Abstract
To treat soluble and solid wastes and recover energy from them, high rate methane fermentation, especially using the UASB (upflow anaerobic sludge blanket) reactor, and hydrogen fermentation using various microorganisms and microbial consortia have been investigated intensively in Japan. In this chapter, recent works on high rate methane fermentation in Japan are reviewed, focusing on: 1) basic studies into the applicability of the UASB reactor for various substrates such as propionate, lactate, ethanol, glucose and phenol; 2) its applications to unfeasible conditions, such as lipid and protein containing wastes, low temperature and high salt-containing wastes; 3) progress made in the field of advanced UASB reactors, and; 4) research into methane fermentation from solid wastes, such as from cellulosic materials, municipal sewage sludge, and mud sediments. Following this, although hydrogen fermentation with photosynthetic microorganisms or anaerobic bacteria was researched, for this review we have focused on fermentative hydrogen production using strictly or facultative anaerobes and microbial consortia in Japan, since high rate production of hydrogen-methane via a two-stage process was judged to be more attractive for biological hydrogen production and wastewater treatments.
