Screening of Gold Biomineralization Mechanism in Cyanobacteria

The metal-uptake ability known as biomineralization of microorganisms including fungi, yeasts and bacteria has been known for a long time. This process caused by metal ion stress response from microorganisms offering an efficient way to extract metal in solid state from environment, thus it can be applied in heavy metals bioremediation and precious metal recovery. Since metal biomineralization is the matter of ion stress response from microorganisms and cyanobacteria is one of the most successful organisms on the planet, therefore in this study we try to evaluate the biomineralization potential of cyanobacteria based on their genomes using gold biomineralization as a case study. According to our method we found that there are six cyanobacteria strains which have high potential for gold biomineralization.
