N2 - Steel is widely used material because of its strength, yet it is easy to corrode. Current steel protection methods require high energy and potentially harmful to living organism. Bacteria are capable to deposit CaCO3, so it can be developed as environmentally friendly anti-corrosion agents. The objectives of this study were to isolate CaCO3-precipitating bacteria from South Malang beach and determine its potential as anti-corrosion agent through CaCO3 precipitation test and its resistance against high calcium levels environment. This study was successfully isolated 12 carbonatogenic bacteria from 3 locations coded GAP A1, GAS A1 and GAS A2 are from Gatra beach; WP1 A1-2, WP1 A2, WP1 A3, WP2 A1, WP2 A2, WP2 A3 and WP2 A5 are originating from Watu Pecah beach; and TW2 A2 is from Tiga Warna beach. The results of the CaCO3 precipitation test showed that all bacterial isolates were able to precipitate CaCO3, but isolates with highest ability were WP1 A2 and WP1 A1-2 with a weight CaCO3 powder are 43.7 mg/100 ml and 42.2 mg/100 ml respectively. Bacterial resistance tests against high calcium concentration showed that isolates WP1 A1-2, WP1 A2, WP1 A3, and GAS 2 were able to grow very well on media containing 200 ppm of CaCl2. This study obtained isolates WP1 A2 and WP1 A1-2 that have the potential to be developed as corrosion inhibitor agents through the CaCO3 coating mechanism.
