In package inactivation of Bacillus atrophaeus spores using high voltage atmospheric cold plasma
Introduction: Hospital acquired infections are of a great concern, considering a large number of infections reported every year. Sterilization is an important step in healthcare industry that is attained by utilizing conventional sterilization approaches. It includes heat treatment, use of chemicals like ethylene oxide, hydrogen peroxide, and gamma radiation. These methods have drawbacks such a...
متن کاملBioactivity Determination of Recombinant lysostaphin Immobilized on Glass Surfaces Modified by Cold Atmospheric Plasma on Staphylococcus aureus
Introduction: Staphylococcus aureus is a source of nosocomial infections and one of the significant concerns in patients with indwelling devices. Lysostaphin is a bacterially produced endopeptidase with a unique activity on S. aureus. Plasma, the fourth state of the material, consists of charged ions, free electrons, and activated neutral species. Biomedical applications of cold plasma are rapi...
متن کاملAtmospheric plasma inactivation of foodborne pathogens on fresh produce surfaces.
A study was conducted to determine the effect of one atmosphere uniform glow discharge plasma (OAUGDP) on inactivation of Escherichia coli O157:H7, Salmonella, and Listeria monocytogenes on apples, cantaloupe, and lettuce, respectively. A five-strain mixture of cultured test organisms was washed, suspended in phosphate buffer, and spot inoculated onto produce (7 log CFU per sample). Samples wer...
متن کاملMicrobial Decontamination of Spices Using Cold Plasma
Most of spices are produced using traditional systems. In unsanitary conditions, spices can contain large numbers of pathogenic microbes such as bacteria, molds and yeasts. Some microorganisms are known as human pathogens, which need disinfection mechanisms that minimize their potential harms to active substances in spices. Use of contaminated spices in foods can significantly decrease the shel...
متن کاملUse of Raman Spectroscopy and Phase-Contrast Microscopy To Characterize Cold Atmospheric Plasma Inactivation of Individual Bacterial Spores.
UNLABELLED Raman spectroscopy and phase-contrast microscopy were used to examine calcium dipicolinate (CaDPA) levels and rates of nutrient and nonnutrient germination of multiple individual Bacillus subtilis spores treated with cold atmospheric plasma (CAP). Major results for this work include the following: (i) >5 logs of spores deposited on glass surfaces were inactivated by CAP treatment for...
