| mycosis in man due to arthrinium phaeospermum var. indicum. first case report. | arthrinium phaeospermum var. indicum kan & sullia was repeatedly isolated from erythematous nodules of a patient. scrapings of the experimental infection developed on rabbits revealed fungal filaments and few spores similar to those of a. phaeospermum var. indicum. the identity of the pathogen is discussed and it is being reported for the first time from human being. in vitro sensitivity of a. phaeospermum var. indicum to miconazole nitrate exhibited a minimum inhibition concentration of 6.25 mi ... | 1989 | 2608094 |
| effect of the raw extract of arthrinium strains (hyphomycetes, dematiaceae) on the growth of pathogenic bacteria in poultry feed. | poultry feed contains a significant reservoir of bacteria and is a possible source of salmonella typhimurium, staphylococcus aureus and escherichia coli, which can potentially infect farm animals and humans. the objective of this study was to determine whether the extract obtained from the culture of some arthrinium species was able to inhibit the growth of these bacteria. the results obtained showed that the raw extracts of arthrinium aureum, arthrinium serenensis and arthrinium phaeospermum in ... | 1999 | 10581733 |
| arthrichitin. a new cell wall active metabolite from arthrinium phaeospermum. | arthrichitin (1), c(33)h(46)n(4)o(9), is a new cell wall active depsipeptide isolated from the fermentation broth of arthrinium phaeospermum (hil y-903022). its structure was elucidated on the basis of spectroscopic and chemical degradation studies. arthrichitin consists of serine, beta-keto tryptophan, glutamic acid, and 2,4-dimethyl-3-hydroxydodecanoic acid units. | 1996 | 11667526 |
| in vitro conidial germination in arthrinium aureum and arthrinium phaeospermum. | this paper describes the microscopic details of conidial germination and the influence of ph, sodium chloride concentration, 3% glucose, 3% saccharose and ultraviolet irradiation on the conidial germination in arthrinium species. under laboratory conditions, germination started after an incubation period of 90 minutes in 2% malt extract broth at 25 degrees c. in vitro, the conidia of arthrinium species have a very low percentage of germination (a. phaeospermum: 7.9%; a. aureum: 15.8%). conidia o ... | 2004 | 15281397 |
| a new strain of arthrinium phaeospermum isolated from carex kobomugi ohwi is capable of gibberellin production. | plant growth-promoting endophytic fungi with gibberellin-producing ability were isolated from the roots of carex kobomugi ohwi, a common sand-dune plant, and bioassayed for plant growth-promotion. a new strain, arthrinium phaeospermum kacc43901, promoted growth of waito-c rice and atriplex gemelinii. analysis of its culture filtrate showed the presence of bioactive ga(1) (0.5 ng/ml), ga(3) (8.8 ng/ml), ga(4) (4.7 ng/ml) and ga(7) (2.2 ng/ml) along with physiologically inactive ga(5) (0.4 ng/ml), ... | 2009 | 18931975 |
| arthrinic acid, a novel antifungal polyhydroxyacid from arthrinium phaeospermum. | arthrinic acid was isolated from solid state fermentations of the fungus arthrinium phaeospermum. the structure of arthrinic acid was determined to be (6e,10e,14e,18e,20e)-2,3,5,9,13,17-hexahydroxy-20-(hydroxymethyl)-14,16,18,22,24-pentamethylhexacosa-6,10,14,18,20-pentaenoic acid from nmr spectroscopic studies. | 2008 | 18997391 |
| associations between fungal species and water damaged building materials. | fungal growth in damp or water damaged buildings worldwide is an increasing problem, which has adverse effects on both the occupants and the buildings. air sampling alone in moldy buildings does not reveal the full diversity of fungal species growing on building materials. one aim of this study was to estimate the qualitative and quantitative diversity of fungi growing on damp or water damaged building materials. another was to determine if associations exist between the most commonly found fung ... | 2011 | 21531835 |
| purification of protein ap-toxin from arthrinium phaeospermum causing blight in bambusa pervariabilis × dendrocalamopisis grandis and its metabolic effects on four bamboo varieties. | bambusa pervariabilis × dendrocalamopisis grandis blight is caused by a toxin produced by the fungus arthrinium phaeospermum. in this study, a toxin fraction (p1-2-2) with an estimated molecular mass of 31 kda was purified from a culture filtrate of this fungus by ammonium sulfate precipitation, sephadex g-50 gel chromatography, q sepharose fast flow anion exchange resin, and sephadex g-75 chromatography. the n-terminal amino acid sequence (i.e., h(2)n-gln-val-arg-asp-arg-leu-glu-ser-thr) determ ... | 2013 | 23095467 |
