Living, actively growing, axenic Agaricus bisporus cell culture, entirely free of other strains or contaminating organisms, for further multiplication. Our pure cultures are custom-made and produced fresh after ordering in a class 100 clean room environment on a solid culture medium (MEA) based on vegetable raw materials, it needs around 2 to 3 weeks until the culture is mature enough for shipping. The culture is supplied in special cell culture flasks (Filling volume: 15 ml culture medium, Growth area: 25 cm², Measurements: L x W x H = 79,7 x 42,6 x 26,53 mm) with breathable, hydrophobic membrane. This special design prevents introduction of contaminants and enables optimum gas exchange thanks to the high air flow rate of the membrane. In this packaging the mushroom culture can also survive longer shipping distance and time without loss of quality or germinative ability.
