Abstract
The genus Eurotimn was found to be most sensitive to the medium containing potassium sorbate alone or in combination with salmine sulfate. The tested agents were also found effective for inhibiting the growth of Botryotina fukelina, Epicoccum purpurascens and Aspergillus conicus. The synergistic effect upon the growth inhibition of molds was greater than sorbate alone when the concentration of the mixture of salmine and sorbate was raised from 500 to 1000μg per ml medium. Combined effect of the mixture of 0.05% salmine sulfate plus 0.05% sorbate exerted inhibitory effect on the growth of mold species. The combination of 0.08-0.09% salmine sulfateplus 0.02-0.01% sorbate were found suitable for inhibiting a number of molds. The pH greatlyinfluenced the survivability of spores in presence of both the preservatives. However, the com-bination of 0.08% salmine sulfate plus 0.02% sorbate exerted lethal effect on the survivability ofconidial spores in a wide pH range.
