Further Investigations on the Preservation of Mold Cultures

Abstract

If a culture lends itself to lyophil preservation, we believe this to constitute the most reliable means of maintaining it in unaltered form over long periods of time. In the long run it is also the least time-consuming. If the culture cannot be so preserved, one must rely upon alternative methods. Preservation in soil offers certain favorable advantages, but this method—like lyophil preservation—is not applicable to the maintenance of mycelial forms. If the culture is strictly mycelial, or if very few spores are produced, preservation under oil generally affords the best means of conservation.
