Coagulation marine algae

Agar-Agar( apanese Gelatin). A yel white mucilaginous substance (hydrophilic polysaccharide) extracted from some marine algae or sea weeds. It is in sol in cold water but sol in hot w, after previous slow swelling (Ref 2). Its aq soln (hydrosol) cannot be easily coagulated by salts (Ref 3)...

The evidence is accumulating that coagulation can be an important process in determining the fate of primary production. The following facts argue for the importance of coagulation of algae in marine ecosystems ... 

Two simulations of the effects of solid-liquid separation are considered here. From, algae to aquifers, these are, first, a consideration of the effects of coagulation on algal populations and sedimenting algal fluxes in marine waters taken from Jackson and Lochmann (28) and, second, evaluation of the effects of deposition or filtration on the transport of particles in groundwater systems taken from Tobiason (29).
