ISSN: 1573-0832Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract In two field sowings, the effect of five pesticides on soil, rhizosphere and rhizoplane fungi was tested. Ceresan and Orthocid (fungicides used as seed dressing) after 3 days were very toxic to the total count of soil fungi and to almost all fungal genera and species. After 40 days their toxicity was almost alleviated in the soil, but persisted in the rhizosphere. The herbicide VCS 438 did not significantly affect the total count of soil fungi but was initiative to the total rhizosphere fungi. Some fungal species were significantly promoted in the soil and rhizosphere and others were depressed. Dipterex (Insecticide) was promotive to the total count of soil fungi after 3 days and to some fungal species but this effect was almost alleviated after 40 days. In the rhizosphere, it exerted a promotive effect on the total count of fungi and on some fungal genera and species. Dursban (Insecticide) was of no significant effect on the total count of soil and rhizosphere fungi, but few species were significantly promoted. The rhizoplane fungi were the least sensitive, and none of the five pesticides induced a significant effect on the total count, but some species responded significantly, being either promoted or inhibited.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-0832Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract The fungi of 40 samples of barley grains collected from Upper Egypt were estimated using the dilution- and the grain-plate methods. 33 genera and 109 species, in addition to 2 varieties of Aspergillus nidulans, one variety of Aspergillus flavus and one variety of Penicillium cyclopium were identified. The spectrum of fungal genera and species collected by the grain-plate method (29 genera and 94 species+3 varieties) was broader than by the dilutionplate method (27 genera and 71 species+3 varieties), but the order of frequency of occurrence of fungal genera and species was basically similar in the two methods. The most frequent genera were Aspergillus (25 species+3 varieties), Penicillium (32 species+1 variety), Rhizopus (2 species), Alternaria (2 species), Fusarium (6 species) and Drechslera (5 species) and were represented (as assayed by the grainplate method) in 100 %, 77.5 %, 85 % 62,5 %, 60 % and 52.5 % of the samples constituting 60.4 %, 10.2 %, 7.7 %, 3.7 %, 5 % and 2.3 % of the gross total count of fungi respectively. From the preceding genera A. niger, A. fumigatus, A. flavus, A. sydowii, P. notatum, P. citrinum, F. oxysporum, F. moniliforme, F. solani, R. stolonifer, A. alternata and D. spicifera were the most frequent.Type of Medium: Electronic ResourceURL: -

ISSN: 1420-9071Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Résumé L'étude d'un précurseur probable dans la production de l'acide nicotinique par leMycobacterium tuberculosis hominis, révéla que les acides aminiques hétérocycliques, qui sont indispensables à plusieurs organismes, comme le tryptophan et l'histidine, sont bactériostatiques à l'organisme. Cet organisme se développait dans une solution synthétique de Proskauer & Beck (Vorwald's modification). Les acides aminiques tels que l'ornithine et l'arginine aidèrent à sa croissance et favorisèrent la production d'acide nicotinique, ressemblant sur ce point à l'asparagine. Des études préliminaires faites sur des cobayes infectés par l'organisme tuberculeux confirmèrent l'effet bactériostatique du tryptophanein vitro. Du tryptophane fut administré, de façon sous-cutanée, à raison de 125 mg par jour pour 10 jours consécutifs, immédiatement après l'infection, à un groupe d'animaux. Un second groupe subit le même traitement, mais à deux semaines du jour de l'infection. Un troisième groupe fut infecté, mais laissé sans traitement. Tous ces animaux furent observés pendant 9 semaines. Après examen bactériologique, microscopipue et macroscopique, l'effet bactériostatique du tryptophanein vivo put être démontré.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-482XSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract We report here on the electrical properties (resistance, dielectric constant and pyroelectric current behaviour), magnetic susceptibilityX M and differential thermal analysis (DTA) for the polycrystalline powdered samples of sodium tartrate dihydrate (STD), Na2C4H4O6·2H2O. These mentioned properties are used as a probe for the detection and the studying of the different transitions that have been found in this salt. It has been observed that the various results (electric, magnetic and thermal) strongly support each other and confirm the actual presence of the phase transformations in this compound.