| [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 |

| terretonins e and f, inhibitors of the mitochondrial respiratory chain from the marine-derived fungus aspergillus insuetus (#). | two new meroterpenoids, terretonins e and f (1, 2), together with three known compounds, aurantiamine (3), linoleic acid, and uridine, were isolated as fermentation products of the marine-derived fungus aspergillus insuetus, which was associated with the sponge petrosia ficiformis. structures of all isolates were elucidated employing spectroscopic methods, mainly by two-dimensional nmr techniques. compounds 1-3 showed activity as inhibitors of the mammalian mitochondrial respiratory chain. | 2009 | 19719247 |
| novel terpenoids of the fungus aspergillus insuetus isolated from the mediterranean sponge psammocinia sp. collected along the coast of israel. | three novel meroterpenoids, insuetolides a-c (1-3) and four drimane sesquiterpenes, the new (e)-6-(4'-hydroxy-2'-butenoyl)-strobilactone a (4) and the known 2α, 9α, 11-trihydroxy-6-oxodrim-7-ene (5), strobilactone a (6) and (e,e)-6-(6',7'-dihydroxy-2',4'-octadienoyl)-strobilactone a (7), were isolated from the etoac extract of the culture medium of the marine-derived fungus aspergillus insuetus (oy-207), which was isolated from the mediterranean sponge psammocinia sp. the structures of the compo ... | 2011 | 21676619 |
| New taxa in Aspergillus section Usti. | Based on phylogenetic analysis of sequence data, Aspergillus section Usti includes 21 species, inclucing two teleomorphic species Aspergillus heterothallicus (= Emericella heterothallica) and Fennellia monodii. Aspergillus germanicus sp. nov. was isolated from indoor air in Germany. This species has identical ITS sequences with A. insuetusCBS 119.27, but is clearly distinct from that species based on ß-tubulin and calmodulin sequence data. This species is unable to grow at 37 °C, similarly to A. ... | 2011 | 21892244 |
| identification of ochratoxin a producing fungi associated with fresh and dry liquorice. | the presence of fungi on liquorice could contaminate the crop and result in elevated levels of mycotoxin. in this study, the mycobiota associated with fresh and dry liquorice was investigated in 3 producing regions of china. potential toxigenic fungi were tested for ochratoxin a (ota) and aflatoxin b1 (afb1) production using liquid chromatography/mass spectrometry/mass spectrometry. based on a polyphasic approach using morphological characters, β-tubulin and rna polymerase ii second largest subu ... | 2013 | 24205182 |
