Pure cultures for home hobbyists with small labs or commercial farms needing a new strain, Mushroom Mountain now offers sterile test tube slants (50 ml centrifuge tubes) of our select mushroom strains at the generation number, G-5 or lower, for cultivation or research.
Tubes are 50mL plastic sterile centrifuge tubes with a twist cap, contain 25ml of malt extract agar and an antibiotic to limit bacterial growth during storage. The slants are made to order weekly and shipped after allowing them to colonize for one week at 28 degrees C.
All slants are marked with waterproof labels noting strain, generation numbers, and storage media, parafilmed around the screw cap, and ziplocked for shipment. Tubes are delivered in a 1”insulated foam box that contains a pharmaceutical cold dry pack to limit condensation while maintaining cool temperatures during transport in warmer months. Tropical species and winter shipments will not be shipped with a cold pack, rather using the insulation as a means of protection from freezing.
These tubes, if maintained under refrigeration, can last several years before you need a replacement. Tradd’s new book, Organic Mushroom Farming and Mycoremediation has a complete chapter on laboratory techniques to help you make the most of these pure cultures.
