The pharmaceutical industry is expanding at a rapid pace which will likely to positively impact the buffering agents market. The agent which active against gram positive & gram negative micro-organism which causes degradation of pharmaceutical preparation. Thus, the low methane production in the configuration without buffering agent (AIS + FW) and acidification of the medium (final pH of 5.38) can be an indication of methanogenesis inhibition through the hydrolytic and acetogenic step, whose microorganisms exhibit growth rate much higher than that of the methanogenic ones.
