“…The XRD patterns of WRMA and treated WRMA (Figure 1) showed two peaks characteristic of LCNF: peaks at 15.8 degrees and 22.2 degrees, characteristic of cellulose I. These were similar with the data for dried Musa basjoo [30]. Marais et al [24] also observed XRD peaks at 16 and 22 degrees in extracts from Musa acuminata and Musa balbisianal.…”

“…Pseudo-stems of Musa basjoo were collected from Uchiko town, Ehime Prefecture, Japan. In a previous study [30], the collected Musa basjoo pseudo-stems were dried in the sun for one month and used as samples. The abundance of banana stems presents an increasingly challenging opportunity for further research in the field of banana stem fiber in Indonesia.…”

“…Hydrogen bonds between nanofibers are usually reversible, and in pulps, they are dispersed when dried and immersed in water. In contrast, since Musa basjoo pseudostems are composed of sheet-like CNFs [30], the strong hydrogen bonds, when dried, would have required higher temperature and longer time for re-dispersion. The Musa basjoo pseudo-stem possesses commendable characteristics and holds great potential as a low-energy source for lignocellulose nanofibers.…”

“…Various extraction methods of extracting CNF and LCNF, including alkaline, acid-based [24,26], enzymatic [27], and combinations of chemical/biological with mechanical ones [28,29] are commonly employed for the production of cellulose nanofibers. This research focuses on a modified approach to extract cellulose using NaOH at lower temperatures and shorter extraction times, building upon previous successful extraction of LCNF in one step from Musa basjoo [30]. Alkaline methods, which involve combining NaOH with other compounds, have been extensively utilized by researchers.…”

“…Recently, we succeeded in extracting LCNF from dried pseudo-stems of Musa basjoo, a banana relative, by using a one-step alkalization method using NaOH that combined with a mechanical process at 90 o C within 24 hours [30]. It is usually hard to extract CNF and LCNF from plants by NaOH treatment alone.…”

This study presents a novel approach for the extraction of cellulose nanofibers (CNF) and lignocellulose nanofibers (LCNF) from Musa basjoo pseudo-stems, a relative of bananas, without the need for extensive drying. Instead, wet pseudo-stems were compressed and treated with NaOH solutions at varying temperatures and durations. The extracted material exhibited the characteristic peaks of cellulose I in X-ray diffraction (XRD) patterns, similar to those obtained from dried pseudo-stems. Fourier-transform infrared (FT-IR) spectroscopy confirmed the presence of cellulose I in the treated material and lignocellulose nanofiber clearly shown at 1600-1500, 1421, 1365, and 1161 cm-1. Composition analysis by Van Soest fiber analysis revealed a higher cellulose content in the treated material of wet pseudo-stems compared to that obtained from dried pseudo-stems, indicating the effectiveness of this low-energy extraction method. Meanwhile, field-emission scanning electron microscopy (FE-SEM) images demonstrated clear LCNF in the nanometer scale fibers after NaOH treatment. Overall, this study successfully demonstrated the extraction of LCNF from wet pseudo-stems of Musa basjoo with NaOH treatment at 70°C for 3 hours with 80% extraction result, providing a more efficient and low-energy approach for utilizing waste from Musa basjoo and bananas.

This study evaluated the efficacy of optimized autoclave-assisted seawater (A-SW) and microwave-assisted seawater (M-SW) pretreatments in improving sugar production from banana pseudostem. Subsequently, the structural changes of banana pseudostem, along with inhibitory compound concentrations were assessed under the conditions optimized for A-SW and M-SW pretreatment models. High coefficient of determination (R2) value (> 0.82) was obtained for both A-SW and M-SW. In addition, comparable reducing sugar of 0.41 ± 0.01 g/g and glucose yield of 0.24 ± 0.001 g/g were obtained from the optimized A-SW pretreatment, compared with the reducing sugar yield of 0.23 ± 0.004 g/g and glucose yield of 0.14 ± 002 g/g from the optimized M-SW regime. Furthermore, the A-SW high pretreatment efficiency was confirmed by changes in the biomass structure and low concentration of inhibitory compounds. Therefore, the potential use of abundant and sustainable seawater-based in this study with different heating mechanisms for pretreatment of lignocellulosic biomass provides a novel strategy to reduce the costs associated with the application of chemicals and scarce fresh water in lignocellulosic biorefineries.
