中文摘要 | 雙叉桿菌(bifidobacteria)是革蘭氏陽性菌,為人類固有的腸道菌,在腸道內生長及新陳代謝均良好,並維持腸道菌叢的生態平衡,影響健康甚鉅。據估計,人體消化道內的細菌高達10至100兆個,分佈最廣的是小腸之迴腸部份,而雙叉桿菌大部分存在於大腸的盲腸區域。腸道菌叢基本上分為有益及有害菌二類,當有害菌較多時,腸內有較多的氨、硫化氫、胺和酚類等有毒物質質,增加人體去毒組織的負菏,降低免疫能力。而有益菌,例如雙叉桿菌為優勢族群時,則因為產生醋酸及乳酸,降低腸道pH值,抑制有害菌的生長,減少它們對人體所造成的傷害。 不少文獻發現,雙叉桿菌能合成維生素B群、改善乳糖不耐症、更具有活化人體免疫系統及促進腸道蠕動,改善便秘的功能。近年來的研究已證實,雙叉桿菌經攝食後,能夠完整的到達腸道,且能長久棲息其間。因此,食品業已使用雙叉桿菌作為製造發酵乳的菌�Y(starter),期能維持或恢復腸道的正常菌叢,保障人體的健康。 |
英文摘要 | Normally present in the intestinal tract, bifidobacteria are Gram positive and maintain stable population which is essential for good health of human body. It is estimated that there approximately 10��-10�� bacteria in intestinal tract. There are very large numbers of bacteria in ileum, whereas, most bifidobacteria are present in caecum region. The functions of the intestinal microflora bacteria can be divded into useful activities and harmful activities. If harmful bacteria become predominant, there is an increase in toxic products of ammonia, sulfites, amines and phenol, overolading the liver involved in detoxication and lowering immunity. However, when present in large numbers useful bacteria, such as bifidobacteria may produce high concentration of acetic and lactic acids to lower pH and inhibit most harmful bacteria. Reports show that bifidobacteria may synthesize vitamin B complex, improve lactose intolerance, activate immune system and promote intestinal movements. Recent studies show that bifidobacteria, even after ingestion may arrive intact and alive in the intestinal tract. Bifidobacteria have been used as starter for various types of fermented milks in order to maintain normal intestinal microfolora that is good for health. |
