Abstract: | - Evidence was obtained which supports the hypothesis that thefirm colonies of Nostoc verrucosum, but not the softer onesof N. commune, can accumulate phosphate from the environmentby non-active means.
- This accumulation of phosphate was reducedby pre-treating thecolonies with chelating agents, whilst thepresence of CaCl2in the medium led to an increase.
