我打算测一下 发酵液的抑菌活性，原来在德国用的是“Rotilabo®-test flakes Untreated cellulose flakes for impregnating with active ingredient solution. Suitable for determining resistance to antiobiotics or chemotherapeutic media in bacteria culture and pathogenic organisms. Made of 100 % cotton linter, good absorption, grammage: 290 g/m2, thickness: 0.75 mm.” 不知道哪位大侠知道 国内哪里有卖？谢谢！
