An indigenous crude extract was used to produce calcite from Canavalia ensiformis and its ability to precipitate calcite with urea and calcium chloride was investigated. X-ray diffraction and scanning electron microscopy were employed to elucidate the mechanism of calcite formation from the plant crude extracts. The results revealed that urease in the plant crude extracts catalyzed the hydrolysis of urea in liquid state cultures. The procedure described herein is a simple method of calcite biomineralization without cultivation of microorganisms or further purification of crude extracts. The unconfined compressive strength of a specimen injected once with Canavalia ensiformis extract showed a 10.6 fold increase when compared to an untreated specimen. In addition, the manufactured plant crude extracts showed significant heavy metal removal efficiency and acidified soil remediation ability in the mine impacted soil. This study showing successful biomineralization of calcite and soil remediation using indigenous Canavalia ensiformis crude extracts without further enzyme purification.
