It’s difficult to make predictions, especially about the future, and even more so when they involve the reactions of living cells — huge numbers of genes, proteins and enzymes, embedded in complex pat...
Consumption of un-pasteurized fruit juices has increased in recent years due to their freshness and other attractive characters. Contamination of those by pathogenic microorganisms is considered as on...
Bacteria are the major cause of surface water contamination in the United States. US Environmental Protection Agency (USEPA) uses the Total Maximum Daily Load (TMDL) process to regulate the E. coli lo...
The photosynthetic bacteria, Rodospirillum rubrum, produced hydrogen when grown in cheese whey in presence of light. The production increased three times as much when whey was used after being incubat...
将大肠杆菌E. coli ATCC8739置于12.0 T 超强静磁场(ultra-strong static magnetic field, SMF)中进行处理,获得了磁场处理0.5、1、2、4和8 h的菌株E. coli-SMFn(n=0.5、1、2、4、8)。在37℃、pH 7、静置的条件下,菌株对偶氮染料AR14 (I.C. Acid Red 14)的脱色结果指出,当反应进行到4、6和8 ...
A mediator microbial fuel cell (MFC) was constructed by using E. coli as biocatalyst and new methylene blue as electron mediator. E. coli cells were carried out in anaerobic growth prior to inoculatin...
通过正交实验考察了大肠杆菌E.coli HB101(pBR322)高密度培养过程中,不同培养条件对质粒的稳定性和β-内酰胺酶活力的影响. 结果表明,当温度在33~39℃、pH为6.4~7.2、DO为 40%~80%、 补料速率在5.4~10.8 g/h范围内变化,以及细胞密度达到27.3 g/L、比生长速率达到0.73 h-1时,质粒没有发生丢失现象,但在培养过程中β-内酰胺酶的活力降低. ...
The effect of chitosan and pressure of 193 MPa at –20 °C on Escherichia coli and Staphylococcus aureus cells suspended in a buffer at pH=5.8 as well as on the natural microflora of minced pork and app...
To research wider uses of the low temperature steam heating process, blade vegetables were heated by steam of temperature adjusted from 55°C to 80°C for 5-30 min. The treated vegetables were used for ...
The effects of pH, the major food ingredients sodium chloride, sucrose, protein and organic acids on Escherichia coli inactivation by hydrostatic pressure treatment with the addition of allyl isothioc...
The recovery of Escherichia coli IFO3301 injured by glycine (Gly) and/or ethanol (Et) was investigated. After treatment with 0.39 M Gly (Gly0.39) and 3 M Et (Et3), cells recovered in VSHINSKY broth (V...
Several pasteurization procedures for alfalfa (Medicago sativa) seeds were investigated to completely disinfect inoculated Escherichia coli (Migula) Castellani and Chalmers ATCC(25922). Hot-water trea...
The methods of sanitary inspection performed primarily by traditional culture methods are time consuming, laborious, and require complicated laboratory techniques. A number of instrumental methods hav...
An α-galactosidase gene belonging to glycoside hydrolase family 27 from Streptomyces coelicolor was cloned and expressed in E. coli. The purified enzyme showed a single protein band on SDS-PAGE with a...
The effect of the continuous flow of supercritical CO2 microbubbles (the SC-CO2 method) on the inactivation of both Escherichia coli in model water and coliform bacteria in water prior to treatment at...
