“…Lima et al [16] reported a positive linear correlation between glucose production and cellulose crystallinity index in Eucalyptus, whereas in the same species an opposite correlation was found by Sun et al [17]. However, in spite of the above contrasting reports, in our research we correlate the percentage of crystalline cellulose as a biomass basis and not as an index [18]. In sweet sorghum, enzymatic hydrolysis was more effective for forage sorghums with a low crystalline cellulose index and easily transformed crystalline cellulose to amorphous cellulose, despite initial cellulose content [19].…”

Research was carried out in southern Italy with the aim to assess the quality of faba bean residual biomass and its potential for biorefinery application. Faba bean is a sustainable crop, due to its ability to fix atmospheric nitrogen, and a large amount of biomass remains after harvest which can be valorised for energy production. Greenhouse and early planting are known to affect pod yield and, in this respect, even the residual biomass quality needs to be assessed. For this purpose, the effects of five planting times (i.e. the dates of transplants ranging from 27 September to 22 November at two-week interval, earlier and later than the common planting date of 25 October in Naples province) on pods yield, residual biomass, and saccharification potential were evaluated in faba bean grown in open field and in greenhouse. The third planting time resulted in the highest fruit and residual biomass yield under greenhouse, whereas the fourth was the best in open field. Harvest index was best affected by the third and fourth planting times in open field. Greenhouse grown biomass showed higher values of lignin, hemicellulose and pectin, compared to open field, whereas the opposite trend was recorded with cellulose. Lignin content showed a gradual decrease from the first to the last planting time (17.7%-13.7% biomass fraction respectively), as well as pectin (from 14.1 to 11.5% biomass fraction); conversely, cellulose increased from the first to the last planting time (from 41.1 to 48.7% biomass fraction). Glucose was the most represented monosaccharide (46.7 mol%), followed by xylose (27.4 mol%) and galactose (9.9 mol%). Overall, the potential of faba bean residual biomass for energy production was best affected by open field growing, the latest planting time and alkali pre-treatment, the latter giving the highest value of saccharification (60.7 g kg −1 h −1 compared to 27.6 relevant to hot water pre-treatment).

“…Jatropha curcas shells were used to study the effect of dilute sulphuric acid pre-treatment on hydrolysis. Almost 70% of enzymatic conversion of cellulose was obtained after following this pre-treatment protocol (Martín et al, 2015).…”

“…O teor de cinzas (16,4%) é maior do que em fontes biológicas lignocelulósicas típicas, e é comparável apenas a alguns materiais, tais como casca de arroz e casca de cevada. A xilose foi o principal açúcar hemicelulósico, seguido pela manose, galactose e arabinose (Martín et al, 2015). O material lignocelulósico é constituído de três tipos de polímeros: celulose, hemicelulose e lignina, que se encontram em associação por pontes de hidrogênio ou ligação covalentes.…”

O pinhão manso (Jatropha curcas L.) tem-se apresentado como uma oleaginosa importante, com aplicações medicinais e industriais. Assim o trabalho aqui apresentado teve como principal objetivo avaliar o potencial do uso de pinhão manso para a geração de biocombustíveis. A Jatropha tem relevância especialmente para o desenvolvimento da bioenergia, pela percentagem de óleo em suas sementes que pode variar de 40-60%, servindo para a fabricação de biodiesel. As cascas de seus frutos podem ser consideradas para a produção de etanol por seu alto conteúdo de celulose. A torta, que fica depois da extração de óleo, é um resíduo sólido rico em nutrientes e proteínas mas limitada, pois possui vários fatores anti-nutricionais e tóxicos como os ésteres de forbol, mas com enorme potencial para a geração de biogás. Embora existam tecnologias para o desenvolvimento dos usos industriais desta espécie, não existe suficiente quantidade de produção dos frutos por planta e gente que se motive a plantar e colher, para suprir a demanda necessária e ser uma cultura altamente lucrativa.
