Abstract

Coir bristle fibers were known for their lignin content and hardness level; they are commonly used in floor mats and traditional ropes. This
research proposes the application to soften and partially degrade the coir fibers through an eco-friendly approach, providing a more sus�tainable alternative to chemical treatment. The coir bristle fibers were pretreated, washed, and sterilized mechanically to eliminate surface
contaminants. The organism that exhibited the property of lignocellulose degradation was further considered throughout this research. The
isolated and highly efficient strains were subjected to biochemical characterization followed by their treatment against the identified bristle
coir fibers. Based on the incubation time, the post-treatment included neutral washing and drying of the fibers, and a comparative analysis
was performed among the two identified strains. The Bacillus, Pseudomonas spp were cultured and inoculated into the fibers under con�trolled conditions, and based on the degradation results obtained, Bacillus spp showed better results than Pseudomonas spp. Hence, Bacillus
spp was considered for a high-throughput technique as a 16S RNA sequence to arrive at species-level identification. This eco-friendly
treatment lowers the environmental impact of fiber softening and enhances the physical characteristics of coir bristle fibers for advanced
applications. The new method shows a promising route to the biotechnological valorization of coir and paves the way to integrate coir into
biodegradable composites and sustainable textiles
