Bread could last 60 days without molding

Micro ZAP has developed a technique using a special microwave device to keep bread mold-free for up to two months. Normally, bread goes moldy in about 10 days, but with Micro ZAP's method, mold spores are killed in about 10 seconds, extending the bread's freshness to 60 days.

Under normal conditions, how long does it take for bread to go moldy?

What is the main purpose of the special microwave device used by Micro ZAP?
