Microbe-mineral interactions in caves can lead to secondary mineral formations such as speleothems, moonmilk etc. In the present review, we provide a summary of geomicrobiological work done so far in some Indian caves. Microbially induced mineralization is documented in cave ecosystems and microbial metabolisms help in mineral formations either through direct/active or indirect/passive processes. Laboratory based experiments conducted on speleothems from Sahastradhara caves (Dehradun); Borra Cave (Andhra Pradesh); Krem Phyllut, Krem Mawsmai, Krem Mawmluh and Rongai Dobhakol (Meghalaya) have clearly demonstrated that bacterial strains isolated from these caves have the capability to precipitate minerals under controlled conditions.
