Lonar lake, the only basaltic lake in India 19°58’ N & 76°31’ E from Lonar, Buldhana district of Maharashtra India, with alkaline and saline water. The diameter of the lake is 1.8 km and 137m deep which is found to be changing due to environmental changes and human intervention. This observation gave path to study the physicochemical parameters which ultimately might affect the uniqueness and biodiversity of the lake. In the present study isolation of pigmented bacteria (pigments being versatile bioactive secondary metabolites hence emphasized) and physicochemical parameters of ground water sample analysis and was carried out. Out of all microbial isolates, 14 pigment producing bacteria were identified at molecular level, with pH 9.4 the lake water was highly alkaline-(11845 mg/L) and characterised by high concentrations of chlorides (7450 mg/L), nitrates (138 mg/L) and sulphates (117 mg/L). The pigmented microbial community and physicochemical parameters were compared with the previously recorded data which significantly concludes that there is a need to conserve the world’s only one meteorite impact crater in India with its uniqueness.
