Methanobacterium and Desulfotomaculum were identified and quantified from samples
taken from UASB reactors, operating at three different temperatures (45, 55, 65° C),
receiving vinasses from the production of ethanol using sugarcane molasses.
Methanobacterium populations had the following values: 1.5 E03 (45° C), 1.4 E04 (55° C) y
0.46 E02 (65° C) cells/100 mL. For Desulfotomaculum genera, values were 0.02 E02 (45° …
