The use of solid and liquid medium to study the effects of heavy metals on the growth of Candida albicans

Abstract EN

Sabouraud's dextrose (solid and liquid) medium has been used to examine the response of Candida albicans to Cobalt , Nickel , Silver , Copper and Lead in three doses per each (10 , 25 and 50) mg/l in different exposure periods .

In the solid medium the number of colonies was not effected by all metals ions , except Ag ions'(25 and 50) mg/l which completely inhibited the colonies numbers .

In the liquid medium the effect of these metals on the growth was in the following sequence Co , Ni .

Ag , Cu and Pb respectively: ' Most elements studied: showed increase in- the ‘inhibition effect on the growth with A increasing the ions concentration in the medium , whilethe inhibition effect decreased with the increasing periods of exposure
