For the first time, an ultralight chitosan-glutaraldehyde nanofiber sponge (chitosan NF sponge) was prepared. The present work describes its processing from pure electrospun chitosan nanofibers and use for filtration applications. Chitosan/polyethylene oxide (PEO) (NF) were acetic acid into 309 ± 56 nm-thick using high-throughput free-surface electrospinning. To yield sponges, PEO extracted def...

Abstract In the present study, a commercial chitosan soluble in acid solution and obtained from shrimp shell waste, with molecular weight of 173 kDa degree acetylation 17%, named as (173/17), was investigated. Chitosan is well-known biopolymer whose antimicrobial properties are highly influenced by weight, well preparation derivatization methods used. (173/17) applied on grapevine leaves before...

The removal of polycyclic aromatic hydrocarbons from aqueous culture medium by the lignin-degrading marine fungus NIOCC # 312, obtained from decaying seagrass from a coral reef lagoon is reported here. We estimated the percentage of phenanthrene removed from the culture supernatant and the fungal biomass after 6 days. About 60-70% of phenanthrene, at a concentration of 12 mg l (12 ppm) was remo...

Marine organisms are constituted by materials with a vast range of properties and characteristics that may justify their potential application within the biomedical field. Moreover, assuring the sustainable exploitation of natural marine resources, the valorisation of residues from marine origin, like those obtained from food processing, constitutes a highly interesting platform for development...

Despite tremendous advances in medicine, there are no cures for some of the most deadly and crippling diseases. HIV/AIDS, arthritis, several types of cancer, and many viral and fungal diseases are some examples of horrible affl ictions that cannot yet be cured. There are also previously curable illnesses (e.g., strains of tuberculosis) that have become resistant to standard antibiotic therapies...

The purpose of this work was to screen the actinomycetes having antitumor or antimicrobial activity, which were isolated from the surface, epidermis and intestines of sea plants and animals collected from the Taiwan Strait, China. Antitumor activity was studied by the MTT assay and DNA target activity was studied by the biochemical induction assay while antimicrobial activity was determined by ...

Marine environments are unique habitats for microorganisms and represent uninvestigated areas that possess valuable resources. Fungi may also be important because they contribute to marine ecosystems as decomposers. The aims of this study were to investigate the halotolerance of marine-derived fungi and their enzymatic properties. Eighteen fungal strains representing 11 different species were u...

UNLABELLED Fungal cell walls are predominantly composed of glucans, mannans, and chitin. Recognition of these glycans by the innate immune system is a critical component of host defenses against the mycoses. Complement, an important arm of innate immunity, plays a significant role in fungal pathogenesis, especially the alternative pathway (AP). Here we determine that the glycan monosaccharide c...
