Sex in Penicillium series Roqueforti

Biocontrol of mold growth in high-moisture wheat stored under airtight conditions by Pichia anomala, Pichia guilliermondii, and Saccharomyces cerevisiae.

Pichia anomala inhibits the growth of Penicillium roqueforti and Aspergillus candidus on agar. In this investigation, antagonistic activity on agar against 17 mold species was determined. The abilities of Pichia anomala, Pichia guilliermondii, and Saccharomyces cerevisiae to inhibit the growth of the mold Penicillium roqueforti in nonsterile high-moisture wheat were compared by adding 10(3) Pen...

ATTACHMENT I--FINAL RISK ASSESSMENT PENICILLIUM ROQUEFORTI (February 1997) I. INTRODUCTION Penicillium roqueforti is a common saprophytic fungus, that is widespread in nature and can be isolated from soil, decaying

Molecular identification of species from the Penicillium roqueforti group associated with spoiled animal feed.

The Penicillium roqueforti group has recently been split into three species, P. roqueforti, Penicillium carneum, and Penicillium paneum, on the basis of differences in ribosomal DNA sequences and secondary metabolite profiles. We reevaluated the taxonomic identity of 52 livestock feed isolates from Sweden, previously identified by morphology as P. roqueforti, by comparing the sequences of the r...

Resolution of Penicillium roqueforti toxin and eremofortins A, B, and C by high-performance liquid chromatography.

A method for the quantitative analysis of Penicillium roqueforti toxin using a high-performance liquid chromatography system is proposed.

Induction of sexual reproduction and genetic diversity in the cheese fungus Penicillium roqueforti

The emblematic fungus Penicillium roqueforti is used throughout the world as a starter culture in the production of blue-veined cheeses. Like other industrial filamentous fungi, P. roqueforti was thought to lack a sexual cycle. However, an ability to induce recombination is of great economic and fundamental importance, as it would make it possible to transform and improve industrial strains, pr...
