“…Higher biogas yield of pretreated corn stover was not achieved. Some other lignocellulosic biomass like wheat straw [98][99][100] , Japanese cedar wood 101 , and rice straw 102,103 , have also been successfully degraded using whiterot fungi, which ultimately affected the increase in the production of biogas.…”

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.

“…Moreover, fungi with high lignin-degrad- ing selectivity and/or degradation ability are preferred. Fungi with high lignin-degrading selectivity have been proved to enhance methane production from lignocellulosic biomass [5,7,9]. Fungi with high degradation ability decay lignocellulosic biomass rapidly and throughly to enhance yeast production for improvement of protein content and palatability of feed [2].…”

“…has shown high lignin-degrading selectivity in different types of lignocellulosic biomass decayed and has been used to enhance methane production [9,24]. �üller and Trösch [9] concluded that Pleurotus florida showed the fastest delignification among twenty-two tested fungi. Wheat straw pretreated by this fungus was fermented anaerobically to biogas, and the gas yield was twice the amount of the untreated straw.…”

To screen applicable fungi for their ability to decay cassava residue, nineteen lignin-degrading fungi were isolated by guaiacol and azure B plates. Cassava residue decayed characteristics of the isolates were evaluated systematically by principal component analysis (PCA) of weight and components loss data, and compared with those of Phanerochaete chrysosporium and Trametes sp. SYBC-L4. Four groups of decayed cassava residue were identified. Fungus N1 and N3 grouped together and showed high lignin-degrading selectivity. Fungus N5 and N8 grouped with P. chrysosporium and showed high degradation ability. During the four weeks incubation, the lignin-degrading selectivity value of fungus N3 ranged from 1.14 to 1.38 and was the best, the weight loss of fungus N5 and N8 achieved 30.93% and 33.34%, respectively. Fungus N3, N5, and N8 were identified as Pleurotus sp., Trametes sp. and Coriolopsis sp. based on 18S rDNA gene sequences, respectively. PCA is an effective method in recognizing cassava residue decayed characteristics of fungi and is helpful to screen fungi for their potential application. The three screened out fungi could be used to decay cassava residue for enhancement of its bioconversion efficiency.Keywords: Lignin-degrading fungi, cassava residue, decay, principal component analysis, screening.Исследованы девятнадцать грибов, разрушающих лигнин с целью разрушения отходов маниоки.

“…The subtrates with high content of cellulose and lignin that interlink each other [10], becomes difficult to hydrolyze, so that the yield of biogas is low. To overcome this, some researchers have proposed some pretreatment processes before processing in AD, such as thermo-chemical [12], thermal [2,1], mechanical-chemical-enzymatic [3], alkaline [7], and biological [9] pretreatments. The methods are successful for enhancing the yield of biogas, but the pretreatment processes are less practical, as they require additional equipment and also sometimes use additional chemicals that may add an operational cost.…”

Enhancing biogas quality of indigofera plant waste through co-digestion with cow dung

2018

View full text Add to dashboard Cite

Abstract. The production process of indigofera plants yields 10% of blue natural dyes and wastes are 90%.The biomass wastes from the extraction of indigofera plants are classified as difficult to process in an Anaerobic Digester (AD) because of the large content of hemicellulose in the Indigofera stems. Therefore, the study reports the anaerobic digestion of Indigofera plant wastes co-digested with cow dung for enhancing the biogas quality. The digestion process was conducted in a vessel of 160 L with various weight ratios between Indigofera biomass and cow dung by 0%, 25%, 50%, 75%, and 100%. The results show that the AD reactor temperature kept above 29.5°C with a pH between 6-7 were the key factors for enhancing the biogas quality. The co-digestion between 50% indigofera wastes with 50% cow dung yielded biogas with a CH4 content of about 42% and H2S concentration below 40 ppm showing that the biogas has the potential to be further improved in quality and can be used to fuel the stove and power generation.
