Three Penicillium species have been isolated from insect specimens in Korea; Penicillium sp., P. steckii, and P. polonicum. Penicillium sp. (KNU12-3-2) was isolated from Lixus imperessiventris, while P. polonicum (KNU12-1-8) and Penicillium steckii (KNU12-2-9) were isolated from Muljarus japonicas and Meloe proscarabaeus, respectively. The identification was based on the morphological character...

A total of 106 Penicillium species were tested to examine their ability of degrading cellobiose, pectin and xylan. The activity of β-glucosidase was generally strong in all the Penicillium species tested. P. citrinum, P. charlesii, P. manginii and P. aurantiacum showed the higher ability of producing β-glucosidase than other tested species. Pectinase activity was detected in 24 Penicillium spec...

A homeomorphism f : X → X of a compactum X is expansive (resp. continuum-wise expansive) if there is c > 0 such that if x, y ∈ X and x 6= y (resp. if A is a nondegenerate subcontinuum of X), then there is n ∈ Z such that d(f(x), f(y)) > c (resp. diam f(A) > c). We prove the following theorem: If f is a continuum-wise expansive homeomorphism of a compactum X and the covering dimension of X is po...

We describe three new fungicolous species on the basis of phenotypic and phylogenetic differences from known species. Penicillium thiersii, P. angulare and Penicillium decaturense are described. Penicillium thiersii phenotypically is identified on the basis of several characteristics including growth rates, vesicle size and condium shape and roughening. Penicillium angulare is related most clos...

BACKGROUND The genus Penicillium contains a large number of ubiquitous environmental taxa, of which some species are clinically important. Identification of Penicillium down to the species level is currently based on polyphasic criteria, including phenotypic features and genetic markers. Biodiversity of the genus Penicillium from Mazandaran and Tehran provinces has not been described. OBJECTI...

the aim of this study was identification of fungi in indoor and outdoor of asthmatic patients´ home environment. opened plates (containing of malt extract agar media) were used for isolation of fungi in the air of indoor (n=360) and outdoor (n=180) of 90 asthmatic patients̉ home living in the city of sari at the level of breathing height. plates were incubated in room temperature for 7-14 days. ...

It is shown that a barycentrically soft compactum is necessarily an absolute retract of weight ≤ ω1. Since softness of a map is the mapping version of the property of a space to be an absolute retract, the above mentioned result can be considered as mapping version of the Ditor–Haydon Theorem stating that if P (X) is an absolute retract then the compactum X is of weight ≤ ω1 [2]. All spaces con...

The aim of this research was the analysis of the possible antagonistic effect of Penicillium oxalicum over the pathogen rice fungus A. alternata under different conditions of temperature, water activity and culture media. The macroscopic study of the dual growth revealed that according to the Index of Dominance P. oxalicum was more competitive that A. alternata at 25°C whereas at 15°C was this ...
