When Penicillium brevicompactum is grown on Czapek Dox medium in the surface or sub merged mode as batch or continuous-flow cultures, mycophenolic acid is produced. Unlike the classical secondary metabolic system, 6-methylsalicylic acid production by P. patulum, mycophenolic acid is formed independently of dilution rate in a flow system. Discounting the possibility that strains of P. brevicompactum that produce mycophenolic acid are mutants defective in the control of secondary metabolite biosynthesis, we conclude that mycophenolic acid production is not regulated as part of a non-vegetative genome. An invertase (EC 3.2.1.26) activity has been encountered in both P. brevicompactum and P. patulum.

Penicillium brevicompactum is a filamentous ascomycete used in the pharmaceutical industry to produce mycophenolic acid, an immunosuppressant agent. To extend options for genetic engineering of this fungus, we have tested two resistance markers that have not previously been applied to P. brevicompactum. Although a generally available phleomycin resistance marker (ble) was successfully used in DNA-mediated transformation experiments, we were not able to use a commonly applicable nourseothricin resistance cassette (nat1). To circumvent this failure, we constructed a new nat gene, considering the codon bias for P. brevicompactum. We then used this modified nat gene in subsequent transformation experiments for the targeted disruption of two nuclear genes, MAT1-2-1 and flbA. For MAT1-2-1, we obtained deletion strains with a frequency of about 10%. In the case of flbA, the frequency was about 4%, and this disruption strain also showed reduced conidiospore formation. To confirm the deletion, we used ble to reintroduce the wild-type genes. This step restored the wild-type phenotype in the flbA deletion strain, which had a sporulation defect. The successful transformation system described here substantially extends options for genetically manipulating the biotechnologically relevant fungus P. brevicompactum.

Twenty naturally infected ginger (Zingiber officinale) rhizomes displaying visible mold growth were examined to identify the fungi and to evaluate the presence of fungal secondary metabolites. Penicillium brevicompactum was the predominant species isolated from 85% of the samples. Mycophenolic acid was identified from corresponding tissue extracts. Because mycophenolic acid is a potent immunosuppressant and synergistic mycotoxicosis studies involving human consumption have not been carried out on this metabolite, spoilage of commercially marketed produce caused by P. brevicompactum is a concern. This is the first reported occurrence of mycophenolic acid in commercially sold plant food products.

Penicillium brevicompactum produces mycophenolic acid as it grows vegetatively, not only on a simple medium where growth is slow but also on a richer medium where growth is less restricted. The implications of this finding on the association of fungal secondary metabolism with the idiophase in liquid and solid culture are discussed.
