Photograms for microbiological assays.
The use of photograms provides a permanent record of microbiological assays in which diffusion of a substance in agar is measured. The accuracy of this procedure is comparable to direct measurement. This technique is inexpensive, does not require special photographic equipment, and is applicable to many tests commonly employed in clinical microbiology and immunology laboratories.
متن کاملAk Improved Medium for Microbiological Assays with Lactobacillus Case1
Since its introduction as an assay organism for riboflavin (I), Lactobacilhs casei has been widely used for the determination of this and other vitamins which it requires (2-6). I,andy and Dicken (3) devised a single medium with which responses to each of t.he six vitamins required by this organism could be obtained.

متن کاملDetection of mutagenic pollution of natural environment using microbiological assays.
One of the most important and serious ecological problems is mutagenic pollution of the natural environment. Therefore, detection of mutagenic compounds in samples taken from natural habitats is of special interest. Microbiological mutagenicity tests seem to be very useful tools for such detection. In this review article, a general view on the tests employing genetically modified bacterial stra...

متن کاملLiquid Nitrogen Freezing in Microbiological Assay Systems. Ii. Preservation of Sarcina Lutea for Antibiotic Assays.
The storage of Lactobacillus leichmannii in liquid nitrogen for direct use in the vitamin B12 assay was described by Sokolski, Stap)ert, and Ferrer (Appl. Microbiol. 12:327, 1964). This note describes a different ap)proach on treatment of data for stability of a test organism. A stable susl)ension of Sarcina lutea ATCC 9341, a bacterium used in many antibiotic assays, was obtained with storage ...
