The preparation of DNA by alcohol precipitation in the presence of Na1 was used to enable the direct detection of Listeria monocytogenes in the amount of 10(3) CFU/0.5 g of sample. This procedure produces PCR-quality DNA directly from foods, such as soft cheese and minced meat.
在存在Na1的情况下通过乙醇沉淀制备DNA,用于直接检测每0.5克样品中10(3) CFU的单核细胞增生李斯特菌。此方法可直接从软奶酪和碎肉等食品中制备出适用于PCR的DNA。
