“…The products of this first step are simple sugars, amino acids, and fatty acids. This step has been reported as being the rate limiting step for hard-to-digest biomass (Fernandes et al, 2009) such as lignocellulose and keratin-rich wastes. Moreover, some toxic by-products can be formed during this step (Neves et al, 2006).…”

“…In other words, in a contex of a continuous culture, kinetic stress is defined as the imposition of a constantly reducing value of the solids retention time until it is lower than the limiting value; hence it will result in a washout of the microorganism [28]. Most researchers report that the rate-limiting for complex organic substrate is the hydrolysis step [29]- [35] due to the formation of toxic byproducts (complex heterocyclic compounds) or non-desirable volatile fatty acids (VFA) formed during hydrolysis step [36] [37]: whereas methanogenesis is the rate limiting step for easy biodegradable substrates [36] [38]- [40]. The anaerobic digestion process can be divided into two phase as illustrated in Figure 1.…”

The search for alternative energy and fuels has motivated researchers to focus on renewable and sustainable means of getting them instead of relying on the conventional way of energy and fuel production. Anaerobic digestion is a biochemical process during which complex organic matter is decomposed in absence of oxygen, by various types of anaerobic microorganisms. The process of Anaerobic digestion is appropriate for all waste water treatment systems given that the solid can be introduced to the system at an acceptable concentration. Biogas, the product of anaerobic digestion process is a clean and renewable form of energy which can be a substitute for conventional sources of energy which are causing ecological-environmental problems and at the same time depleting at a faster rate. This paper reviews the anaerobic digestion process and its complexities; it covers different stages involved in the process, the substrate used in the process, the relationship between the substrate and microorganisms and important operating parameters such as pH, temperature and loading rate.

“…), biological (fungi, enzymatic hydrolysis, etc.) or combination of them (Adel et al, 2010;Fernandes et al, 2009;Mosier et al, 2005;Sun and Cheng, 2002). The efficiency of a pretreatment can be evaluated by the induced matter solubilisation, the increase of anaerobic biodegradability and its cost.…”

This study investigated the effects of microwave pretreatment of switchgrass in order to enhance its anaerobic digestibility. Response surface analysis was applied to screen the effects of temperature and time of microwave pretreatment on matter solubilisation. The composite design showed that only temperature had a significant effect on solubilisation level. Then the effects of the microwave pretreatment were correlated to the pretreatment temperature. The sCOD/tCOD ratio was equal to 9.4% at 90°C and increased until 13.8% at 180°C. The BMP assays of 42 days showed that microwave pretreatment induced no change on the ultimate volume of methane but had an interesting effect on the reaction kinetic. Indeed, the time required to reach 80% of ultimate volume CH 4 is reduced by 4.5 days at 150°C using the microwave pretreatment.
