Researchers have discovered an innovative and eco-friendly method for extracting natural fibers from banana pseudo-stems using seawater as a retting agent. This breakthrough could revolutionize the way we approach sustainable materials extraction, reducing the reliance on freshwater and offering a viable solution for arid regions. The study, published in the Journal of Bioresources and Bioproducts, explores the remarkable potential of this process and its implications for the future of natural fiber production. Banana and retting are key topics covered in this article.

Pioneering Seawater Retting: A Sustainable Revolution
In a groundbreaking study, researchers led by Prince Hotor from the Egypt-Japan University of Science and Technology have explored the use of seawater as a retting agent for banana pseudo-stems. Traditionally, the extraction of natural fibers from these plants has relied on freshwater retting methods, which consume significant amounts of a precious resource.
The team’s investigation into sustainable retting processes has uncovered a potential game-changer. By employing seawater, the researchers aimed to reduce the environmental impact of fiber extraction and offer a viable solution for arid regions where freshwater is limited. The study presents a comprehensive analysis of the seawater retting mechanism and its implications for the eco-friendly production of natural fibers.
Unlocking the Potential of Seawater Retting
The researchers conducted a series of experiments over a five-week period, closely observing the effects of different sterilization and non-sterilized conditions on the retting process. The results were highly promising, with the highest bacterial load and enzyme activity recorded in the second week of retting, indicating a robust biological process at work.
The study revealed that the seawater retting process could effectively remove lignin and other undesirable components from the banana pseudo-stems, enhancing the quality of the extracted fibers. Sophisticated analyses, including Fourier-transform infrared (FT-IR) and X-ray diffraction (XRD), confirmed the preservation of the fibers’ quality, with an increase in crystallinity index observed in all seawater retting treatment conditions.
Harnessing Microbial Power: The Secret to Successful Seawater Retting
The research team also identified several bacterial isolates with ligninolytic abilities, including strains of Bacillus velezensis, Shewanella sp., and Citrobacter amalonaticus, which play a crucial role in the retting process by breaking down the lignocellulosic components of the pseudo-stems.
These findings suggest that seawater retting could be a game-changer for the extraction of cellulosic fibers from banana pseudo-stems and potentially other lignocellulosic biomasses. This method not only conserves freshwater but also utilizes the abundant seawater resources, making it a sustainable and economically viable option. The study presents a significant advancement in the field of sustainable materials science, offering an innovative approach to fiber extraction that is both environmentally friendly and resource-efficient.
