The invention relates to a method for killing microorganisms (10), in particular bacteria, viruses, single or multicellular organisms, individual cells or the like, in which the microorganisms (10) are subjected to an alternating voltage (20) and excited to vibrate become. DOLLAR A The AC ...
and heating is still one of the most popular ways to kill microorganisms. ... High heat combined with high moisture is one of the most effective methods of killing microorganisms.
Pasteurization of foods and beverages is aphysical change. Pasteurization process was invented by Louis Pasteur in 1864. ... The process involves killing of the bacteria and microbes which cause fermentation of the food and beverages. What is the process of pasteurization? Pasteurization is theproces...
The results of this study clearly indicate that the killing of microorganisms caused by pulsed electric fields is related to electric field strength, the duration and number of applied pulses. The survival rate of E. coli, L. innocua, L. mesenteroides and S. cerevisiae decreases when any one...
The present invention relates to a process for sterilization or disinfection of any organic substances, or substances with organic constituents containing microorganisms, bacteria, fungi or spores, which substances do not themselves offer suitable conditions for spore germination, such as intestines... ...
of these species traverse that barrier in order to effectively kill all microorganisms on a medical device enclosed within the pouch. Relevant oxidizing species can be obtained by plasma discharging diatomic gases like oxygen, nitrogen, halogens, or binary mixtures of oxygen and hydrogen, oxygen and...
The other two methods of preservation do not require a fermentation step. One method is by direct pasteurization. In this method, the cucumbers are bottled and then exposed to very high temperatures for a set amount of time. This has the effect of killing all of the natural bacteria that ma...
Microorganisms were used for green synthesis of NPs. Actinomycetes includingStreptomycessp. are commonly employed in the synthesis of NPs due to their capacity to produce diverse bioactive secondary metabolites and extracellular enzymes15,16,17,18,19. Additionally, algal pigments1,2, algal derived solub...
As bacteria does not die instantly, time is a crucial factor, which is why a minimum time is needed in order to eliminate them all. The parameter is linked closely to temperature as the killing effect (death value/lethality value) is dependent on both....
Sterilization is the process of killing or removing microorganisms from a product to help ensure that it is sterile. In some embodiments, sterilization may include one, two, or more of dry heat sterilization, moist heat sterilization (steam), sterilization using electromagnetic energy (including, for...
