“…The soluble sugar level varied from 1.4% to 32.1% with a relatively high CV of 36.6%, which approximated that in sweet sorghum stems reported in a previous study . Meanwhile, we measured a diverse ash level ranged from 1.8% to 5.2% with a CV of 20.6%, much lower than that in corn stover (Wang et al, 2014). By contrast, JA exhibited relatively lower diversity in cell wall polymers with a CV of 8.5% for cellulose, 11.6% for hemicellulose, 9.9% for lignin and 12.5% for pectin.…”

These results indicate that JA stem could be a quality feedstock for bioethanol production due to its higher carbohydrates and lower ash levels compared with corn stover (Wang et al, 2014).…”

Jerusalem artichoke (JA) has been known as a potential nonfood feedstock for biofuels. Based on systems analysis of total 59 accessions, both soluble sugar and ash could positively affect biomass digestibility after dilute sodium hydroxide pretreatment (A). In this study, one representative accession (HEN-3) was used to illustrate its enzymatic digestibility with pretreatments of ultrasonic-assisted dilute sodium hydroxide (B), alkaline peroxide (C), and ultrasonic-assisted alkaline peroxide (D). Pretreatment D exhibited the highest hexose release rate (79.4%) and total sugar yield (10.4 g/L), which were 2.4 and 2.6 times higher, respectively, than those of the control. The analysis of cellulose crystalline index (CrI), cellulose degree of polymerization (DP), thermal behavior and SEM suggested that alkali-based pretreatments could distinctively extract lignin and pectin polymers, leading to significant alterations of cellulose CrI and DP for high biomass saccharification. Additionally, hydrogen peroxide (H2O2) could significant reduce the generation of fermentation inhibitors during alkali-based pretreatments.

“…On the other hand, the oxygen content in cobs of the studied maize (45.0%) was higher than in Turkish (43.8–44.7%), Serbian (43.9%), Hawaiian (43.9%) and Chinese (43.5%) maize cobs and lower than in Malaysian cob samples (48.2%) of maize [ 13 , 34 , 35 , 36 , 37 ]. Maize stover fractions differed in their elemental composition, which in turn is related to climatic conditions, the variety of maize, harvest time and soil type [ 38 , 39 , 40 , 41 ]. Therefore, it seems important to study the relationship between the composition and chemical structure of individual maize fractions, as it is important when designing technological processes for maize waste processing, including balance calculations related to the biogas fermentation process.…”

Chemical and Structural Characterization of Maize Stover Fractions in Aspect of Its Possible Applications

In the last decade, an increasingly common method of maize stover management is to use it for energy generation, including anaerobic digestion for biogas production. Therefore, the aim of this study was to provide a chemical and structural characterization of maize stover fractions and, based on these parameters, to evaluate the potential application of these fractions, including forbiogas production. In the study, maize stover fractions, including cobs, husks, leaves and stalks, were used. The biomass samples were characterized by infrared spectroscopy (FTIR), X-ray diffraction and analysis of elemental composition. Among all maize stover fractions, stalks showed the highest C:N ratio, degree of crystallinity and cellulose and lignin contents. The high crystallinity index of stalks (38%) is associated with their high cellulose content (44.87%). FTIR analysis showed that the spectrum of maize stalks is characterized by the highest intensity of bands at 1512 cm−1 and 1384 cm−1, which are the characteristic bands of lignin and cellulose. Obtained results indicate that the maize stover fraction has an influence on the chemical and structural parameters. Moreover, presented results indicate that stalks are characterized by the most favorable chemical parameters for biogas production.

“…Such a high production of maize grain causes crop residues, such as leaves, stalks, husks, and cobs, which can constitute up to 50% of the dry matter yield of whole maize plants [8,9]. The fractions mentioned above have different chemical compositions, structure, and fiber properties [10,11], harvesting times, and even topography or soil types [12,13]. For example, sufficient storage as a result of ensiling operations enables 1.1%–2.2% reduced loss of organic matter compared to in open-air storage (63.1%) [7].…”

Maize Straw as a Valuable Energetic Material for Biogas Plant Feeding

et al. 2019

Maize has great potential, especially as a substrate for biofuels production. The aim of this paper is to analyze the possibility of usage in methane fermentation maize straw harvested in different weather conditions, which had an influence on different physical parameters, mainly the dry mass content. The research has shown that maize straw harvested in Central-Eastern Europe can have a broad spectrum of dry mass content, which is related to diverse weather conditions during autumn. However, independently from moisture content, maize straw can be a good (for more wet material) or very good (for more dried straw) substrate for the biogas plant. With the methane productivity reaching 201–207 m3/Mg of fresh mass, this material is a significantly better substrate than that typically used in Europe maize silage (approximately 105 m3/Mg FM). It was noted that the retention time for maize straw (36–42 days) is longer than in the case of maize silage (less than 30 days). However, this difference is quite small and can be accepted by the biogas plant operators.
