Seven strains of Penicillium viridicatum isolated from country-cured ham produced citrinin in potato dextrose broth and on country-cured ham. None of the strains produced detectable amounts of citrinin at 10 C. The optimal temperature range for citrinin production was 25 to 30 C.

The paper provides the results of the microbiological analysis of samples taken from the mummified remains of St. Marcian. Microorganisms found belong to bacteria and fungi of the genera Aspergillus, Bacillus, Penicillium, Sarcina, and Shewanella which are all apart of the common air, soil, and human microbial flora and therefore present no health hazard.

Various fungi were isolated during the course of a survey in a cold-store of apples in the Netherlands. One of these fungi belongs to the genus Penicillium and produces cleistothecia at 9 and 15 °C. A detailed study using a combination of phenotypic characters, sequences and extrolite patterns showed that these isolates belong to a new species within the series Roqueforti. The formation of clei...

Penifulvins B-E (2-5), four new sesquiterpenoids with a dioxa[5.5.5.6]fenestrane ring system, have been isolated from cultures of an isolate of Penicillium griseofulvum (NRRL 35584), together with a new silphinene derivative, 12-hydroxysilphinene-15-oic acid (6). Penifulvins B-E (2-5) are oxidized analogues of penifulvin A (1) and were identified by analysis of NMR and MS data. 12-Hydroxysilphi...

A rapid technique is described for propagation, harvest, and purification of gram quantities of conidia of five Aspergillus and six Penicillium species.

Penicillium menonorum is described as a new monoverticillate, non-vesiculate species that resembles P. restrictum and P. pimiteouiense. On the basis of phylogenetic analysis of DNA sequences from four loci, P. menonorum occurs in a clade with P. pimiteouiense, P. vinaceum, P. guttulosum, P. rubidurum, and P. parvum. Genealogical concordance analysis was applied to P. pimiteouiense and P. parvum...

Two new fungal metabolites, penicipyrone (1), and penicilactone (2), were isolated from the marine-derived fungus Penicillium sp. PSU-F44 along with three known macrolides, (+)-brefeldin A (3), (+)-brefeldin C (4), and 7-oxobrefeldin A (5). Their antimicrobial activities against methicillin-resistant Staphylococcus aureus SK1 and Microsporum gypseum SH-MU-4 were examined.

Tomatoes are soft skin fruits highly susceptible to fungi contamination, mainly through injured skin or damaged tissues (AYRES; KRAFT; PIERCE, 1964; PEARSON; HALL, 1975). Strains from several fungi species are known to produce toxins on tomatoes during field production or storage. In the U.S.A., the main fungi genera found in tomatoes were Alternaria, Aspergillus, Botrytis, Cladosporium, Collet...
