Recent Patents on Biotechnology, 2012
Penicillium species are a widespread source of biologically active compounds and enzymes which are exploited in biotechnologies. The ongoing discovery of new species, their biochemical and molecular characterization, and the application of the new findings in diverse industrial processes stimulate an increasing interest of patentees worldwide.

Transformation in Penicillium chrysogenum
Gene, 1987An auxotrophic mutant of Penicillium chrysogenum with a DNA rearrangement that affects the trpC region has been transformed to the Trp+ phenotype by using a plasmid that contains the trifunctional wild-type gene. A frequency of 40-80 transformants per microgram of input DNA was usually achieved.

Conidiation induction in Penicillium
Research in Microbiology, 2003Asexual spores or conidia are dispersive propagules produced as an alternative to vegetative growth by a diverse group of filamentous fungi. The cellular development programmes which govern conidiation have been intensely studied in the last few decades, although important gaps stand in the way of our understanding of this phenomenon, namely in the ...

Acidification of apple and orange hosts by Penicillium digitatum and Penicillium expansum
International Journal of Food Microbiology, 2014New information about virulence mechanisms of Penicillium digitatum and Penicillium expansum could be an important avenue to control fungal diseases. In this study, the ability of P. digitatum and P. expansum to enhance their virulence by locally modulating the pH of oranges and apples was evaluated. For each host, pH changes with a compatible pathogen

International audience ; Penicillium roqueforti is used as a fungal adjunct culture for the production of blue-veined cheeses worldwide. The physiological traits of this fungus explain its adaptation to the cheese matrix and thus its ability to develop in the cheese-making environment.

Conidium Ontogeny in Penicillium
Journal of General Microbiology, 1971After fixation with permanganate or with glutaraldehyde and osmium tetroxide, phialide walls of Penicillium clavigerum Damelius, P. claviforme Bainier and P. corymbiferum Westling were electron-transparent with a thin, electron-opaque surface layer. The phialide apex was closed by a hollow, plug-like structure of wall material.

As taxonomic characters in Penicillium, morphology and profiles of secondary metabolites have proved to be consistent and reproducible, provided they are recorded in a standardized and systematic way. Techniques for standardising profiles of secondary metabolites include the use of griseofulvin and preferably other commercially available secondary ...

A new species ofPenicillium belonging to theP.funiculosum series of the Biverticillata — Symmetrica section is described from the rhizosphere ofBrassica campestris var.toria. The species is characterized by the presence of penicilli with 8–12 metulae on malt-extract agar and a very limited sporulation on Czapek-Dox agar. The species is namedPenicillium
