| growth of chitinolytic dune soil beta-subclass proteobacteria in response to invading fungal hyphae. | it has frequently been reported that chitinolytic soil bacteria, in particular biocontrol strains, can lyse living fungal hyphae, thereby releasing potential growth substrate. however, the conditions used in such assays (high bacterial density, rich media, fragmented hyphae) make it difficult to determine whether mycolytic activity is actually of importance for the growth and survival of chitinolytic bacteria in soils. an unidentified group of beta-subclass proteobacteria (cbetaps) was most domi ... | 2001 | 11472904 |
| do stable isotopes reflect the food web development in regenerating ecosystems? | we evaluated the use of delta15n- and delta13c-values to monitor the development of food web complexity and biodiversity in a regenerating ecosystem. therefore a model food chain was established feeding cultivated woodlice (porcellio dilatatus) on a cellulolytic fungus (chaetomium globosum) grown on cellulose paper. two diets of different quality (c:n ratios of 54 vs. 200) with different delta15n- (1.3% vs. 3.1%) but identical delta13c-values caused low and high dietary stress in animals of trea ... | 2000 | 11501706 |

| phytotoxic chaetoglobosins are produced by the plant pathogen calonectria morganii (anamorph cylindrocladium scoparium). | by the application of a bioassay based on cresson seedlings, two phytotoxic compounds were isolated by thin-layer chromatography from the culture fluid of a calonectria morganii isolate. the structure of both compounds was elucidated by esi/ms and nmr spectroscopy. according to the chemical abstracts database, they were identified as chaetoglobosin a and 19-o-acetylchaetoglobosin a, mycotoxins originally described for chaetomium globosum. | 2001 | 12483566 |
| use of gas chromatography-mass spectrometry/solid phase microextraction for the identification of mvocs from moldy building materials. | gas chromatography-mass spectrometry/solid phase microextraction (gc-ms/spme) was applied to identify microbial volatile organic compounds (mvocs) in water-damaged, mold-infested building materials (gypsum board papers (n=2), mineral wool, and masonite) and in cultivated molds (aspergillus penicillioides, stachybotrys chartarum, and chaetomium globosum). three spme fibers (65-microm pdms-dvb, 75-microm carboxen-pdms, and 70-microm carbowax-stableflex) designed for automated injection were used o ... | 2003 | 12531501 |
| survival of filamentous fungi in hypersaline dead sea water. | a variety of filamentous fungi have recently been isolated from the dead sea (340 g/l total dissolved salts). to assess the extent to which such fungi can survive for prolonged periods in dead sea water, we examined the survival of both spores and mycelia in undiluted dead sea water and in dead sea water diluted to different degrees with distilled water. mycelia of aspergillus versicolor and chaetomium globosum strains isolated from the dead sea remained viable for up to 8 weeks in undiluted dea ... | 2003 | 12545316 |
| microbial community composition affects soil fungistasis. | most soils inhibit fungal germination and growth to a certain extent, a phenomenon known as soil fungistasis. previous observations have implicated microorganisms as the causal agents of fungistasis, with their action mediated either by available carbon limitation (nutrient deprivation hypothesis) or production of antifungal compounds (antibiosis hypothesis). to obtain evidence for either of these hypotheses, we measured soil respiration and microbial numbers (as indicators of nutrient stress) a ... | 2003 | 12571002 |
| detection of viable fungal spores contaminant on documents and rapid control of the effectiveness of an ethylene oxide disinfection using atp assay. | filamentous fungi are able to damage and even destroy archival and library materials. nowadays the conventional method for detecting such micro-organisms is to put them in cultures but such methods are laborious and time-consuming. atp methodology has been widely applied in other domains and its success on bacteria and yeast has been demonstrated. several commercial reagent kits are available but they did not give satisfactory results on spores mould. we have elaborated new extraction strategies ... | 2003 | 12687632 |

| in vitro activities of new antifungal agents against chaetomium spp. and inoculum standardization. | chaetomium is an unusual etiological agent of human infections, but the mortality rate among immunocompromised patients is considerably greater than that among nonimmunocompromised individuals. we investigated the in vitro antifungal susceptibilities to novel antifungal agents of 19 strains belonging to three species of chaetomium which have been involved in human infections, i.e., chaetomium globosum, c. atrobrunneum, and c. nigricolor, and one strain of the closely related species achaetomium ... | 2003 | 14506025 |
| infection of barley roots by chaetomium globosum: evidence for a protective role of the exodermis. | plant pathogenesis by fungi is known to be dependent on the host genotype, the virulence of the pathogen and certain environmental conditions influencing fungal establishment. previously, it has been shown that chaetomium globosum, a fungus well-characterized for its biocontrol potential, causes necrosis on barley roots grown in murashige and skoog (ms)-agar. using ms-agar and aeroponic culture as axenic plant growth systems, c. globosum pathogenesis was analyzed with serological and histologica ... | 2003 | 14563137 |
