Isolation and molecular identification of carotenoid-producing bacteria
The production of pigments from bacteria is significant due to the low cost, high yield and ease of extract compared with other sources. Carotenoids are one of the most important pigments with antioxidant properties which are the precursor of vitamin A synthesis and have antibody overproduction ability, anti-tumor activity and inhibitory effect on the cardiovascular disease. The present study a...
متن کاملChromosomes in Bacillus subtilis spores and their segregation during germination.
Spores of a thymine-requiring mutant of Bacillus subtilis 168 leucine(-), indole(-), thymine(-)) were uniformly labeled with (3)H-thymidine. These were seeded on thinlayer agar plates where they germinated into long-chained microcolonies. Autoradiograms were used to measure the distribution of labeled deoxyribonucleic acid in the chains of cells, which ranged in length from 2 to 32 cells. Four ...
متن کاملBacillus clausii probiotic strains: antimicrobial and immunomodulatory activities.
The clinical benefits observed with probiotic use are mainly attributed to the antimicrobial substances produced by probiotic strains and to their immunomodulatory effects. Currently, the best-documented probiotic bacteria used in human therapy are lactic acid bacteria. In contrast, studies aiming to characterize the mechanisms responsible for the probiotic beneficial effects of Bacillus are ra...
متن کاملIsolation and characterization of a metal ion-dependent alkaline protease from a halotolerant Bacillus aquimaris VITP4.
A halotolerant bacterium Bacillus acquimaris VITP4 was used for the production of extracellular protease. Fractional precipitation using ammonium chloride was used to obtain the enzyme. The protease exhibited optimum activity at pH 8.0 and 40 degrees C and retained 50% of its optimal proteolytic activity even in the presence of 4 M NaCl, suggesting that it is halotolerant. The molecular mass of...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
