Seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. Despite the diversity in quality and quantity of the Mediterranean Tunisian coast flora, with its large contains of marine organisms and seaweeds, most of them have not yet been ...

Nanocomposites assembled with TiO2 and graphene were synthesised under solvent free conditions. The calcinated nanocomposites have been characterized by PXRD, SEM-EDAX, HRTEM Nitrogen adsorption-desorption techniques. Nanotitania was found to be formed in anatase phase larger surface area (268.2 m2g-1) increase content, the absorbance increased towards visible region. Their biological applicabi...

background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...

This study investigated the chemical composition, and antimicrobial and anti-wood-decay fungal activities of the essential oil isolated from the leaf of endemic Machilus zuihoensis Hayata, Lauraceae, of Taiwan. The essential oil from the fresh leaves of M. zuihoensis was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. A total of 104 compoun...

This study investigated the chemical composition, and antimicrobial and anti-wood-decay fungal activities of the essential oil isolated from the leaf of Litsea acuminata (Blume) Kurata from Taiwan. The essential oil from the fresh leaves of L. acuminata was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC–FID and GC–MS. A total of 48 compounds were identif...

Mycorrhizal spores were found to be closely associated with bacteria on their spore wall surface known as mycorrhiza associated bacteria (MAB) and its play a major role in the plant growth promotion by production of many known and unknown metabolites, nutrient solubilization and suppression of many soil borne pathogens in rhizosphere of crop plants. The present study was carried out to understa...

The study of lipopeptides and their related compounds produced by various living organisms from bacteria to marine invertebrates is fundamental interest for medicinal chemistry, pharmacology, practical clinical medicine. Using the principles retrosynthetic analysis linear cyclic peptides, pharmacological activity unique, unusual, rare fatty acids (FA) that are part natural was investigated. To ...
