木耳提取物与乳酸菌混合发酵的营养价值及应用前景

Nutrition value and prospect of mixed fermentation of the black fungus extract and lactobacillus

胃肠道微生物生态系统是人和动物体内最复杂和最大的微生态系统,据估计成人胃肠道内共生着500~1 000种,1×1014个细菌,其数量是人体细胞总量的10倍。肠道菌群平衡失调会产生多种胃肠道疾病如腹泻、痢疾、炎症性肠病等,还会诱发肥胖、衰老、癌症、糖尿病、代谢综合症和心血管病等,严重影响人和动物的健康。因此,文章主要综述了乳酸菌属中的乳酸杆菌和双歧杆菌的功能、木耳浸提液的主要成分及功能,并对它们混合发酵的潜在价值进行了展望。

The gastrointestinal microbial ecosystem is the most complicated and largest micro-ecosystem of human beings and animals. It is estimated that there are nearly 500 to 1 000 kinds of bacteria with the num.ber of 1 × 1014 which is ten times the amount of human cells living in an adult's gastrointestinal tract. The dis.equilibrium of intestinal flora will lead to a variety of gastrointestinal diseases, such as diarrhea, dysentery, in.flammatory bowel disease and so on. It will also contribute to obesity, caducity, cancer, diabetes, metabolic syndrome, cardiovascular disease and so on, which has a strong impact on the health of human beings and ani.mals. Therefore, this article mainly reviews the function of lactobacilli andbifidobacterium inlactic acid bac.teria genera, the key component and the function of the black fungus extract and discusses the potential value of their mixed fermentation.
