This study characterized anaerobic microorganisms in a granular sludge from a Uasb reactor (Upflow Anaerobic Sludge Blanket) by Most Probable Number (MPN) technique and method of cloning and sequencing the 16S rDNA gene. The main objective of this study was to quantify and to identify the microorganisms in two different culture media containing sulfate (Posgate C 6.0 sodium lactate and 3.13 g L-1 sodium sulfate and Zinder 2.24 sodium lactate and 0.96 g L-1 sodium sulfate). Microorganisms quantified by Postgate C and Zinder media were: 9.30x1010 and 7.50x1011 MPN mL-1 for general anaerobic bacteria; 4.30x108 and 2.10x108 MPN mL-1 for sulfate reducing bacteria; and 1.20x108 and 1.5x108 MPN mL-1 for methane producing archaea, respectively. Bacteria identified by 16S rDNA gene sequencing from the MPN in both culture media were related to the phyla Firmicutes and Proteobacteria. The conditions of Postgate C culture medium favored the sulfate-reducing bacteria and the Zinder culture medium favored the general anaerobic bacteria. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200047 https://www.redalyc.org/journal/3032/303260200047/ https://www.redalyc.org/journal/3032/303260200047/html/ https://www.redalyc.org/journal/3032/303260200047/303260200047.epub https://www.redalyc.org/journal/3032/303260200047/movil https://doi.org/10.4025/actascitechnol.v41i1.39128 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
