Title: Influence of bioactive chemicals isolated from soil fungi on human earwax bacteria
Abstract: To culture fungi that maybe produce antibiotics the soil samples were collected from many areas in Basra; Al-seeba, Al-saraji and Nahar-khooz. Fungal growth was in the Potato Dextrose Agar, the duration of the fungi lasted from 6-8 days and many types of fungi had grown in the medium: Chaetomium spp, Penicillium notatum and Penicillium. Bacteria samples were collected from the earwax of the students. Bacterial growth wad in the Nutrient agar, the duration of the bacteria lasted from 3-5 days. After that, the fungi and the bacteria were put together in the same dishes of nutrient agar for inhibitory action. To see how bioactive chemicals of fungi effects on bacteria in the zone of inhibition. The actions of inhibition within that zone, are often of varying kinds and degrees of permanence. However, a variation in the inhibitory action, based on the inhibition zones diameter, among the examined fungus was noticed. Basra soil fungi have proven to be rich sources of novel natural compounds with a wide spectrum of biological activities. This study revealed that this soil fungus showed a significant antibacterial activity.
