Abstract

Specimen of mushrooms obtained from weimerian supermarkets are cloned and the developing strain is purified, than stored in a cold-storage strain-bank. Via reverse-engineering the strand from a commercial product is extracted and cultured. The strands will be available at an exhibition.

Method

For every attempt of cloning at least seven petri-dishes filled with PDA- medium are inoculated. The scalpel is sterilized in a hot flame till it glows red. It then is cooled in the receiving petri dish. The mushroom is ripped apart in the middle. Tissue then is taken from just above the gills, inside the stem or just under the cap. It is inserted in the hole that the hot scalpel made. The dishes are labeled and incubated at room temperature (23°-25° C). The mycelium that emerges is purified by running it through subsequent petri dishes till there is no visible evidence of contaminants. Then it is stored in test-tubes filled with PDA- medium at temperatures below 5°C. Two tubes per strand, enveloped in a zip-loc-bag.
