[PDF] CALCITE-FORMING BACTERIA LOCATED IN …

Calcite-forming by bacteria has been reported in various geological environments including limestone caves, and soil. There are four natural processes by which calcite is formed: carbonic anhydrase (CA), sulphate reduction, nitrate reduction, and urea hydrolysis. The aim of study is to identify calcite-forming bacteria occurring in limestone areas of Malaysia. Ten bacilli were identified to ...

How does weathering affect limestone?

Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

Limestone

In addition, limestone per se cannot form in areas where there is a high influx of terrigenous clastics. Rapid rates of influx of pebble-, cobble-, sand-, silt-, and clay-sized material both adversely affect carbonate-secreting organisms and "mask" any resulting carbonate sediments, producing instead carbonate-rich conglomerate, sandstone, and mudrock.
