The use of moulds as a seasoning for sausage can have both desirable and undesirable consequences. The desirable consequences are the creation of a successful product that appeals to consumers. The undesirable consequences are due to the growth of undesirable moulds that produce highly toxic secondary metabolites referred to as mycotoxins. The aim of the paper was to investigate the presence of...

MPA (mycophenolic acid) is an immunosuppressive drug produced by several fungi in Penicillium subgenus Penicillium. This toxic metabolite is an inhibitor of IMPDH (IMP dehydrogenase). The MPA-biosynthetic cluster of Penicillium brevicompactum contains a gene encoding a B-type IMPDH, IMPDH-B, which confers MPA resistance. Surprisingly, all members of the subgenus Penicillium contain genes encodi...

During study on biodiversity of Penicillium and Talaromyces species occurring on grape berries and raisin in vineyards of East- & West Azarbaijan and Gazvin provinces of Iran, five species of Penicillium and Talaromyces, namely, Penicillium crocicola, P. olsonii, P. sumatrense, Talaromyces atroroseus and T. minioluteus were characterized based on combination of morphological data and β-tubulin ...

We studied the biodegradation of compounds containing phosphorus-to-carbon bonds by using a wild-type strain of Penicillium notatum. The substrate specificity of this strain was studied, and we found that it is able to utilize structurally diverse organophosphonates as sole sources of phosphorus. This ability seems to be inducible, as indicated by the presence of a lag phase during growth. A po...

In a preliminary communication (Ghosh, 1959) it was reported that fresh and wet mycelium of Penicillium chrysogenum, as obtained from a rotary filter in a penicillin plant, could be well utilized as the sole source of nitrogen for penicillin production by the mold either in shaken flask or in aerated and agitated large fermentors. The waste mycelium did not need any pretreatment whatsoever and ...

The title meroterpene neoaustin {systematic name: (1'S,2'R,3S,7'R,9'S,11'S,12'R)-11'-hydr-oxy-2,2,2',9',12'-penta-methyl-6',15'-dimethyl-ene-2,6-dihydro-13'-oxaspiro-[pyran-3,5'-tetra-cyclo-[7.5.1.0(1,11).0(2,7)]penta-deca-ne]-6,10',14'-trione}, C(25)H(30)O(6), comprises five rings, three six-membered and two five-membered. The absolute configuration was established based on [α(D)] = +166.91° (...

A study was made of Penicillium chrysogenum and some other fungi to determine the relative distribution of intra- and extracellular invertase produced by them in submerged fermentation. The proportion of each type of enzyme varied with the organism and the period of fermentation. More of the enzyme initially bound to the mycelium was released into the medium with the progress of fermentation. D...

Conidia of Penicillium chrysogenum and Penicillium frequentans and sporangiospores of Rhizopus rhizopodiformis, Rhizomucor pusillus, and Mucor racemosus were subjected to partition in aqueous polymer two-phase systems. The partition behavior differed drastically between the conidia of the two Penicillium species and the sporangiospores of the three species of phycomycetes. This difference in pa...
