3600岁的中国kefir奶酪DNA提取 揭示出来自北高加索以外地区 3,600-year-old Chinese kefir cheese DNA extract reveals origin outside North Caucasus.
在*Cell* 上公布的一项研究表明,科学家从中国塔里姆盆地发现的大约3 600年前的古代奶酪样本中提取了DNA。 A study published in *Cell* reveals that scientists have extracted DNA from ancient cheese samples, approximately 3,600 years old, found in China’s Tarim Basin. 奶酪被确定为Kefir, 奶酪含有牛和山羊DNA, 并质疑Kefir只起源于北高加索的信念。 Identified as kefir, the cheese contains cow and goat DNA and challenges the belief that kefir originated solely in the North Caucasus. 这项研究揭示了益生菌的进化, 表明这些微生物如何在数千年内适应人类宿主. The research sheds light on the evolution of probiotic bacteria, indicating how these microbes adapted to human hosts over millennia.
