Abstract
Bio-nanotechnology provided an ecofriendly synth-
esis route for various metal nanoparticles by utilizing dif-
ferent biological systems, especially microorganisms, which
act as an alternative to the physical and chemical methods.
Cobalt nanoparticles (CoNPs) were synthesized by Periconia
prolifica (Anast.) from intertidal decayed wood samples from
the mangrove tree Avicennia marina (Forsk.) of Tarout Island,
located in the Arabian Gulf Sea of Saudi Arabia. CoNPs were
characterized by X-ray diffraction, transmission electron
microscopy, Fourier-transform infrared spectroscopy, and
atomic force microscope. The extract of the culture of
P. prolifica was used as a bio-reductant agent, during which
the culturing process proved to have great potential to be
applied on an industrial scale, as it was a time-saving, inex-
pensive, and adequate amount of biomass being produced at
the end of the process. A preliminary antibacterial test against
one Gram-positive resistant bacteria (i.e., Methicillin-resistant
Staphylococcus aureus) and other Gram-negative resistant
bacteria was performed using a disk diffusion assay. The
antibacterial results witnessed the key role that metal size
plays in causing higher activity and also in causing severe
damage to the bacterial cells by inactivating its membrane
permeability, leading to bacterial cell death.
