THE EFFECTS OF CARBON AND NITROGEN SOURCES FOR THE GROWTH OF SOIL FUNGUS MPF- 7 AND ITS FERMENTATION OPTIMIZATION
Abstract
- In this research work, selected fungal strain collected from Mudon Township. The present study was focused on the utilization of carbon and nitrogen sources for the growth and fermentation conditions of soil fungus MPF-7 on Escherichia coli. In the growth effect of the carbon and nitrogen, the excellent growth of MPF-7 was found on glucose and peptone. In the study of fermentation conditions, MPF-7 showed the highest antibacterial activity (22.06 mm) by using 15% seed culture while the best inoculum age was found at 108 hrs on E. coli. In addition of glucose as the carbon source and peptone as nitrogen source in the fermentation, MPF-7 showed the highest antibacterial activity (21.05 mm) and (30.78 mm) on E. coli. Maximum antibacterial activity was observed at pH 6 (23.36 mm). In the temperature effect, the strong activity was obtained at 25ºC (23.18 mm). In the comparison effect of static and shaking culture of MPF-7, the maximum antibacterial metabolite was observed under shaking condition (20.00 mm) and the static culture of MPF-7 showed the activity (17.87 mm) on E. coli respectively.
