Disclosed herein is a process for enhancing anaerobic biohydrogen production, including: adding into a reactor an organic waste containing hydrogen-producing anaerobic bacteria, a first substrate, and a carrier that permits the hydrogen-producing anaerobic bacteria to adhere and grow thereon, so as to form a mixture; acclimating the mixture at a first agitation speed ranging from 5 to 60 rpm, so that the hydrogen-producing anaerobic bacteria adhere to and proliferate on the carrier, followed by the formation of granular biomasses within the acclimated mixture; and feeding a second substrate into the reactor at a second agitation speed ranging from 5 to 60 rpm, so that the content of the granular biomasses is increased while the second substrate is anaerobically fermented by the hydrogen-producing anaerobic bacteria in the granular biomasses to result in the production of hydrogen.
