Coal, as an important source of energy, is very often the subject of study forscientists from the areas of chemistry, physics, technology, and biology, etc. In Kosovo, large deposits of coal, in the form of lignite, can be found. Lignite is mostly used to produce electrical energy; however, the interest of the country of Kosovo is to study many of the aspects of lignite. In this paper an analysis of the microflora of lignite from the mine in the locality of Mirash, near Kastriot, is presented. With modern microbiological methods, the density, assortment, and some of the morphological and physiological characteristics of bacteria (heterotrophic, proteolytic, amilolytics, lypolytic and celulolytic) were determined and aerobic bacteria and fungi (yeasts and moulds) were investigated also. The samples of lignite were analyzed for physic-chemical attributes, for example, a determination of ash, and of C, O, H, N, S, carbonates, silicates, etc. The biomass of the isolated microflora from lignite was submitted for a chemical analysis and an astounding number of bacterial microflora and fungal was found. A composition chemical link between the coal and the microbial biomass was observed: the values of C, O, N, and H were found to be approximately similar in the coal and the bacterial mass.
