Mechanisms of dehydration injury in bacteria.
Author(s) : ASHWOOD-SMITH M. J.
Type of article: Article, IJR article
Summary
Genetic injuries caused by freeze-drying and desiccation are discussed. The experiments clearly demonstrate that the process of freeze-drying causes a variety of mutations in bacteria. The number of mutations increases as a function of the duration of cold storage. Breaks in DNA single strands were produced and, immediately after freeze-drying, the activation and formation of lambda bacteriophages from lysogenic bacteria was observed. It is clear that cryopreservation is better than freeze-drying for the long term storage of microorganisms when one requires absolute genetic stability.
