Chemical Composition of Myrtus communis L. (Myrtaceae) Fruits

The chemical composition of Myrtus communis L. extracts were prepared and analyzed by GC-MS. Sixteen phytochemical constituents of chemical compounds were identified in fruits of Myrtus communis. The relative percentage of linoleic acid methyl ester was high (27.19%), followed by oleic acid methyl ester (21.18%) and then octane 3,5- dimethyl (16.47%), dodecane (11.39%), palmitic acid…

Copper Nanomaterials as Delivery System in Combating Infective Agents and Cancer

Infectious diseases portend serious threat hazards to public health globally due to the development of the resistance to broad spectrum antimicrobials, the emergence of multidrug resistant biofilms, the drug side-toxicity, the non-specificity of drug targeting and the inability to overcome biological barriers. In this context, nanotechnology-based metal nanoparticles have attracted attention as nanomedicine against different…

Keratin Degradation by Penicillium purpurogenum and Aspergillus niger Isolated from Nigerian Soils Polluted with Tannery Wastes

Background: Keratinophilic fungi are a group of fungi that colonize various keratinous substrates and degrade them to components of low molecular weight. Keratinized tissues include feathers, beaks of birds, horns, hooves, skins, hair, fur, wool, nails and claws of animals. Tannery soils are very rich in keratinous materials such as fur, wool and hair that…

Synthetic Elicitor-Induced Defense Responses in Tomato (Solanum lycopersicum) Cultivated in Côte d’Ivoire against Bacterial Wilt Caused by Ralstonia solanacearum

Tomato is the most consumed vegetable in Côte d’Ivoire because it is used to cook most sauces and all forms of salad. Tomatoes annual yield fluctuates between 22,000 and 35,000 tons. The yield remains below demand. Several factors can explain these low yields. Among them, biotic factors are the most important. Among bacterial diseases impacting…

Physicochemical Properties of an Avian Protease Inhibitor

Background: Ovomucoid is a serine proteinase inhibitor in the egg whites of all avian species at a concentration of about 10 mg/ml. The involvement of proteinases in a multitude of control functions in an organism has created an interest in their physiological inhibitors. Regulation of proteolytic activity in tissues is a critical requirement in the…

Fatty Acid Methyl Ester Analysis of Olive Oil Degraded by Pseudomonas fluorescens and Enzymatic Characterisation of the Lipase

Vegetable oils are harmful to the environment, like petroleum oils they produce similar environmental effects. Hence, it is a known fact that the olive oil causes the production of large quantity of olive mill waste (OMWs) as by-products to the environment. These by-products are harmful to the environment, both  terrestrial  and  aquatic.  Bacteria  are  very …
