Fig. 4From: Preservation stress resistance of melanin deficient conidia from Paecilomyces variotii and Penicillium roqueforti mutants generated via CRISPR/Cas9 genome editingUV-C radiation resistance of melanin deficient mutants from food spoilage fungi. Colours used correspond with the phenotype of the conidia, see Fig. 2. a The UV inactivation curves of A. niger N402 wild-type conidia (black lines) and A. niger MA93.1 melanin deficient mutant conidia (brown lines). A maximum of 3-log reduction in microbial load was observed in the mutant after UV treatment. b The UV inactivation curves of P. variotii CBS101075 wild-type conidia (light brown lines) and P. variotii PT32.5 melanin deficient mutant conidia (grey lines). A maximum of 7-log reduction in microbial load was observed in the mutant after UV treatment. c The UV inactivation curves of P. roqueforti LCP9604111 wild-type conidia (green lines) and P. roqueforti PT34.2 melanin deficient mutant conidia (grey lines). A maximum of 7-log reduction in microbial load was observed in the mutant after UV treatment. Three biological triplicates were measured. Inactivation curves were drawn based on linear regression modelBack to article page
