Analysis Performance of Ceiba pentandra Fibers/PVA Bioplastics for Antimicrobial

This paper develops the films from a blend of Ceiba pentandra fibers and polyvinyl alcohol and evaluates their effectiveness against the antimicrobial activity. The antimicrobial activity of bioplastics against Gram-negative bacteria such as E. coli and P. aeruginosa and Gram-positive bacteria such as S. aureus and B. subtilis was tested using the Agar-well diffusion method. Fourier Transform Infrared Spectroscopy and Field Emission Scanning Electron Microscope were used to focus on the characterization of bioplastics. For the antimicrobial test results, even though the bacteria of Gram- positive and Gram-negative were in the same group, the minimum inhibitory concentration values of the bacteria differed. Furthermore, the spectra were recorded from 400 4000 cm

. The findings demonstrate that the treated fibres exhibited a rough surface, pores, a larger diameter, and a strong bond with the Ceiba pentandra fibers/PVA. Additionally, untreated fibres have a smooth surface, no holes, a smaller diameter, and a looser bonding with PVA than treated fibres. As a result, creating novel bioplastics with antibacterial qualities may be a possibility for medical applications, particularly for wound healing.
