Sand is also easy to find from the seaside or river banks. Assuming that the edge structure of the sand particles from stream banks is sharper than that of seaside sand because there is less friction on stream banks. We obtained stream bank sand which, we sieved to 0.5-3 mm in size. Before applying to DNA extraction, we washed the sand with ddH2O
