Several species of Magnetotactic bacteria have been discovered recently. These bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. These particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. Magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...

چکیده توان بالقوه تجاری سلولازها و کاربردهای گوناگون آن ها در بسیاری از صنایع انگیزه ای قوی برای تحقیق در این زمینه طی چند دهه گذشته بوده است. با توجه به کاربردهای فراوان این آنزیم در صنایع غذایی? در این پژوهش تصمیم به جداسازی ریزسازواره های تولید کننده سلولاز از خاک درختان انار، انگور، خرمالو و گردو حیاط دانشکده کشاورزی تربیت مدرس، گرفته شد. در این بین خاک درخت خرمالو به دلیل دارا بودن تعداد ...

Indigenous acidophilic bacteria separated from mine-waste can be used in return for the addition of the reagents like sulfuric acid. Among the tailings bacteria, Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans are of the most-studied ones for the bioleaching and bioremediation of elements. In this work, the isolation and characterization of the mentioned bacteria are studied by...

conclusions this paper may serve as a guide to screening, isolation, and cultivation of more new mtb. the new isolated strain opens up good opportunities for biotechnological applications such as medicine to bioremediation processes due to its unique abilities. results the results revealed a correlation of important physicochemical factors such as ph and iron with growth and blooms of these bac...

Background: Among pathogenic bacteria, Gram-negative bacteria are more important. The secreting outer membrane vesicles of the bacteria are important role in physiology, virulence, and the interaction between host and pathogen. These vesicles allow bacteria to transmit enzyme and its contents as conserved form and also these involved in viability. Since they are represented as bacteria candidat...
