“…However, the average value of the lignin found in this study (2.6%) was lower than the values recorded for some lingocellulosic biomasses that exhibit a potential for the production of second generation ethanol, such as wheat straw, with 13 to 15% lignin, and bagasse from sugarcane, containing 23 to 32% lignin (Saini et al, 2015). Lignin is a key limiting factor in the saccharification of lignocellulosic feedstocks (Van der Weijde et al, 2016).…”

The increased supply of ethanol fuel and its spread as an alternative to fossil fuels depend on the exploration of biomasses that can be regarded as alternatives to sugarcane and maize. In this study, the agricultural productivity and the potential for production of ethanol from roots and the aerial portion of twenty sweet potato genotypes were evaluated. The roots and branches were harvested 180 days after planting. Starch, hemicellulose, cellulose, lignin and soluble sugars from sweet potato roots or branches were determined and expressed as percentage of dry matter produced per hectare. The genotype UFVJM 28 stood out for the production of root and branches (fresh material), yielding 43.5 and 31.7 t ha . Considering the combined use of roots and branches, at least four sweet potatoes genotypes presented a potential for ethanol production greater than 4000 L ha -1 in a 180-day cycle.

“…It was previously shown that OPM-9 ( M . × giganteus ), the most widely exploited miscanthus variety, has a considerably lower quality for biofuel production compared to many other accessions (van der Weijde et al, 2016a), which is shown here to be the case across diverse environments.…”

“…Saccharification efficiency of the samples was assessed by the conversion of cellulose into glucose and hemicelluloses into xylose using a mild alkaline pretreatment and enzymatic saccharification reaction, essentially as described by van der Weijde et al (2016a). Reactions were carried out in triplicate using 500 mg subsamples per stem sample.…”

To investigate the potential effects of differences between growth locations on the cell wall composition and saccharification efficiency of the bioenergy crop miscanthus, a diverse set of 15 accessions were evaluated in six locations across Europe for the first 3 years following establishment. High-throughput quantification of cellulose, hemicellulose and lignin contents, as well as cellulose and hemicellulose conversion rates was achieved by combining near-infrared reflectance spectroscopy (NIRS) and biochemical analysis. Prediction models were developed and found to predict biomass quality characteristics with high accuracy. Location significantly affected biomass quality characteristics in all three cultivation years, but location-based differences decreased toward the third year as the plants reached maturity and the effect of location-dependent differences in the rate of establishment reduced. In all locations extensive variation in accession performance was observed for quality traits. The performance of the different accessions in the second and third cultivation year was strongly correlated, while accession performance in the first cultivation year did not correlate well with performance in later years. Significant genotype-by-environment (G × E) interactions were observed for most traits, revealing differences between accessions in environmental sensitivity. Stability analysis of accession performance for calculated ethanol yields suggested that selection for good and stable performance is a viable approach. Environmental influence on biomass quality is substantial and should be taken into account in order to match genotype, location and end-use of miscanthus as a lignocellulose feedstock.

“…Differences in accuracy of reference wet chemical procedures used to obtain ADL and LIG, and in the magnitude of their concentrations, have been observed by others [29,[60][61][62]. While both are Klason lignin procedures, LIG determination involves an additional acid hydrolysis step in an autoclave and the ADL procedure may not retain all lignin components [63]. There were no differences between switchgrass cultivars for biomass compositional traits (Table 5), but miscanthus lines differed in concentrations of both forms of ash and lignin.…”

Switchgrass and Giant Miscanthus Biomass and Theoretical Ethanol Production from Reclaimed Mine Lands

Switchgrass (Panicum virgatum L.) and giant miscanthus (Miscanthus x giganteus Greef & Deuter ex Hodkinson & Renvoize) are productive on marginal lands in the eastern USA, but their productivity and composition have not been compared on mine lands. Our objectives were to compare biomass production, composition, and theoretical ethanol yield (TEY) and production (TEP) of these grasses on a reclaimed mined site. Following 25 years of herbaceous cover, vegetation was killed and plots of switchgrass cultivars Kanlow and BoMaster and miscanthus lines Illinois and MBX-002 were planted in five replications. Annual switchgrass and miscanthus yields averaged 5.8 and 8.9 Mg dry matter ha, respectively, during 2011 to 2015. Cell wall carbohydrate composition was analyzed via near-infrared reflectance spectroscopy with models based on switchgrass or mixed herbaceous samples including switchgrass and miscanthus. Concentrations were higher for glucan and lower for xylan in miscanthus than in switchgrass but TEY did not differ (453 and 450 L Mg , respectively). In response to biomass production, total ethanol production was greater for miscanthus than for switchgrass (5594 vs 3699 L ha ). Relative to the mixed feedstocks model, the switchgrass model slightly underpredicted glucan and slightly overpredicted xylan concentrations. Estimated TEY was slightly lower from the switchgrass model but both models distinguished genotype, year, and interaction effects similarly. Biomass productivity and TEP were similar to those from agricultural sites with marginal soils.Keywords Cellulosic bioenergy feedstock . Mine reclamation . Near-infrared reflectance spectroscopy .
