- ... The combined effect of ultrasonic (20 KHz, 150 W) and heat treatment on the survival of two strains of Bacillus subtilis in three suspending media (distilled water, glycerol and milk) has been studied. When spores suspended in water or milk were subjected to ultrasonic waves before heat treatments a little or no decrease of the heat resistance was observed. However, both sporicidal agents applied ...

- ... The thermal inactivation of Salmonella thompson, Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Candida zeylanoides, Enterococcus faecium and E. faecalis was accelerated by the addition of sodium isoascorbate (1 mmol/1) to phosphate-buffer heating medium but not to complex food mixtures. The lethal effect of isoascorbate was nullified by heating under anaerobic conditions or by ...
