Effect of the tryptone concentration on the calcium carbonate biomineralization mediated by Bacillus cereus

Five tryptone concentrations (0.2%, 0.4%, 0.6%, 0.8% and 1.0%) were evaluated on calcium carbonate biomineralization processes, using 0.5% of calcium acetate. A culture of Bacillus cereus, isolated from the gardens of The Universidad Pontificia Bolivariana (Medellin, Antioquia, Colombia) was used in...
