Screening of Bio-Surfactant Production Ability among Organic Pollutants Degrading Isolates Collected From Egyptian Environment

Effect of Various Culture Parameters on the Bio-surfactant Production from Bacterial Isolates

Biosurfactants are those compounds which contains both hydrophilic and hydrophobic moieties i.e., amphiphilic in nature. They have advantages over the chemical surfactant such as low toxicity, eco-friendly, etc. They possess wide range of industrial applications such as bioremediation, food processing, oil industries and health care. Various microorganisms have the ability to produce the potent...

Production of Persistent Organic Pollutants from Cement Plants

Production and Characterization of Keratinolytic Protease from New Wool-Degrading Bacillus Species Isolated from Egyptian Ecosystem

Novel keratin-degrading bacteria were isolated from sand soil samples collected from Minia Governorate, Egypt. In this study, the isolates were identified as Bacillus amyloliquefaciens MA20 and Bacillus subtilis MA21 based on morphological and biochemical characteristics as well as 16S rRNA gene sequencing. B. amyloliquefaciens MA20 and B. subtilis MA21 produced alkaline keratinolytic serine pr...

Screening for coeliac disease among Egyptian children

INTRODUCTION To screen for coeliac disease in Egyptian children with non-endocrinal short stature, refractory iron deficiency anaemia and type 1 diabetes. Also, to evaluate the sensitivity and specificity of different serological tests for diagnosis of coeliac disease (CD). MATERIAL AND METHODS The study included 292 patients with clinical risk of CD. Testing for coeliac antibodies was perfor...
