Study on Mechanisms of Escherichia coli Growth Stimulated by Yeast Extract and Echlonia Kurome Okum Water Extract
酵母提取物和海带水提液促大肠杆菌生长机理初步研究

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.
