What are emissions? Where do they come from?
Emissions is the term used to describe the gases and particles
which are put into the air or emitted by various sources.
Restaino et al (Restaino 1995) has shown that ozonated
water is highly effective in killing both gram positive and gram negative food associated
The Restaino study shows that ozonated water can effectively kill
spoilage organisms. (Pseudomonas aeruginosa and Zygosaccharomeyces bacilli), Faecal
contaminants (Enterococcus faecallis and Escherichia coli) and food bourne pathogens
(listeria monocytogenes, Bacillus cereus, Salmonella typhimurium, Yersinia enterocolitica
and Staphylococcus areus). More than 5 log reduction of Salmonella typhimurium and
Escherichia coli was reached instantaneously in ozonated water with or without the addition of 20 ppm of soluble starch.
Among gram-positive bacteria, listeria monocytogenes, was signifficantly
the more sensitive (5 log immediate reduction). More than 4.5 log units each of
Candida albicans and Zygosaccharomeyces bacilli cells were killed instantaneously
in ozonated water, whereas less than 1 log unit of Aspergillus niger spores were
inactivated after 5 minutes of exposure.
In the Restaino study, the gram negative bacteria were substantially
more sensitive to ozonated water than the gram positive bacteria either in the absence
or in the presence of added organic material.
