The Influence of Electric Field on Microbial Growth
نویسنده
چکیده
The infl uence of alternating electric fi elds of various frequency levels (from 10 to 400 Hz) on the growth of various microorganisms was studied. It was shown, that electric fi elds with frequencies from 10 to 60 Hz were stimulating microbial growth, while higher frequencies were causing its inhibition. No growth of yeasts and streptococci was detected after 1 hr treatment with 400 Hz frequency electric fi eld. Such infl uence of the electric fi eld can be used in food production to prevent the development of undesirable microorganisms inside the equipment, in remote areas or during food processing. This also can be used for continuous sterilization or pasteurization of liquid or viscous food products.

In this research, the effect of the uniform electric field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot was studied using infinite potential model. In presence of strong electric field, due to the stark effect (perturbing electric field), the ground state energy would increase linearly. In presence of weak electric fields, the normalized bind...
متن کاملEffect of Cell Size and Shape on Electric Field Threshold and Critical Transmembrane Voltage for Electroporation
Introduction: Electroporation is a technique for increasing the permeability of the cell membrane to otherwise non-permeate molecules due to an external electric field. This permeability enhancement is detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the pulse strength threshold. In this study, the variabil...
