Introduction It is nearly 30 years ago that the International Commission on Microbiological Specifications for Foods (ICMSF) provided urgently needed guidance on the use of sampling plans and microbiological criteria for foods in international trade. With publications like “Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications” (1) and now “Micro...

due to uncontrolled dump of dried municipal sludge and its use by farmers as soil conditioner and/or fertilizer, an extensive research was conducted in order to determine the microbiological characteristics of municipal sludges produced at three major cities, namely, qateef, dammam and khobar in the eastern province of saudi arabia. sludge samples were collected, from sand drying beds, twice a ...

In this research, the chemical and microbiological characteristics of white brined cheeses produced with five differen starter cultures, namely: traditional kefir grain, commercial kefir, commercial yogurt, traditional yogurt and commercial cheese starter culture, were examined during 60- day ripening period. Results of statistical analysis showed that the type of starter culture had a signific...

an agar well diffusion bioassay method for determination of clarithromycin in human plasma, using micrococcus luteus atcc 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (hplc) method with uv detection. spiked plasma was used to prepare standard and control samples for both methods. the results of the bioassay analyses with spiked plasma samples...
