10.22099/ijstc.2015.2768

Abstract

This study focused on the process of bacterial calcium carbonate (CaCO3) precipitation
(BCCP) in organic soil. Two samples, organic soil and sand, in glass boxes having dimensions
6×6×2 cm were immersed in bacterial medium (Bacillus pasteurii, urea, and CaCl2) for 4 days.
During the treatment period, the samples were treated with urea medium and CaCl2 every 6 h.
Changes in pH values were monitored at different time intervals. At th
