Penicillium roqueforti has been used for centuries in the production of Roquefort cheese, giving it its distinctive flavor. However, this fungus can also be a potent food spoiler. Its spores can be relatively heat resistant , allowing them to survive heat treatment.
We sequenced the genome of Penicillium roqueforti strain LCP96 04111 in an effort to gain more insight into the mechanism of heat resistance.
