| the isolation of phoma eupyrena from a human lesion. | a strain of the soil-borne fungus phoma eupyrena was isolated from the skin of an 18-month-old boy who had a crusting, erythematous, perioral eruption of one month's duration. treatment with clotrimazole, 15% zinc oxide paste, and dimethicone resulted in eradication of the fungus and in complete healing of the lesions in eight weeks. | 1981 | 7247430 |
| hydroxylation of the herbicide isoproturon by fungi isolated from agricultural soil. | several asco-, basidio-, and zygomycetes isolated from an agricultural field were shown to be able to hydroxylate the phenylurea herbicide isoproturon [n-(4-isopropylphenyl)-n',n'-dimethylurea] to n-(4-(2-hydroxy-1-methylethyl)phenyl)-n',n'-dimethylurea and n-(4-(1-hydroxy-1-methylethyl)phenyl)-n',n'-dimethylurea. bacterial metabolism of isoproturon has previously been shown to proceed by an initial demethylation to n-(4-isopropylphenyl)-n'-methylurea. in soils, however, hydroxylated metabolites ... | 2005 | 16332769 |
| potato carrot agar with manganese as an isolation medium for alternaria, epicoccum and phoma. | a semi-selective medium for isolation of alternaria spp., epicoccum sp. and phoma spp. from soil and plant samples was developed. the basal medium was a modified potato carrot agar (pca), containing 10 g/l of potato and carrot. it is known that the target genera sporulate well on standard pca when grown at 25 degrees c with an alternating light/dark cycle consisting of 8 h of cool-white daylight followed by 16 h darkness. addition of 1.5% mncl(2) 4 h(2)o (w/v) inhibited most other fungi than alt ... | 2009 | 19185378 |
| autochthonous ascomycetes in depollution of polychlorinated biphenyls contaminated soil and sediment. | we investigated the capacity of a consortium of ascomycetous strains, doratomyces nanus, doratomyces purpureofuscus, doratomyces verrucisporus, myceliophthora thermophila, phoma eupyrena and thermoascus crustaceus in the mycoremediation of historically contaminated soil and sediment by polychlorinated biphenyls (pcbs). analyses of 15 pcb concentrations in three mesocosms containing soil from which the fungal strains had previously been isolated, revealed significant pcb depletions of 16.9% for t ... | 2014 | 24880600 |
| potential of autochthonous fungal strains isolated from contaminated soils for degradation of polychlorinated biphenyls. | up to now, most studies on polychlorinated biphenyl (pcb) bioremediation have examined the ability of model fungal strains to biodegrade pcbs. yet, there is limited information concerning the potential of autochthonous filamentous fungal strains in the biodegradation of pcbs and their possible use in the environmental technologies. in this study, we investigated the capacity of autochthonous fungal strains in the biodegradation of pcbs by isolating 24 taxa from former industrial sites highly con ... | 2013 | 23622721 |
| detection and identification of phoma pathogens of potato. | phoma foveata, phoma exigua var. exigua, and phoma eupyrena are fungal pathogens of potato, causing gangrene or pit rot symptoms in tubers, and they are responsible for significant crop losses. various techniques are available to identify these pathogens in the laboratory. a multiplex plexor(®) real-time pcr method which can detect and identify these pathogens in a single reaction will be presented. | 2015 | 25981243 |
| microbial degradation of the thiolcarbamate herbicide, diallate, in soils and by pure cultures of soil microorganisms. | the disappearance of the herbicide, avadex (40% diallate), from five agricultural soils (differing in either ph, carbon content, or nitrogen content), incubated under sterile and non-sterile conditions, was followed for a period of 20 weeks. avadex was rapidly lost from microbiologically active soils, with over 50% of the applied (2.5 ppm) dosage disappearing within four weeks; losses from sterile soils were much slower with recoveries of over 50% after 20 weeks. incubation of soil with avadex t ... | 1976 | 1267481 |
