啤酒酵母与几种乳酸细菌互生关系的初探

Tentative Research on Mutuality of Saccharomyces cerevisiae and Some Lactic Acid Bacteria

研究了啤酒酵母与保加利亚乳杆菌、植物乳杆菌、嗜热链球菌在人工培养条件下的互生作用,测定了互生培养的生长曲线及产气性能、互生过程中基质的酸度变化。结果表明这种互生关系对双方的生长均有利,基质中的细胞总数较单独培养大为增加。互生培养促进了酵母茵的代谢活性及产气指数。提示,啤酒酵母和乳酸细菌的互生作用在食品发酵工业中具有重要意义及广阔的应用前景。

Studied the mutualism of Saccheromyces cerevisiae and some Lactic Acid Bacteria under artificial conditions.And measured the living curve,the producing gas function and Ph changeable of the medium in the process.The results indicates that the mutualism is profitable for each other,and the sum of cells increases highly than single cultivation. The mutualism promotes the metabolism of Saccheromyces cerevisiae and its-index number of producing gas.Then the mutualism of Saccheromyces cerevisiae and Lactic Acid Bacteria can be widely applied in food ferm- entation industries.
