculation.
