“…Therefore, the first steps before fermentation of feedstock with the higher content of cellulose and LCC should be material pretreatment in order to break bonds in cellulose and in LCC (Li et al 2015). According to Li et al (2011) after releasing cellulose from LCC sheath, the first step of the fermentation process is depolymerisation throughout cellulolytic bacteria, which produce cellulase. Subsequently, the cellulose disintegration products (such as cellobiose and soluble cellulodextrin of higher order) can be transformed into methane and carbon dioxide after a series of transformations (Bhadra et al 1986;Lynd et al 2002;Zhang and Lynd 2005;Jeihanipour et al 2010Jeihanipour et al , 2011.…”

The purpose of the paper is designation of the changes in the structure of cellulose after the methane fermentation process of Miscanthus and Sorghum harvested during the growing season and afterwards. The percentage and structure of cellulose before and after fermentation were studied. Investigations into changes of the cellulose structure were conducted by the SEC, FT-IR and XRD methods. The average percentage of cellulose after the growing season for Miscanthus varieties was higher and for Sorghum varieties was lower. As a result of the fermentation, the percentage of cellulose for both investigated species harvested in two growth seasons was lower. The degree of polymerisation for the plants harvested after the growing season was lower for the most feedstock. As a result of the fermentation process, the degree of polymerization increased for each of the investigated feedstock. However, crystallinity of cellulose remained at the same level for Miscanthus and decreased for Sorghum. It was shown that changes were different in the cellulose structure of the compared species.

“…Anaerobic digestion (AD) is a promising and viable technology for treating various types of organic wastes and simultaneously producing biogas as a renewable energy carrier [3]. At the same time, corn stalk is an important lignocellulosic biomass that shows promise as a potential substrate for AD [4].…”

“…Although several continuous process reactors including Valorga, Kompogas, and Dranco for solid materials have dominated the market place for solid-state AD systems treating municipal solids waste (MSW), they have not been established for the processing of lignocellulosic biomass or energy crops because of complex process, high maintenance requirements, high parasitic energy loss, etc. [3]. The continuous stirred tank reactor (CSTR) does not function well with lignocellulosic materials such as corn stalk as well.…”

“…Effect of Pretreatment on biogas production was observed in this study with the addition of enzyme as much as 5% volume of the solution for all the variables, the addition of NaOH as much as 3% of the volume of the solution. Biogas volume measurement results during the 60-day trial is shown as a SS-AD biogas yield is calculated from the daily biogas volume divided by the content of TS on rice husk [18]. The cumulative biogas yield per unit TS and presented in Figure 2 to 6.…”

Abstract. Rice husk is one of agricultural waste generated from the mill is potential to be converted to biogas. Otherwise, biogas production facing problem due to the high lignin content. This research is objected to study the effect of enzymatic pretreatment and C/N ratio to biogas production from rice husk by solid state anaerobic digestion (SS-AD). The laboratory scale-anaerobic digestions was used in this work. It is operated in batch system and with room temperature. Total solid (TS) was set 21%. Enzymatic pretreatment was conducted using lignase enzyme. Carbon to Nitrogen (C/N) ratio was varied from 20, 25, 30, and 35. The C/N ratio is varied by adding some quantity of technical urea to the substrate. Biogas formed was measured using water displacement method in every two days. The result showed that enzymatic pretreatment could increase biogas production from 30 to 55 %. The highest biogas production was obtained at C/N ratio 35. Specific biogas production on C/N ratio of 20, 25, 30, and 35 were respectively 12.0, 12.6, 13.5 and 18.2 ml/gr TS. The volumetric loading resulted by SS-AD was higher than liquid anaerobic digestion (L-AD). The further research need to conduct for optimization the enzyme concentration and C/N ratio.
