Role of mechanical vs. Chemical Action in the removal of adherent Bacillus spores during CIP procedures
Food Microbiology, 2013Co-Authors: Christine Faille, Thierry Benezech, W. Blel, A. Ronse, G. Ronse, M. Clarisse, Christia SlomiannyAbstract:This study was designed to evaluate the respective roles of mechanical and Chemical effectson the removal of Bacillus spores during cleaning-in-place. This analysis was performed on 12 strainsbelonging to the B. cereus group (B. cereus, B. anthracis, B. thuringiensis) or to less related Bacillusspecies (B. pumilus, B. licheniformis, B. sporothermodurans, B. subtilis). Adherent spores weresubjected to rinsing-in-place (mechanical Action) and cleaning-in-place (mechanical and Chemicalresistance to shear was not related to spore surface properties. Conversely, in the presence of NaOH atdetached during CIP and the Chemical Action greatly depended on the strain. This finding suggests thatChemical Action plays the major role during CIP, whose efficacy is significantly governed by the sporesurface chemistry.

Role of mechanical vs. Chemical Action in the removal of adherent Bacillus spores during CIP procedures
Food microbiology, 2012Co-Authors: Christine Faille, Thierry Benezech, W. Blel, A. Ronse, G. Ronse, M. Clarisse, Christia SlomiannyAbstract:This study was designed to evaluate the respective roles of mechanical and Chemical effects on the removal of Bacillus spores during cleaning-in-place. This analysis was performed on 12 strains belonging to the Bacillus cereus group (B. cereus, Bacillus anthracis, Bacillus thuringiensis) or to less related Bacillus species (Bacillus pumilus, Bacillus licheniformis, Bacillus sporothermodurans, Bacillus subtilis). Adherent spores were subjected to rinsing-in-place (mechanical Action) and cleaning-in-place (mechanical and Chemical Actions) procedures, the latter involving NaOH 0.5% at 60°C. Results revealed that mechanical Action alone only removed between 53 and 89% of the attached spores at a shear stress of 500 Pa. This resistance to shear was not related to spore surface properties. Conversely, in the presence of NaOH at a shear stress of 4 Pa, spores were readily detached, with between 80 and 99% of the adherent spores detached during CIP and the Chemical Action greatly depended on the strain. This finding suggests that Chemical Action plays the major role during CIP, whose efficacy is significantly governed by the spore surface chemistry.

Electrical Signatures for Chemical Action at the Work Surface in an Oxyfuel Flame
Volume 3: Manufacturing Equipment and Systems, 2018Co-Authors: Christopher Reed Martin, Joseph Kinney, Andrew Matzik, Jessica MolinaAbstract:An oxyfuel cutting torch was biased with a positive DC voltage relative to steel and copper work pieces, and ion currents were seen to flow due to ions generated Chemically in the flame and at the work surface. A repeatable 150% rise in these currents occurs over steel at a surface temperature around 1050°C. Equally strong intermittent spikes appear over clean and corroded steel samples alike. They are are easily removed by a median value filter, and are believed to be due to small reacting particulates. Tests in which salt was deliberately deposited on the steel surface produces a signal similar in shape, but exaggerated in magnitude to those currents supposed to be from other surface impurities.

A study of ion currents in an oxyfuel flame due to work surface Chemical Action
Experimental Thermal and Fluid Science, 2018Co-Authors: Christopher Reed MartinAbstract:Abstract Experiments controlling for work surface temperature and Chemical activity under an oxyfuel cutting torch flame reveal that ion currents in the flame can double or even triple due to Chemical Action at the work surface. Steady-state experiments over copper coupons with various diameters at various temperatures are compared against transient experiments over steel plates with various surface conditions. In extreme cases, steel samples are coated with salts, and the effect is exaggerated by an order of magnitude. These measurements demonstrate that there are two sources of ions in the system; the Chemical reAction in inner cone and the work surface. A number of plasma properties are estimated from measurements show good agreement with prior measurements in simpler geometries. These form the basis for an argument in favor of a simplified flame model proposed in the conclusions.
