Re: Mold removal on CNN

[Guest guest]

Yes, chlorine gas does kill mold SPORES. BUT it does NOT inactivate

trichothecence mycotoxins.

AT ALL....

Effect of Chlorine Dioxide Gas on Fungi and Mycotoxins Associated with Sick

The growth of indoor molds and their resulting products (e.g., spores and

mycotoxins) can present health hazards for human beings. The efficacy of

chlorine dioxide gas as a fumigation treatment for inactivating sick

building syndrome-related fungi and their mycotoxins was evaluated. Filter

papers (15 per organism) featuring growth of *Stachybotrys chartarum*,

*Chaetomium

globosum*, *Penicillium chrysogenum*, and *Cladosporium

cladosporioides*were placed

in gas chambers containing chlorine dioxide gas at either 500 or 1,000 ppm

for 24 h. *C. globosum* was exposed to the gas both as colonies and as

ascospores without asci and perithecia. After treatment, all organisms were

tested for colony growth using an agar plating technique. Colonies of *S.

chartarum* were also tested for toxicity using a yeast toxicity assay

with a high

specificity for trichothecene mycotoxins. Results showed that chlorine

dioxide gas at both concentrations completely inactivated all organisms

except for *C. globosum* colonies which were inactivated an average of 89%.

More than 99% of ascospores of *C. globosum* were nonculturable. For all

ascospore counts, mean test readings were lower than the controls (*P* <

0.001), indicating that some ascospores may also have been destroyed. Colonies

of *S. chartarum* were still toxic after treatment. These data show that

chlorine dioxide gas can be effective to a degree as a fumigant for the

inactivation of certain fungal colonies, that the perithecia of *C. globosum

* can play a slightly protective role for the ascospores and that *S.

chartarum*, while affected by the fumigation treatment, still remains toxic.
