Global warming due to the emissio n of carbon dioxide (CO 2 ) gas, by the anthropogenic sources is a great threat to the environment. A part of this gas is absorbed by so il bacteria as well as aquatic bacteria and it is converted into inso luble calcium carbonate (CaCO 3 ) or calcite. Increased calcite concentration in water and agricultural land creates many problems to the human. In this invest igation, an attempt has been made to carry out some experiments to iso late some bacteria from cow dung, which have both calcite so lubilizat ion and urease activit ies. Isolated bacteria so lubilize calcite due to the secretion of citric acid, oxalic acid and sanazine pigment. All bacterial iso lates were identified by 16S rRNA gene sequencing and phylogenet ic relat ionship among them was also studied by MEGA 6 software.
