ABSTRACT The relationship between cell inactivation and membrane damage was studied in two gram-positive organisms, Listeria monocytogenes Bacillus subtilis , gram-negative Yersinia enterocolitica Escherichia coli exposed to chlorine the absence presence of 150 ppm organic matter (Trypticase soy broth). L. B. were more resistant distilled water. addition small amounts chlorination medium drastically increased resistance both types microorganisms, but this effect marked Y. E. . In addition,...
ABSTRACT A specially designed resistometer was constructed, and the lethal effect on Yersinia enterocolitica of ultrasonic waves (UW) at different static pressures (manosonication [MS]) combined heat-UW under pressure treatments (manothermosonication [MTS]) investigated. During MS 30°C 200 kPa, increase in amplitude UW 20 kHz from 21 to 150 μm exponentially decreased decimal reduction time values ( D ) 4 0.37 min. When increased 0 600 kPa a constant (150 μm) temperature (30°C), 1.52 0.20 The...

S. CONDÓN, A. PALOP, J. RASO AND F.J. SALA. 1996. The influence of the incubation temperature on estimated heat resistance for survivors after treatment was investigated. survival curves and Dt values spores Bacillus subtilis heated at different temperatures in pH 7 buffer, obtained incubating (30, 37, 44 or 51°C), were compared. influenced profile curves. Lower led to bigger longer shoulders. 30°C higher (x3 approx.) than those by 51°C. did not modify z (z= 9.1). These results show that...
The objective was to investigate the occurrence of sublethal injury after pulsed electric field (PEF) depending on treatment time, strength and pH media in two Gram-positive (Bacillus subtilis ssp. niger, Listeria monocytogenes) six Gram-negative (Escherichia coli, Escherichia coli O157:H7, Pseudomonas aeruginosa, Salmonella serotype Senftenberg 775W, Typhimurium, Yersinia enterocolitica) bacterial strains.A characteristic behaviour observed for bacteria studied. Whereas showed a higher PEF...
