“…The 1st internode of E. arundinaceus had a high lignin content, higher than those of small gramineous plants [e.g., 6.4-19.0% in rice straws (Deng et al 2007;Hattori et al 2012;Jin and Chen 2006;Sangnark and Noomhorm 2004;Suzuki et al 2009), 5.3-17.9% in wheat straws (Hongzhang and Liying 2007;Papatheofanous et al 1998;Saha et al 2005;Xu et al 2006), and 15-21% in corn Kim and Ralph (2010).

Lignin is a major component of the secondary cell walls of vascular plants, and an obstacle in the conversion of plant cell wall polysaccharides into biofuels. Erianthus spp. are large gramineous plants of interest as potential energy sources. However, lignocelluloses of Erianthus spp. have not been chemically characterized. In this study, we analysed lignins, related compounds, enzymatic saccharification efficiencies, and minerals in the ash of the inner and outer parts of the internode, leaf blade and leaf sheath of Erianthus arundinaceus. Lignins in four organs consisted of guaiacyl, syringyl, and p-hydroxyphenyl units. The ratios of syringyl to guaiacyl lignins and lignin contents ranged from 0.43 to 0.79 and 20 to 28%, respectively, with values highest in the outer part of the internode. The amounts of ferulic acid were similar (7.3-11.8 mg g −1 dry weight of cell-wall material) in all four organs, while there was more p-coumaric acid in the inner part of the internode (44.7 mg g −1 dry weight of cell-wall material) than in other organs (25.7-28.8 mg g −1 dry weight of cell-wall material). The enzymatic saccharification efficiency (24 h reaction time) of the leaf blade was 21.6%, while those of the other organs ranged from 10.0 to 15.2%. The leaf blade had the highest ash content (17.1%); the main inorganic element was silicon. This paper provides the first fundamental knowledge of E. arundinaceus lignins.

“…Lignin contents determined by the two methods gave almost identical values. e 1st internode of E. ravennae had a high lignin content, higher than those of small gramineous plants [e.g., 6.4-19.0% in rice straws (Sangnark and Noomhorm 2004;Jin and Chen 2006;Deng et al 2007;Suzuki et al 2009;Hattori et al in press), 5.3-17.9% in wheat straws (Papatheofanous et al 1998;Xu et al 2006;Saha et al 2005;Hongzhang and Liying 2007), and 15-21% in corn stover (Buranov and Mazza 2008)]. e lignin content was similar to that in other large gramineous plants [e.g., 17.4-28.5% in Miscanthus (Higuchi et al 1967a;Ververis et al 2004), and 19.5-36.0% in switchgrass (Hurter 1997;Madakadze et al 1999;Law et al 2001)].…”

ResumoEste trabalho teve como objetivo elucidar, por meio da pirólise analítica acoplada à cromatografia gasosa e espectrometria de massa, alterações na composição química da lignina nas bainhas de plantas de arroz das cultivares BR-Irga 409 e Labelle supridas ou não com silício (Si) e infectadas por Rhizoctonia solani. A concentração de Si nas bainhas das plantas supridas com esse elemento foi significativamente maior (2,7 dag kg -1 ) em comparação com as plantas não supridas (0,45 dag kg -1 ). Na presença de Si, a área abaixo da curva do progresso da queima das bainhas foi significativamente reduzida em 19 e 25%, respectivamente, para as plantas das cultivares BR-Irga-409 e Labelle em relação à ausência desse elemento na solução nutritiva. Com base nos espectros de massas obtidos, foram identificados 33 compostos, dos quais 10 foram produtos da degradação de carboidratos e 23 derivados da lignina. Dentre os derivados da lignina, oito compostos eram do tipo p-hidroxifenila, 11 compostos do tipo guaiacila e quatro compostos do tipo siringila. Nas bainhas das plantas das duas cultivares de arroz, supridas ou não com Si, a concentração de lignina (p-hidroxifenila, siringila (S) e guaiacila (G)) foi de, aproximadamente, 15%. Houve aumento na relação S/G apenas nas bainhas das plantas da cultivar BR-Irga 409 supridas com Si e infectadas por R. solani. A maior concentração de Si nas bainhas das plantas de arroz das duas cultivares, que por sua vez resultou em aumento na relação S/G, contribuiu para reduzir os sintomas da queima das bainhas.Palavras-chave: queima das bainhas, lignina, metabólitos secundários, resistência. Silicon altering compounds derived from the pyrolyses of leaf sheaths of rice plants infected with Rhizoctonia solani AbstractThis study elucidated, through analytical pyrolysis coupled to gas chromatography and mass spectrometry, changes in the chemical composition of lignin on leaf sheaths of rice plants of cultivars BR-Irga 409 and Labelle supplied or non-supplied with silicon (Si) and infected with Rhizoctonia solani. The Si concentration on leaf sheaths of plants supplied with this element was significatively higher (2.7 dag kg ). In the presence of Si, the area under leaf sheath blight progress curve was significantly reduced by 19 and 25% for plants from cultivars BR-Irga 409 and Labelle, respectively, in comparison to the absence of Si. Based on the mass spectra obtained, 33 compounds were identified, 10 of which were products from the degradation of carbohydrates and 23 derivate from lignin. From lignin derivatives, eight compounds were p-hydroxiphenil type, eleven compounds were guaiacyl type and four compounds were syringyl type. On leaf sheaths of both cultivars, the concentration of lignin (p-hydroxiphenil, syringyl (S) and guaiacyl (G)) was around 15%, regardless of Si. There was no increase in the S/G ratio only for the leaf sheaths of BR-Irga 409 supplied with Si and infected with R. solani. High Si concentration on leaf sheaths of both cultivars, which in turn resulted in an increase...
