Effects of inoculum to substrate ratio, substrate mix ratio and inoculum source on batch co-digestion of grass and pig manure
S Dechrugsa, D Kantachote, S Chaiprapat - Bioresource Technology, 2013 - Elsevier
Biochemical methane potential (BMP) assay was conducted at 35° C to evaluate the effects
of inoculum to substrate ratio (ISR) and substrate mix ratio between para-grass and pig
manure co-digesting using different inocula. Rubber latex digester (RLD) inoculum showed
higher methanogenic activity (41.4 mL CH 4/gVS) than pig farm digester (PFD) inoculum
(37.3 mL CH 4/gVS). However, the maximum methane yields, occurred at the highest para-
grass mix ratio (G), were 369.6, 437.6, 465.9 and 442.6 mL CH 4/gTS added for RLD …
