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 massPremog kot pomemben vir energije je pogosto predmet študija znanstvenikov s področja kemije, fizike, tehnologije, biologije in drugih ved. Na Kosovu so velike količine premoga v obliki lignita. Največ lignita se uporablja za proizvodnjo električne energije, zato je razumljiv interes kosovske družbe in znanosti za njegovo vsestransko preučevanje. V tem prispevku je predstavljena analiza mikroflore lignita iz rudnika Mirash pri Kastriotu. Z modernimi mikrobiološkimi metodami so bile določene gostota, razvrstitev, morfološke in fiziološke značilnosti bakterij (heterotrofnih, proteolitičnih, alilolitičnih, lipolitičnih in celulitičnih). Istočasno so bile preiskane tudi aerobne bakterije in glive (kvasovke in plesni). Vzorci lignita so bili analizirani in določene so bile fizikalno-kemične lastnosti, kot so: vsebnost pepela, vsebnosti C, O, H, N, S, karbonatov, silikatov in podobnega. Biomasa izolirane mikroflore iz lignita je bila kemijsko analizirana. Najdeno je osupljivo veliko število bakterijske mikroflore in gliv v lignitu in opažena je bila povezava med kemijsko sestavo premoga in biomaso mikrobov. Vsebnosti C, O, N in H so bile približno enake v premogu in v masi bakterijTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
