Horse dung slurry as an optional inoculum selection for anaerobic digestion of food waste

The mechanism of obtaining a reliable estimate of methane potential using an anaerobic bio-digester system is of high importance. The universality of the procedure undertaken to determine the methane production using an anaerobic system is essential to ensure inter-laboratory repeatability and accuracy of the results. Anaerobic sludge from UASB reactors are used as inoculum for seeding in anaerobic digesters. It is challenging to obtain anaerobic sludge with microbial community for startup of the bioreactor. This paper study the specific contribution of the Horse dung slurry inocula methanogenic community for startup reactor. The experimental results obtained discusses the operational parameters for preparation of inoculum from horse dung slurry and its low potential inhibiting effect.
