Microbial Diversity by Substrate Utilization Profiles of Lignite Mines Samples of Gujarat, India
Microbial diversity studies of lignite mines of Rajpardi, Amod, Tadkeshwar and Panandhro, Gujarat, India, were carried out by substrate utilization-based, community-structure analysis. In Biologâ EcoPlates out of 31 different substrates, 1 to 28 substrates were metabolized. On the basis of these, similarity index and diversity indices were studied. From an extreme mine site Gram-positive, Gram-negative, fungi and yeasts were isolated and identified. One of the yeasts isolated is for the first time reported from a lignite mine ecosystem Apart from this auto- and heterotrophic iron oxidizers; sulphur oxidizers and sulphate reducers were also isolated. So, lignite mine ecosystems, inspite of the extreme environment showed rich microbial diversity.
