Ameliorative effect of Lentinus squarrosulus mycomeat against Pseudomonas aeruginosa infection using albino rat as animal model
The increasing awareness of inherent therapeutic and prophylactic benefits of some higher fungi and their products has been the recent trend for improving a healthy vigour. Mycomeat is a mushroom derived ‘meat-like’ product produced using solid state fermentation technique. Previous research in this group revealed mycomeat as a potentially useful neutraceutical. This study seeks to explore the potential of...
Efficacy of chitosan supported organic acaricide extract from Melia azedarach leaves on Rhipicephalus (Boophilus) microplus ticks
The Rhipicephalus (Boophilus) microplustick control is mainly performed by chemicals products, but organic acaricides use has higher advantages compared to conventional products. Brazilian cerrado native plants are known for their bioactive potential. Due to this fact, the objective of this study is to evaluate the acaricide action of native cerrado specie, Meliaazedarach, known as Santa Barbara in the tick control....
Optimization of alkaline protease production by Streptomyces sp. strain isolated from saltpan environment
Proteolytic activity of a Streptomyces sp. strain isolated from Ezzemoul saltpans (Algeria) was studied on agar milk at three concentrations. The phenotypic and phylogenetic studies of this strain show that it represents probably new specie. The fermentation is carried out on two different media, prepared at three pH values. The results showed the presence of an alkaline protease with optimal pH and temperature of 8 and...
Recovery of silver from used X-ray film using alkaline protease from Bacillus subtilis sub sp. subtilis
Silver is an important industrial metal used in several areas such as photographic and x-ray films, jewelries, silver wares and electronic objects. Silver is used for photographic film/x-ray film because of its matchless quality as a light-sensitive material for making a photographic image. Silver is not destroyed in the photographic process and it can be reused and recovered. Results have proven that, bacterial...
Flow cytometry approach for studying the interaction between Bacillus mojavensis and Alternaria alternata
Tomato, Solanum lycopersicum is one of the most important vegetable crops consumed in Algeria. Tomato crops are often infected by Alternaria alternata, which causes early blight disease. Chemical pesticides are intensively used to protect this plant, which lead to environmental pollution that might endanger animal and human health. The main objective of this study is to select potential biocontrol agents from arid soil...
