An Effective Use of Petri Dishes for Microcultures

R. Turner-Graff

Abstract

Summary: A microtechnique has been developed for the growth of many cultures in one Petri dish. The agar substrate is in the form of small plaques pipetted so that each plaque is distinct and separate from its neighbour in the Petri dish. The method is used for the assay of antifungal materials and has been adapted to the isolation and biochemical characterization of micro-organisms. Work is in progress to adapt the procedure to yeast and bacterial counts.
