Preservation of Nocardia sp. cultures on porous beads

Coating of sterile glass beads with certain bacteria has provided a simple method for their low temperature storage. This procedure was applied to Nocardia sp., filamentous bacteria which are maintained by subculture on Sabouraud dextrose agar especially in clinical laboratories. The coating of glass beads by Nocardia sp. resulted in an easy and effective method to preserve the microorganisms at -76 degrees C.
