Improved agar gradient-plate technique.
MIC of antimicrobial compounds, it is essential to have uniform microbial growth on the agar medium; otherwise, it is difficult to determine a sharply defined area of growth inhibition. The conventional agar gradient-plate method has been found to be unsatisfactory for determining the MIC of chemotherapeutic compounds or antibiotics which inhibit filamentous fungi because the latter frequently ...
متن کاملStudies with the Agar Cup-Plate Method: I. A Standardized Agar Cup-Plate Technique.
Official Circular 198 (Ruehle and Brewer, 1931) gives directions for performing the agar cup-plate test. However, in the limited literature dealing with the subject, no mention is made of the influence of varying the volume of agar, the amount of inoculum, the hydrogen ion concentration or other factors. In the course of other studies with the agar cup-plate method (Rose and Miller, 1939; Mille...
متن کاملImproved susceptibility disk assay method employing an agar overlay technique.
Susceptibility disks impregnated with 35 different antibiotics were assayed by the current Code of Federal Regulations method and by a new method employing an agar overlay. The new method, a simplified analytical procedure, exhibited improvement in zone definition and an increase in dose response. Assays performed by the new method were accurate and precise. The agar overlay technique appears t...
متن کاملImproved agar bottle plate for isolation of methanogens or other anaerobes in a defined gas atmosphere.
A bottle plate for the cultivation of methanogens or other organisms in a defined pressurized-gas atmosphere was developed. The bottle provides the convenience of an agar streak plate, solves the problem of the water exudate from agar medium, and provides a convenient way of adding or sampling a defined gas atmosphere.
متن کاملAn improved agar-plate method for studying root growth and response of Arabidopsis thaliana
Arabidopsis thaliana is a widely used model plant for plant biology research. Under traditional agar-plate culture system (TPG, traditional plant-growing), both plant shoots and roots are exposed to illumination, and roots are grown in sucrose-added medium. This is not a natural environment for the roots and may cause artifact responses. We have developed an improved agar-plate culture system (...
