Bismuth-inhibitory effects on bacteria and stimulation of fungal growth in vitro

الملخص EN

Bismuth salicylate was found to inhibit the growth of a range of bacteria and yeast, ‘‘Candida albicans’’.

In general the growth of bacteria did not result in increase in bismuth solubilisation, in contrast, bismuth solubilisation increased following the growth of C.

albicans.

A significant increase in the biomass (dry weight) of Aspergillus niger and Aspergillus oryzae occurred in vitro when these fungi were grown in the presence of bismuth salicylate.

Biomass increase occurred over a range of bismuth compound additions, which in the case of A.

oryzae was associated with increase in the solubilisation of the insoluble bismuth compounds
