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.
