Penicillium genome project

Penicillium, one of the largest and most ubiquitous fungal genera, currently contains more than 500 accepted species occurring worldwide in a diverse range of habitats, from soil to vegetation, air, indoor environments, and various food products [1]. The best known species is P. chrysogenum, the producer of the renowned antibiotic penicillin, which famously revolutionized medical approaches to treating bacterial diseases. Penicillium species play important and varied roles, such as the production of special cheeses by P. camemberti [2] and P. roqueforti [3], and fermentation of sausages by P. nalgiovense and P. salamii [4]. Other species can have adverse effects: allergies in humans, devastating rots on food crops by pre- and post-harvest pathogens, and food contamination by mycotoxins [5].

Most relevant for this project, Penicillium genomes encode enzymes [6-7] that are active on plant biomass (CAZymes) and biosynthetic pathways whose novel enzymes may be utilized for production of biofuels and bioproducts.
