Gundersen (1962) created a disk cutter and therefore contains a stainless-steel tube regarding the 2 cm a lot of time and you may 0.3 mm dense out-of 6 mm inner diameter and you can try sharp into the during the one another ends up. A moment longer pipe, covered with rubberized at the end, is welded at the right angle to the reducing tubing in order to allow aseptic handling. Some other strange vaccination product was utilized by the Wilson (1957). He isolated fungi regarding soil examples.
