The present invention provides for a method of producing a polysaccharide gel comprising: (a) culturing or growing a cyanobacterium or a mixture of cyanobacteria species in a medium under conditions such that the cyanobacterium or the mixture of cyanobacteria species produces a polysaccharide or a mixture of polysaccharides, (b) optionally separating the polysaccharide or the mixture of polysaccharides from the medium and/or the cyanobacterium or the mixture of cyanobacteria species, and (c) increasing the pH of the polysaccharide or the mixture of polysaccharides such that the polysaccharide or the mixture of polysaccharides forms a gel.
