| [penicillium ulaiense hsieh, su & tzean, a post-harvest pathogen of citrus fruits in northeastern argentina]. | fungi were isolated from the surface of decaying citrus fruits and their pathogenicity was determined. a few rotten fruits presented coremia of penicillium ulaiense hsieh, su & tzean, a new postharvest pathogen in latin america. penicillium digitatum (89 strains). penicillium italicum (28). p. ulaiense (12) and geotrichum candidum (11) were isolated from 129 samples of citrus fruits. | 1995 | 8552758 |
| biotransformations of 6',7'-dihydroxybergamottin and 6',7'-epoxybergamottin by the citrus-pathogenic fungi diminish cytochrome p450 3a4 inhibitory activity. | penicillium digitatum, as well as five other citrus pathogenic species, (penicillium ulaiense link, geotrichum citri link, botrytis cinerea p. micheli ex pers., lasiodiplodia theobromae (pat.) griffon & maubl., and phomopsis citri (teleomorph diaporthe citri)) were observed to convert 6',7'-epoxybergamottin (1) into 6',7'-dihydroxybergamottin (2), bergaptol (3), and an opened lactone ring metabolite 6,7-furano-5-(6',7'-dihydroxy geranyloxy)-2-hydroxy-hydrocoumaric acid (4). metabolism of 2 by th ... | 2012 | 22342630 |
| exocellular hydrolases from penicillium ulaiense. | penicillium ulaiense exhibited carboxymethylcellulase, pectinase, protease, amylase and phenolase activities, while no xylanase, cellulase, lipase or ligninase activities were found. pectinolytic action was studied in liquid medium, showing low levels of pectinesterase and pectinase production. no mycotoxins were detected by thin-layer-chromatography. | 1996 | 24415322 |
