“…29 Kangrang et al 104 investigated the effect of microbial consortia obtained from cattle and horse manure, and decomposed wood for production of cellulase, and further enhancement of biogas production from rice straw. To select the most efficient consortium, cellulase enzymes were extracted and 105 cultivated mesophilic lignocellulolytic microbial consortium BYND-5 and applied it to enhance the biogas production from rice straw. The results showed degradation efficiency of BYND-5 for rice straw of more than 49 % after 7 days of cultivation at 30 °C.…”

Biomass availability is one of the key factors for biogas production in the future. The current status and possibilities for utilizing harvest residues (soybean straw, corn stover and sunflower stalk) in Croatia for biogas production is given. In the last few decades, different pretreatment methods have been developed for the degradation of different lignocellulosic biomass, but many of them are environmentally unfriendly and sometimes very expensive. More research and development is necessary in order to find both economically and environmentally friendly pretreatment methods. This paper provides a review on the mechanical, physical, and biological methods used for different lignocellulose material pretreatment. Harvest residues are usually left in the field, but with the improvement of the pretreatment process along with soil protection, they could be used for the production of huge amounts of energy in the future.

“…Numerous studies have examined anaerobic cellulosedegrading bacteria and their enzymatic capabilities in order to clarify the degradation mechanisms and identify ways to enhance degradation rates. However, most of these studies have been performed on samples from gut and soil ecosystems [3,13,15,16] and only a few have examined cellulose-degrading bacteria in biogas digesters [17][18][19].…”

Biogas production from wheat straw: community structure of cellulose-degrading bacteria

Background: Wheat straw is one of the most abundant crop residues produced in the world, making it highly interesting as a substrate for biogas production. However, due to the complex structure, its degradability and gas yield are low. The degradability can be improved by pre-treatment, making the material more accessible to microbial degradation. Methods: To investigate the microbial response to straw as a feed stock for biogas production, this study examined the community structure of cellulose-degrading bacteria in lab-scale biogas digesters operating with manure, alone or in co-digestion with straw, with and without pre-treatment (steam-explosion) at different temperatures. The community was studied by targeting the functional gene encoding glycoside hydrolases of families 5 and 48 using T-RFLP, clone libraries and qPCR. Results: In general, bacteria belonging to the phyla Firmicutes and Bacteroidetes dominated the cellulose-degrading bacteria community in all digesters. The degree of similarity to the characterised bacteria was often low, and some clones were more closely related to the uncultured bacteria. The addition of straw, pre-treatment of straw and increasing operating temperature all affected the cellulose-degrading community structure, with differing responses in the cel48 and cel5 communities. Both communities changed in response to temperature, while only the cel5 community was affected by the addition of straw and cel48 community by straw pre-treatment. Conclusions: The addition of straw, pre-treatment of straw and operating temperature all affected the cellulosedegrading community in biogas digesters, but there were no major differences in the digester performance and gas yield.

“…In addition, the highest percentage of methane content was 50-55% and it was higher than in the control, but lower than that obtained for maize silage samples treated by MCHCA (∼64%). Yan et al (2012) developed a mesophilic consortium BYND-5, which was used for the pretreatment of rice straw, and which enhanced the total biogas yield by up to 9.3% and the percentage content of methane by up to 10%. Generally, FIGURE 6 | Decrease of sCOD and VFAs concentration during biogas production (anaerobic digestion) from maize silage.…”
