酵母提取物和海带水提液促大肠杆菌生长机理初步研究

研究海带水提液和酵母提取物促大肠杆菌生长的机理。采用二维电泳 (2 DE)和生物质谱等蛋白质组技术对细菌的全蛋白质表达进行研究。发现 8种蛋白出现有规律的变化 ,其中 ,2种蛋白在对数期各组表达量均增高 ,4种蛋白在各组表达量下降且实验组下降更明显 ,1种蛋白在实验组表达量明显降低而对照组无明显变化。

Study on Mechanisms of Escherichia coli Growth Stimulated by Yeast Extract and Echlonia Kurome Okum Water Extract

To elucidate the mechanisms of yeast extraction and Echlonia Kurome Okum water extraction to stimulate the growth of Escherichia coli. Two-dimensional electrophoresis (2-DE) and bio-mass-spectrum were used to observe the changes of whole-protein expression caused by certain stimulants. It was found that the expression of 8 proteins changed in different ways. Two proteins leveled up but failed to be identified; 4 proteins declined much more in experimental groups than in control. There are some proteins participating to regulate growth of Escherichia coli.
