Fabrication and Characterization of EPS Mediated Nanofiber Production by Marine Actinobacteria 13HB (Streptomyces Sp.,) and their Antibacterial Potential
Year: 2024
Type: article
Abstract: The marine actinobacterial strain 13HB, identified as Streptomyces sp., produces extracellular polymeric substances (EPS) with promising applications. Morphological analysis observed yellow aerial mycelium with no melanoid pigment but soluble pigment production. Chemotaxonomical observations indicated the absence of arabinose, galactose, xylose, madurose, and ribose, with the cell wall containing LL-DAP and glycine. Scanning electron microscopy (SEM) showed EPS-mediated nanofibers with smooth surfaces, consistent diameters, and a dense network structure. Fourier-transform infrared spectroscopy showed the functional groups such as hydroxyls, carboxylic acids, and aromatic compounds, enhancing the fibrous structural properties. Antibacterial activity demonstrated significant inhibition of Escherichia coli growth by the EPS fibrous membrane, while Pseudomonas aeruginosa showed less susceptibility. These findings suggest that EPS-mediated nanofibers from Streptomyces sp. 13HB exhibit potential for biomedical and environmental applications due to their structural integrity, functional group diversity, and antibacterial properties.
