“…Another use given to rice residues was to obtain mesoporous nanostructured materials. Carraro et al ( 2021 ) prepared a mesoporous material for use as a catalyst in degrading endocrine disruptors by first washing and drying rice husks at 100 °C. The husks were then treated with 1M HNO 3 and filtered, followed by another round of drying for 24 h and calcination at 800 °C.…”

Residual lignocellulosic biomass (RLB) is a valuable resource that can help address environmental issues by serving as an alternative to fossil fuels and as a raw material for producing various value-added molecules. To gain a comprehensive understanding of the use of lignocellulosic waste in South America, a review was conducted over the last 4 years. The review focused on energy generation, biofuel production, obtaining platform molecules (such as ethanol, hydroxymethylfurfural, furfural, and levulinic acid), and other materials of interest. The review found that Brazil, Colombia, and Ecuador had the most RLB sources, with sugarcane, oil palm, and rice crop residues being the most prominent. In South America, RLB is used to produce biogas, syngas, hydrogen, bio-oil, biodiesel, torrefied biomass, pellets, and biomass briquettes. The most studied and produced value-added molecule was ethanol, followed by furfural, hydroxymethylfurfural, and levulinic acid. Other applications of interest that have been developed with RLB include obtaining activated carbon and nanomaterials. Significant progress has been made in South America in utilizing RLB, and some countries have been more proactive in regulating its use. However, there is still much to learn about the potential of RLB in each country. This review provides an updated perspective on the typification and valorization of residual biomass in South America and discusses the level of research and technology being applied in the region. This information can be helpful for future research on RLB in South America.

“…The caryopsis consists of pericarp outer layers, seed coat, embryo (germ), and the endosperm (Juliano, 2016; Upadhyay & Karn, 2018). Rice is an important crop used as staple food in many countries, and following dehusking and milling of the paddy rice, the resultant husk (20% of harvest and rich in silica) and bran (10% of harvest) can be used in industries such as agriculture (as biological control agents, soil fertilizers, mushroom subdtrates and mulching), food and feed, water refining, dye removal, fuel and other energy resources, construction materials (ceramics, concrete, and firebrick) (Abdul Wahab et al., 2020; Edrisi et al., 2018; Urtecho et al., 2019; Hossain et al., 2021; Lat Reano, 2020; Sala et al., 2020; Win et al., 2019), and for remediation purposes (Carraro et al., 2021; Pham, 2020; Shamsollahi & Partovinia, 2019; Yulnafatmawita et al., 2020) in a circular bioeconomy fashion. With many available genetic resources and a completely sequenced genome, rice has been considered as a model system for grass cell wall research (Li et al., 2018).…”

Genetic dissection of monosaccharides contents in rice whole grain using genome‐wide association study

2023

The simplest form of carbohydrates are monosaccharides which are the building blocks for the synthesis of polymers or complex carbohydrates. Monosaccharide contents of 197 rice accessions were quantified by HPAEC‐PAD in rice (Oryza sativa L.) whole grain (RWG). A genome‐wide association study (GWAS) was carried out using 33,812 single nucleotide polymorphisms (SNPs) to identify corresponding genomic regions influencing neutral monosaccharides contents. In total, 49 GWAS signals contained in 17 genomic regions (quantitative trait loci [QTLs]) on seven chromosomes of rice were determined to be associated with monosaccharides contents of whole grain. The QTLs were found for fucose (1), mannose (1), xylose (2), arabinose (2), galactose (4), and rhamnose (7) contents, all of which are novel. Based on co‐location of annotated rice genes in the vicinity of GWAS signals, the constituents of the whole grain were associated with the following candidate genes: arabinose content with α‐N‐arabinofuranosidase, pectinesterase inhibitor, and glucosamine‐fructose‐6‐phosphate aminotransferase 1; xylose content with ZOS1‐10 (a C2H2 zinc finger transcription factor [TF]); mannose content with aldose 1‐epimerase‐like protein and a MYB family TF; galactose content with a GT8 family member (galacturonosyltransferase‐like 3), a GRAS family TF, and a GH16 family member (xyloglucan endotransglucosylase/hydrolase xyloglucan 23); fucose content with gibberellin 20 oxidase and a lysine‐rich arabinogalactan protein 19, and finally rhamnose content with myo‐inositol‐1‐phosphate synthase, UDP‐arabinopyranose mutase, and COBRA‐like protein precursor. The results of this study should improve our understanding of the genetic basis of the factors that might be involved in the biosynthesis, regulation, and turnover of monosaccharides in RWG, aiming to enhance the nutritional value of rice grain and impact the related industries.
