The method is demonstrated using mercury-resistant and mercury-susceptible isolates of Penicillium expansum and Cladosporium cladosporioides. With P. expansum no consistent differences in uptake were recorded. Mercury-resistant isolates of C. cladosporioides consistently absorbed less CMNP into their hyphae than did mercury-susceptible isolates. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-107-1-31
