【摘要】：正母乳为宝宝提供了主要营养元素,同时也有益于寄生在婴儿胃肠道中的微生物。近日,刊登于《细胞-化学生物学》期刊上的研究显示,长双歧杆菌能通过产生一种名为LnbX的酶,成功适应婴儿肠道环境。这一机制使得该细菌能以仅在人奶中富含的糖类为食。"基于双歧杆菌能促进健康,我们的研究可能揭示了母乳驱动的肠道细菌和人类共生的进化轨迹。"该论文共同高级作者、日本京都大学的Takane Katayama说。早期肠道细菌被认为对人体健康有长效影响,并且膳食会对肠道菌群产生巨大影响。例如,科学家
[Abstract]:Breast milk provides babies with the main nutrients and also benefits microbes that parasitize the gastrointestinal tract of infants. A recent study published in the Journal of Cellular Chemical Biology shows that. Bifidobacterium can successfully adapt to the intestinal environment in infants by producing an enzyme called LnbX. This mechanism allows the bacterium to feed on sugars that are rich only in human milk. "Bifidobacterium can promote health," he said. Our research may reveal the evolutionary trajectory of breast-milk driven intestinal bacteria and human symbiosis, "said Takane Katayama, co-author of the paper at Kyoto University in Japan. Early intestinal bacteria are thought to have long-term effects on human health. And diet can have a huge impact on the intestinal flora. For example, scientists
