| [hydrolysis of streptococcal polysaccharides by micromycete dextranases]. | the effect of dextranase enzyme preparations obtained from penicillium piscarium bim g-102, penicillium funiculosum, aspergillus insuetus g-116 and aspergillus ustus on polysaccharides synthesized by cariesogenic streptococcus sanguis and streptococcus mitis was being studied. according to the data obtained dextranases from p. piscarium, p. funiculosum and asp. ustus can be considered as a promising anticarious agent. | 1984 | 6540443 |
| production of the tremorgenic mycotoxins verruculogen and fumitremorgin b by penicillium piscarium westling. | the tremorgenic mycotoxins verruculogen and fumitremorgin b were isolated from penicillium piscarium westling. the coexistence of these tremorgens in culture has previously been reported for one other unrelated fungal species, aspergillus caespitosus raper and thom, and lends further support to the suggestion that the tremorgens have a common biosynthetic origin. | 1977 | 16345234 |
| [diketopiperazine alkaloids from the fungus penicillium piscarium westling]. | fungi of the species penicillium piscarium produced diketopiperazine alkaloids (isorugulosuvine, puberuline, verrucosine, prolyltryptophanyldiketopiperazine, 12,13-dehydroprolyltryptophanyldiketopiperazine, fellutanine a, phenylalanylphenylalanyldiketopiperazine, as well as roquefortine and 3,12-dihydroroquefortine whose precursors are tryptophan, phenylalanine, leucine, proline, and histidine. | 2007 | 10867952 |
| [effect of various factors on the biosynthesis of piscarinines, secondary metabolites of the fungus penicillium piscarium westling]. | piscarinines a and b were synthesized most actively during the surface cultivation of the fungus penicillium piscarium in a complex medium (5.5 mg/l). under conditions of submerged cultivation in a mineral medium, the yield of piscarinines was two times lower. an increase in the inoculum quantity of conidia treated with tween-80 increased the culture productivity. the biosynthesis of the alkaloid was completely suppressed when mannitol was replaced with glucose or when zinc, iron, or copper ions ... | 2016 | 19145974 |
| [rugulosuvines a and b--diketopiperazine alkaloids from penicillium rugulosum and penicillium piscarium fungi]. | two diketopiperazine alkaloids, rugulosuvines a and b (tryptophan and phenylalanine are precursors), were isolated and purified from the culture liquid of penicillium rugulosum vkm f-352 and penicillium piscarium vkm f-325 fungi. physical and physicochemical studies showed the absolute structure of rugulosuvine a. the absolute structure of rugulosuvine b was demonstrated to be similar to that of rugulosuvine a. | 2001 | 11443897 |
| penicillium svalbardense, a new species from arctic glacial ice. | during investigations of mycobiota in the coastal arctic polythermal glaciers, different species of the ubiquitous genus penicillium were isolated from the extreme subglacial environment. a group of penicillium strains was obtained that did not belong to any known penicillium species. this species was isolated in high numbers from the kongsvegen subglacial ice and was not detected in the surrounding environment. a detailed analysis of secondary metabolite profiles, physiological and morphologica ... | 2007 | 17252316 |
