| Abstract | ||
| This study have been done to know the sensivity of the fungus Penicillium digitatum (Pers.:Fr) Sacc.toward some bicarbonat salts ( NaHCO3 , KHCO3 and NH4HCO3 ) at various concentration ranged between( 0.0 – 100.0)mM . The result indicates that the three salts give clear effect to inhibit fungal colonies growth. There were a reversiabl relationship between the salts (bicarbonate) concentration and the means of redial growth of colony. 10.0mM was gave the minimum growth inhibition while 50.0mM gave the maximum growth inhibition. There were a reversiabl relationship between pH and the mean of redial growth.The minimum growth inhibition was at pH = 7.0 while maximum growth inhibition was at pH = 10.0.There were a clear effect on colony diameter when there were an interaction occure between pH and salts concentration , at 0.0mM concentration ,the minimum growth inhibition was at pH = 6.0 while maximum growth inhibition was at pH = 8.5 . , at 5.0mM concentration ,the minimum growth inhibition was at pH = 4.5 while maximum growth inhibition was at pH = 8.5 , at 25.0mM concentration ,the minimum growth inhibition was at pH = 4.5 while maximum growth inhibition was at pH = 8.5 , and at 50.0mM concentration ,the minimum growth inhibition was at pH = 4.5 while maximum growth inhibition was at pH = 8.5 . | ||
