Abstract

The formation of calcite and struvite crystals byAzotobacter vinelandii andA.chroococcum was studied on chemically defined media. The crystals were identified microscopically and by X-ray differentiation analysis. Calcite crystal formation was inhibited specifically with 0.05 % ammonium sulfate. However, 0.2 % ammonium sulfate was required for struvite crystal formation.
