“…Most studies recommend an operating C/N ratio range of 20/1 to 30/1 with an optimal ratio of 25/1 for anaerobic bacterial growth in an AD system (Estevez et al, 2012). Improper C/N ratios can result in high total ammonia nitrogen (TAN) release and/or high volatile fatty acids (VFA) accumulation in the digester.…”

“…After determining the methane concentration in the headspace, the methane yield was calculated using the method reported by Estevez et al (2012), based on the European Chemical Industry Ecology and Toxicology Center (ECETOC) procedure (Stringer 1998). The differences in methane production between the substrate vials and the blank vials were considered the methane yields of the investigated samples.…”

“…Therefore, the lignocellulosic biomass must be pretreated to improve the efficiency of hydrolysis (Zhu et al 2010). Currently, several different pretreatment methods (including biochemical, enzymatic, mechanical, and thermal treatments) are being applied to agricultural residues (Estevez et al 2012;Horn et al 2011;Jackowiak et al 2011).…”

Two pretreatment methods, microwave irradiation and steam explosion, were investigated in this work. The aim of the study was to investigate whether these methods would improve the biodegradability of wheat straw as a lignocellulosic feedstock. Microwave pretreatment was carried out on milled straw with an irradiation time of 15 minutes, at a temperature of either 200 or 300 °C in the oven. The steam explosion pretreatment was carried out on milled straw at 210 °C for 10 minutes. To determine the methane production potential, anaerobic digestion batch trials were run under mesophilic conditions for 60 days. The methane yields of the microwave-pretreated straw decreased by 65% for an attained temperature of 200 °C and by 92% for 300 °C. After steam explosion pretreatment, however, the methane yields of the straw increased by approximately 20% when compared to untreated straw samples. These results indicate that microwaving does not optimize methane production from wheat straw, while steam explosion yields positive results.
