Nanocomposite of starch-phosphate rock

2018-11-1  To overcome this limitation, a composite was developed based on the dispersion of nanoparticulate phosphate rock in a polysaccharide matrix of starch, as an integrated strategy to facilitate application and provide a supporting substrate for an acidulant microorganism, Aspergillus niger. The bioactivation of the nanocomposite resulted in a remarkable solubilization of up to 70% of the total available phosphate in very low solubility phosphate
