Suberin and hemicellulose in sugarcane cell wall architecture and crop digestibility: A biotechnological perspective

Abstract: Sugarcane is a highly efficient biomass producer used in the last decades for bioethanol and bioelectricity production, as well as for animal feeding. Together with lignin, suberin is a major factor for the low sugarcane biomass digestibility by ruminants. The lipid–phenolic biomolecular composition and the ultrastructure of suberin and associated waxes confer them extraordinary properties of hydrophobicity, flexibility, and anti‐microbial resistance, responsible for the low digestibility of suberized tissues.… Show more

“…Concerning the aromatic fraction of suberin, hydroxycinnamates esters, such as PCA, fortify the crosslinking between arabinoxilans and suberin fatty acids; besides PCA deposition has been associated with highly suberized tissues. Even though there is some of the esteri ed PCA esteri ed to polysaccharides, as previously mentioned, most of the PCA in grasses is ester bond to S units of lignin [60,61].…”

“…La fibra es un componente seco e insoluble en el agua del tallo que resulta importante en la medición de la calidad de la caña debido a su relación inversa con la extracción de jugo y la eficiencia de la molienda (Islam et al, 2021), por lo tanto, los niveles aceptables se encuentran entre 10 y 14% (Gravois y Milligan, 1992), ya que, de lo contrario por cada aumento de 1% en el contenido de fibra se provoca una disminución en los valores teóricos de sacarosa recuperable que varía del 1.51 al 3.02 g kg -1 de caña (Glaz et al, 2010). En este componente las variedades no mostraron diferencias entre sí, atribuido a la estabilidad química que presenta este cultivo en los compontes de la pared celular, formada principalmente por hemicelulosa, celulosa y lignina, que en conjunto proporcionan soporte a los tallos (Waclawovsky et al, 2010;Figueiredo et al, 2019).…”

“…For example, black locust bark suberin with known biocidal activity [ 145 ] must be considered in microbial fermentation and enzymatic conversion of sugars and pretreatment strategies of biomass containing suberin [ 146 ]. It is also relevant to note that suberin has been shown to have significant impacts on the digestibility of sugarcane cultivated for animal forage [ 147 , 148 ]. Enzymatic conversion of elephant grass bark was not as readily degraded relative to the pith possibly due to the presence of biopolymers such as cutin as studied by Perez-Boada [ 149 ].…”
