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

Toxicity of terpenes to spores and mycelium of Penicillium digitatum
Biotechnology and Bioengineering, 2002AbstractSpores, although often considered metabolically inert, catalyze a variety of reactions. The use of spores instead of mycelium for bioconversions has several advantages. In this paper, we describe the difference in susceptibility of mycelium and spores against toxic substrates and products.

Synchronized sporulation in Penicillium digitatum (Sacc.)
Canadian Journal of Microbiology, 1972Biochemical studies of the sporulation process in mycelial fungi require a thallus in which the conidiation (production of conidiophores and conidia) will take place in a synchronous manner.A method was worked out which permits an approximate evaluation of 5 degrees of the synchronous sporulation of Penicillium digitatum. A suitable nutritional regime

Geraniol biotransformation-pathway in spores of Penicillium digitatum
Applied Microbiology and Biotechnology, 2001Spores of Penicillium digitatum ATCC 201167 transform geraniol, nerol, citral, and geranic acid into methylheptenone. Spore extracts of P. digitatum convert geraniol and nerol NAD+-dependently into citral. Spore extract also converts citral NAD+-dependently into geranic acid.

THE BIOSYNTHESIS OF SOME AMINO ACIDS IN PENICILLIUM DIGITATUM
Canadian Journal of Microbiology, 1958The pathways of biosynthesis of alanine, serine, glycine, aspartic acid, and glutamic acid in Penicillium digitntum have been studied by means of tracer techniques, using glucose-2-C14and glucose-6-C11as carbon sources. Alanine appears to be derived directly from pyruvate formed in the glycolytic degradation of glucose.

International Journal of Food Microbiology, 1988
In vitro and in vivo tests were carried out to study the inhibitory effect of mixtures of sodium orthophenylphenate, methyl-1-(butyl-carbamoyl)-2-benzimidazole ('Benomyl') and sodium orthophenylphenate, 2-(4-thiazolil)-benzimidazole ('Thiabendazole') on growth of strains of Penicillium italicum and P.

Phytochemistry, 1970
Abstract The production and purification of pectin transeliminase of Penicillium italicum is described and certain properties of this enzyme are compared with the pectin transeliminase of P. digitatum . Evidence is presented for the production of pectin transeliminase in vivo in oranges rotted by these fungi.

Fungicidal Actions and Resistance Mechanisms of Prochloraz to Penicillium digitatum
Plant Disease, 2021The demethylation inhibitor (DMI) fungicide prochloraz has been widely used in China to control citrus green mold, which is caused by Penicillium digitatum. The 50% effective concentration (EC50) values of prochloraz for 129 isolates of P. digitatum collected in 2017 from citrus groves of four provinces of China ranged from 0.0032 to 0.4582 mg/liter ...

Biotransformation of testosterone and progesterone by Penicillium digitatum MRC 500787
Collection of Czechoslovak Chemical Communications, 2010The biotransformation of testosterone and progesterone byPenicillium digitatumMRC 500787 for 5 days is described. The biotransformation of testosterone afforded 5α-androstane-3,17-dione, 3α-hydroxy-5α-androstan-17-one, 3β-hydroxy-5α-androstan-17-one and androst-4-ene-3,17-dione. The biotransformation of progesterone afforded 5α-pregnane-3,20-dione.

The Production of Ethylene by Penicillium Digitatum
Mycologia, 1954P. digitatum does not require any specific nitrogen source to produce ethylene. If organic and inorganic nitrogen compounds allowed growth, ethylene was produced.
