Purpose: To evaluate the anticonvulsant, antimicrobial and cytotoxic activities of Berberis calliobotrys. Methods: The powdered plant material (10 kg) was extracted thrice with methanol (3 × 12 L) by dipping for seven days. The methanol extract was concentrated to dryness under reduced pressure, and then successively fractionated with solvents of different polarity, including n-hexane, chlorofo...

In the present investigation, the compound responsible for antioxidant, antimicrobial and anti-inflammatory properties in methanolic extract of leaves of Murraya koenigii L. was determined by PerkinElmer GC Claurus 500 system and Gas Chromatograph interfaced to a Mass Spectrometer GC/MS technique. GC-MS analysis of methanol extract of the leaves of the plant revealed the existence of 1Methyl-py...

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 ...

PENICILLIN WAS discovered by Alexander Fleming in September 1928 while he was a member of the staff of the Inoculation Department (now the Wright Fleming Institute) at St. Mary's Hospital, London, and had just been appointed Professor of Bacteriology in the University of London. He had noticed an unusual phenomenon, absence of fully developed colonies of a common microbe, Staphylococcus aureus,...

Several enzymes with lysophospholipase/phospholipase B activity have been described from the budding yeast Saccharomyces cerevisiae. In vitro, these enzymes are capable of hydrolyzing all phospholipids that can be extracted from yeast cells. Two forms of the enzyme have been isolated from plasma membranes and a third from culture supernatants and the periplasmic space, but their biological role...

BACKGROUND: Beauveria bassiana is an important entomopathogenic fungus currently under development as a bio-control agent for a variety of insect pests. Although reported to be non-toxic to vertebrates, the potential allergenicity of Beauveria species has not been widely studied. METHODS: IgE-reactivity studies were performed using sera from patients displaying mould hypersensitivity by immunob...

Penicillium chrysogenum is a ubiquitous airborne fungus detected in every sampled region of the Earth. Owing to its role in Alexander Fleming's serendipitous discovery of Penicillin in 1928, the fungus has generated widespread scientific interest; however its natural history is not well understood. Research has demonstrated speciation within P. chrysogenum, describing the existence of four cryp...

Penicillium species are rarely reported agents of infections in immunocompromised patients. We report 3 cases of invasive mycosis caused by voriconazole-resistant Penicillium oxalicum in patients with acute myeloid leukemia, diabetes mellitus, and chronic obstructive pulmonary disease, while on voriconazole therapy. Penicillium oxalicum has not been previously recognized as a cause of invasive ...

The genus Penicillium phylogenetically belongs to Trichocomaceae, with approximately 300 reported species. The majority of these species are saprobic and commonly occur in soil. This paper reports the genome sequence of Penicillium capsulatum strain ATCC 48735, a rare Penicillium species used in paper manufactories and that was recently reported as a human-invasive opportunist.

Upon studying the diversity of fungal endophytes associated with pine trees in Korea, many species of Penicillium were encountered. In this study, we report two species of Penicillium isolated from the needles of Pinus rigida. Based on ID region analysis, cultural and morphological characteristics, the two species were identified as Penicillium fellutanum and P. toxicarium, both of which are ne...
