Vii. the Penetration of Electrolytes into Gels. I. the Penetration of Sodium Chloride into Gels of Agar-agar

Surface sampling with an agar spray technique.

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 ...

Studies 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...

The Introduction of Agar-agar into Bacteriology.

Among fundamental developments in bacteriology the elaboration of solid culture substrates will always hold first place. With the introduction of a method for isolating micro6rganisms and growing them in pure culture, bacteriologists possessed the means for studying what Ferdinand Cohn (1872) called "Die kleinsten lebenden Wesen." Credit for the discovery of the solid medium technique is common...
