Potassium sorbate was found to inhibit germination and growth of a range of spoilage fungi isolated from tobacco below pH 5. However, at and above pH 5 the efficacy of potassium sorbate was influenced by substrate composition and water activity ( a w ). Eurotium spp., Aspergillus flavus, A. fumigatus, A. niger , and Penicillium species all grew with 0·1–0·3% sorbate at 0·95 a w on ma Virginia and Burley extract agars. However, at 0·85 a w , only Eurotium spp., A. flavus, P. chrysogenum and P… CONTINUE READING
