The detection of these antagonistic substances revealed interesting properties that justify its importance and its study on the potential application in biological control of pathogenic microorganisms and spoilage food. For these reasons, the biochemical nature and the best conditions to production of the substances studied in this work are being investigated to further purification experiments. Many microorganisms have been evaluated for the production of antimicrobial substance. However the high cost and low yields have been the main problem for its industrial production 25 .
In 2004 my mother was dying of lung cancer (never smoked), and she told me she never had flu or colds. I realized that was true; she was never sick when we were growing up in the 50’s & 60’s. So I decided that, as her daughter, I didn’t have to be sick either. I realized I was choosing to be sick so that I could stop – I just needed a break in life. But being sick meant I couldn’t enjoy any of the activities I told myself were available to me if I could just skip going to work. I haven’t been sick since.