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1573-482XSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyMechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The relative permittivity (ɛ) and the electrical resistivity (ϱ) were measured at varying temperature from 310 up to 490 K for polycrystalline samples of ammonium hydrogen tartrate (AHT), NH4HC4H4O6. The measured parameters revealed that the compound undergoes successive solid-state structural phase transitions at ~ 368 K, 428 K and ~ 473 K, in addition to a probable change in the conduction mechanism at ~ 333 K. A differential thermal analysis (DTA) thermogram and a thermogravimetric analysis (TGA) plot were also performed from room temperature (~ 300 K) up to the melting point. The DTA results strongly support the existence of the above-mentioned solid-state phase transitions, whereas the TGA plot indicates the absence of any actual loss in weight in the transition temperature regions. The data are correlated to the reorientational motion of the NH4 + ion, combined with the arrangement of the molecules in their crystals and in particular the hydrogen bonding system.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2932Source: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringNotes: Abstract The side effects of fluazifop-butyl on soil fungal populations and oxygen uptake were studied by incubating soil samples with a range of fluazifop-butyl concentrations (0, 0.6, 3 and 6 μg g−1) over 8 weeks. Cellulose decomposition in soil was also studied in laboratory experiments with the herbicide which was either incorporated in soil or sprayed onto calico squares which were buried in soil. The mycelial dry weight of six fungal species under the effect of the herbicide was also examined. Fluazifop-butyl had no significant effect on total fungal propagule populations at 0.6 μg g−1. At 3 and 6 μg g−1, it caused temporary reduction in fungal populations observed after 1 and 2-wk of incubation. The herbicide had no significant effect on OZ uptake. The decay of calico buried in herbicide-treated soil was generally stimulated, while the decomposition of herbicide-treated calico, buried in untreated soil, was temporary delayed. The mycelial dry weight yields of Aspergillus favus (at 2 and 12 μg mL−1 of fluazifop-butyl) and Cunninghamella echinulata (at 12 μg mL−1) were significantly increased. At 24 μg mL−1 the mycelial dry weight of A. flavus and Alternaria alternata was significantly reduced.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-0832Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract Bladex (Cyanazine), when applied to the soil was poisonous to the counts of total fungi and of Aspergillus, 20 days after treatment with the low dose and 40 days after treatment with the low and the medium doses. This effect was alleviated after 80 days. In the agar medium, Bladex promoted the counts of total fungi, Aspergillus, A. terreus and A. flavus. In liquid medium, it exerted no significant effect on the growth of all test fungi. Gesaprim-Combi (Atrazine) depressed the total count of fungi, 2 and 5 days after treatment with the 3 doses. This toxic effect was completely alleviated after 40 and 80 days. In the agar medium, it significantly promoted the total count of fungi by the 3 doses used. The mycelium growth, of Alternaria alternata, Trichoderma viride, Myrothecium verrucaria, Cunninghamella echinulata, Gliocladium roseum and Penicillium verruculosum was significantly suppressed.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-0832Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract 100 species and 2 varieties of A. nidulans which belong to 35 genera were identified from 40 samples of barley collected from different places in Upper Egypt. Two methods of isolation were used: the grain-and the dilution plate. The spectrum of fungal genera and species collected by the former (35 genera, 96 species+1 variety) was broader than by the latter method (28 genera, 76 species+1 variety). Nine genera were of high occurrence (represented in more than 50% of the samples) namely, Aspergillus, Penicillium, Fusarium, Alternaria, Chaetomium, Cladosporium, Humicola, Drechslera and Myrothecium. The most frequent species were A. fumigatus, A. niger, A. flavus, A. sydowii, F. oxysporum, F. moniliforme, A. alternata, M. verrucaria, P. funiculosum, P. corylophilum, P. duclauxi, C. herbarum, C. globosum, D. spicifera and H. grisea. Several fungi such as Chaetomium, Humicola, Altemaria, Drechslera, Stachybotrys, Myrothecium, Pénicillium corylophilum and P. funiculosum were far more frequently recovered on cellulose than on glucose agar.Type of Medium: Electronic ResourceURL:
