Rapid molecular techniques for detection of foodborne Bacillus cereus pathogen
Background and Objective: Bacillus cereus is responsible for several outbreaks of foodborne diseases. Therefore, the purpose of the study was to replace routine culture testing, by employing PCR directly from food to detect the bacteria and its enterotoxins. Methods: In the present study, a total of 75 Kibda sandwiches, Sausage sandwiches, Luncheon chicken, Luncheon meat and shawarma sandwiche...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولChemically defined media for cultivation of Naegleria gruberi.
Cultivation of amebae of the axenic strain of Naegleria gruberi, NEG-M, was achieved in media consisting entirely of chemically defined components. A complete medium that contains 31 components allows growth with yields up to 5 x 10(6) amebae per ml. A minimal medium gives lower yields but defines 22 components that are essential for continuous cultivation: 11 amino acids, 6 vitamins, hematin, ...
متن کاملIsolation and Optimization of Tobacco Decomposing Bacillus and Lactobacillus Sp.
Three bacteria from a tobacco industry effluent and one from a sewage sample were isolated on a medium comprising of 1% tobacco powder as sole source of nutrients. Bacteria isolated from the industrial waste water were identified as Bacillus cereus, B. alvei and B. circulans. While, Lactobacillus sp. was isolated from the sewage sample. The bacteria were optimized for various growth conditions ...
متن کاملOptimization of heterotrophic cultivation of Chlorella sp. for oil production.
The oleaginous microalga Chlorella sp. LAM-H screened from freshwater was proven to be a prospective feedstock for oil production according to its fatty acid composition. In order to enhance lipid production, response surface methodology (RSM) was used with central composite design (CCD) to optimize the heterotrophic cultivation of microalgae. The experiment results showed that a satisfactory s...
