  • An anacardic acid analog (1) was isolated from the fungus Paecilomyces variotii which was derived from the giant jellyfish Nemopilema nomurai. Compound 1 was isolated from a natural source for the first time and was evaluated for antibacterial activity against human and marine pathogens, including MDR (multidrugresistant) strains. Compound 1 exhibited mild antibacterial activity against Escherichia coli DC 2, Streptococcus iniae, and methicillin-resistant Staphylococcus aureus 3089 (MRSA).

  • We evaluated chemical, sensory and mechanical properties of breads containing different amount of Paecilomyces japonica powder to provide the basic informations for the development of functional bread. The pH of dough with 2% Paecilomices japonica powder was the highest but the pH of dough with 3% Paecilomices japonica powder was the lowest. Baking loss rate of bread added 3% Paecilomices japonica powder was the lowest but that of bread added 1% Paecilomyces japonica powder was the highest in that. The result of sensory evaluation showed that bread added 1% Paecilomices japonica Powder was significantly more preferable in chewiness, mouth feel, texture quality and overall quality. Sensory properties of softness, wheat flour odor, moisture, and mouth feel were positively correlated with the acceptability. Mechanical properties of hardness and chewiness had negative correlation with sensory properties, but springiness, gumminess and brittleness had positive correlation with those. The results of various measurements and evaluations showed that the quality of bread containing the Paecilomices japonica powder could be well accepted organoleptically. And this in turn proves the possibility of functional bread by use of Paecilomices japonica.

  • To estimate the inhibitory effect of some mushroom extract on melanin biosynthesis, we tested its inhibitory effects of five mushroom extracts on tyrosinase promoter in Bl6 mouse melanoma cells. In five mushroom extracts, Cordyceps militaris and Poria cocos exhibited low repression effect on tyrosinase promoter. However, Ganoderma lucidum, Paecilomyces japonicus, Phellinus linteus showed high repression effect, Especially, Paecilomyces japonicus and Phellinus linteus extracts had very higher repression effect approximately $81{\sim}83%\;at\;100{\mu}g/mL$. In the MTT assay, Paecilomyces japonicus and Phellinus linteus extracts exhibited high cytotoxicity. Therefore, repression effect of the extracts were closely connected with cytotoxicity.

  • Injection method of Paecilomyces japonica to Antheraea pernyi pupal body was investigated on feasibility for production of the corresponding vegetable wasp and plant worm. Infection rate of P. japonica to the pupae was 100%, and also fruiting body formation rate was 97%. The initial pupal body weight of 9.38 g befor injection of P. japonica to the pupae was finally reduced to 7.87g after two weeks in vivo culture. From these results, the injection method to pupal body will be useful for the production of Antheraea vegetable wasp and plant worm in future.

  • A biochemical characterization of the tannases from Paecilomyces variotii (produced at Unicamp), Aspergillus niger (purchased from Industrial Kerry Bio-Science) and A. niger cnpat 001 (purchased from Embrapa Agroindustrial Tropical-Brazil) was carried out. P variotii is a new strain obtained from the screening of 500 fungi that were tested for their production of tannase. The biochemical properties of this new tannase from P variotii were determined and compared with those of two other tannase preparations. The tannase produced from P. variotii showed optimum activity at pH 6.5. The functional temperature range of the tannases was from $20-70^{\circ}C$, with optima at $70^{\circ}C$ for P. variotii and at $60^{\circ}C$ for the commercially obtained tannase, whereas A. niger cnpat 001 showed optimum activity at $40^{\circ}C$. The effects of 1 mM preparations of cations and anions, inhibitors, surfactants, and chelators on the tannase activity from P. variotii were also studied.

  • Two new species of endophytic fungi were encountered during a diversity study of healthy tissues of chili pepper plants in Korea. The species were identified as Paecilomyces inflatus and Bionectria ochroleuca based on molecular and morphological analyses. Morphological descriptions of these endophytic isolates matched well with their molecular analysis. In the present study, detailed descriptions of internal transcribed spacer regions and morphological observations of these two fungi are presented.

  • The methanolic extract of fruiting body of Paecilomyces tenuipes DGUM 32001 showed significant cytotoxicity against human cancer cells: HepG2 and MCF-7. The methanolic extract was further fractionated with organic solvents such as chloroform and ethyl acetate in that order. Among the fractions tested, the ethyl acetate fraction showed the highest cytotoxicity against the carcinoma tested. The $IC_{50}$ values of ethyl acetate fraction against HepG and MCF-7 were 40 and 9.6 ${\mu}g/ml$, respectively.

  • A new indolinepeptide (3) was isolated, together with two known compounds, a cerebroside (1) and an alloxazine (2), from silkworm larvae infected with Paecilomyces sp. J300. On the basis of spectroscopic data, their structures were elucidated as (4E, 8E, 25, 2'R, 3R )-N-2'-hydroxy-hexadecanoyl-1-O-$\beta$-D-glucopyranosyl-9-methyl-4, 8-sphingadienine (1), 7,8-dimethylalloxazine (2) and 3$\beta$,5-dihydroxy-1-N-methyl-indoline-2$\beta$-carbonyl amino-D-alanyl-erythro-$\beta$-hydoxyiso-leucinyl-glycine (3).

  • During fungal diversity surveys of the order Eurotiales in Korea, two fungal strains, EML-DG33-1 and EML-NCP50, were isolated from samples of rat dung and fig tree leaf collected at a garden located in Gwangju in 2014. To complete the National Species List of Korea, it is a prerequisite to verify whether many questionable species, which were previously recorded but not confirmed, indeed present in Korea. Herein, the isolates were confirmed as undescribed species, Paecilomyces variotii and Talaromyces amestolkiae based on the combination of morphological and phylogenetic analyses of multigenes including the rDNA internal transcribed spacer, ${\beta}-tubulin$, and RNA polymerase II subunit 2.

  • Six entomopathogenic fungus isolates, Beauveria bassiana J57A, Nomuraea rileyi J125A, Paecilomyces farinosus J3A, Paecilomyces fumosoroseus J50A, Metarhizium anisopliae J88, Aspergilius sp. J64A, causing muscardine disease and aspergillosis in the silkworm, Bombyx mori were investigated for their cultural and morphological characteristics (on PDA culture media within 14 days at $24^{\circ}C$). The results showed that they differ each other from the features of cultural characteristics (colony elevation, colony color, colony growth rate) or morphological characteristics (conidiogenous cell structure, phialides, conidia size and shape). Among cultural characteristics, colony color is the easiest recognizable character between isolates. The morphological characteristics of each fungal isolate correspond to the descriptions of current system of classification.
