The escherichia coli culture medium comprises 0.1g of glucose, 0.5g of peptone, 0.1g of KH2PO4*3H2O, 0.05g of MgSO4*7H2O, 0.33ml of rose-bengal solution, 1.5 to 2g of agar, 100ml of distilled water, 2ml of 2% deoxysodium cholate solution with a natural pH value, and 0.33ml of ...
E. coli was grown in chemostat culture so that cellular metabolism could be held in reproducible, steady-state conditions under a range of precisely defined growth conditions, thus enabling sufficient replication of samples. The metabolome profiles were generated using gas chromatography/time-of-flight...
Escherichia coli, when cultured on a simple medium containing only glucose and inorganic compounds, release soluble factors which have a variety of biologic effects on cells in vitro. These low molecular weight (less than 12,000) substances are capable of: a) reversibly inhibiting the migration of...
再将纯化后的打靶片段通过电击转化导入到E.coliW3110中,经菌落PCR验证,由图2A所示,片段1-5大小与阳性对照一致,证明Kan抗性成功替代了E.coliW3110菌株染色体上的甘油抑制因子的基因位置;之后通过导入pCP20质粒消除

Culture filtrates of Escherichia coli from patients with diarrhea were tested for the ability to cause accumulation of fluid in intestinal loops of rabbits and dogs. Strains that caused fluid accumulation in rabbits also caused it in dogs. The time course of the enterotoxic effect in dogs was ...
High cell-density culture of Escherichia coli Escherichia coli is the most widely used prokaryotic system for the synthesis of heterologous proteins. Once an optimal expression system has been construc... YL Sang - 《Trends in Biotechnology》 被引量: 1861发表: 1996年 加载更多来源...
(Fig.3e). We tested this experimentally by a bulk culture colony forming units (CFU) stress assay (see Methods section) and found the latter (Fig.4f). Furthermore, we observedrpoS-knockout cells that survived in the Mother Machine assay at 37 °C also down-regulated growth prior to ...

coli cells to high saline stress decreased the number of CFUs significantly. When the culture was relieved from the stressful condition, the number of CFUs returned within 2 hr to the same level as before the stress. This recovery in the number of CFUs seemed to be independent of DNA ...
