Structural and composition modification of Harum Manis mango (Mangifera indica) leaves via chemical pretreatment for bioethanol production

Optimizing two stage chemical Pretreatment for Enset ventricosum: A Response Surface Methodology Approach to Enhance Bioethanol Production Efficiency

“…7) revealed various functional groups in both pretreated and untreated Enset ventricosum samples within the wavenumber range of 400 to 4000 cm-1. The shifts in peak positions after the twostage chemical pretreatment suggest changes in the chemical composition of Enset ventricosum, similar to what was observed by Mahadevan and his colleague [31] in Mangifera indica leaves. The FTIR spectra of the pretreated samples displayed characteristic bands at 1346 cm-1 and 3400 cm-1, representing C-H bonds in cellulose and hemicellulose, which suggests that Enset ventricosum leaves, are suitable for bioethanol production.…”

“…According to [31] Enset Ventricosum leaves were placed in a conical ask with a solution containing 1% acid (v/v) or alkali (w/v) at a solid-to-liquid ratio of 1:10. The mixture was stirred for 5 minutes at 200 rpm.…”

“…After 24 h, the hydrolysate was centrifuged at 4°C for 20 min at 4000 rpm. The supernatant (liquid fraction) was withdrawn to analyse the total reducing sugar concentration using the dinitrosalicyclic acid (DNS) method [31].…”

Pretreatment of barley straw with acid and alkaline solutions to boost the efficiency of fermentable yield enzymatic degradation in the separated fermentation technique for ethanol production

“…The combined pretreatment could help solve the problem of how to treat biomass before it is used and give lignocellulosic biorefinery some clear vision (Tarrsini et al, 2021). Several types of lignocellulosic feedstocks, including empty fruit bunch fibers of oil palm, grass, corncob, sugarcane bagasse, and rice straw, have been processed using configurations of the method that involve combined acid and alkaline pretreatment (Guo et al, 2013;Kim et al, 2013;Li et al, 2017;Palamae et al, 2017;Wang et al, 2013).…”

Green synthesized TiO2 nanoparticles: Structural characterization and photoinduced antifungal activity against P. steckii

“…Benzophenones are the most abundant of the polyphenols found in the mango leaf, especially mangiferin. Previous researches have shown that mango leaves and their pure compounds unfold anti‐inflammatory, immunomodulatory, anti‐apoptotic, anti‐tumoral, and lipid profile regulating properties (Tarrsini et al., 2021; Bastante et al., 2021; Kumar et al., 2021). However, minimal studies are available regarding the biosynthesis of TiO 2 nanomaterials using mango leaves.…”
