Cryopreservation and Freeze-Drying of Fungi,Many aspects of mycology today necessitate living cultures. Traditional taxonomy is being supplemented by molecular biological techniques often requiring growing organisms. The need to keep particular strains for confirmation of results, further studies, and as references is well established.

Freeze-Drying and Cryopreservation of Bacteria,rovide varying degrees of success with different species of bacteria, and neither technique results in 100% recovery of preserved cells (.). There is no universally applicable method for the successful preservation of all bacteria, and where it is vitally important that cultures are not lost, it is advisable to use both methods in parallel.

Freeze-Drying of Yeasts,on, under the terms of the Budapest Treaty (1977), has increased the demand for the maintenance of microorganisms in designated culture collections. As with other microorganisms, long-term preservation methods are required that ensure survival of the strain and the retention of any characteristics of commercial value.
