Description:	The biochemical methane potential (BMP) index from agricultural, agroindustrial and livestock wastes it is essential for bioreactor?s design and to enable the biogas plants. For BMP standard procedure is necessary to use an inoculum stable, acclimated to the test conditions and adapted to the substrate. In general, inoculum seed from co-digestion biogas plant is used, but this is not practicable in countries like Brazil. This work reports a laboratory case study to produce and maintain a mesophilic anaerobic inoculum for BMP test according VDI 4630. This manuscript suggests a mesophilic acclimation methodology of a mixture made with different inoculum seeds (fresh dairy manure, UASB sludge from swine manure treatment and UASB sludge from food industry). The laboratory acclimated inoculum show efficient biogas yield for cellulose standard. However, in an interlaboratory study, show very similar results for biogas yield and BMP for two reference samples tested.
