تجزیه بقایای گیاهی توسط قارچ¬های غیر بیمارگر گیاهی از اهداف این پژوهش بود. برای انجام آن کارپوفر قارچ¬های کلاهک¬دار صدفی و جنگلی چوب¬زی از روی تنه درختان افتاده و¬ کپک¬های سبز- زیتونی و سیاه از روی بقایای گیاهی جمع¬آوری و جدایه¬ها شناسایی شدند و شرایط محیطی مناسب رشد جدایه¬ها مورد مطالعه قرار گرفت. جهت بررسی روند تجزیه بقایای برنج، گندم، پنبه، کلزا و سویا با قارچ¬های مایه¬زنی شدند. سپس میزان هم...
A gram-negative bacillus, SMC-8986(T), which was isolated from the purulent exudate of an epidermal cyst but could not be identified by a conventional microbiologic method, was characterized by a variety of phenotypic and genotypic analyses. Sequences of the 16S rRNA gene revealed that this bacterium belongs to the genus Bordetella but diverged distinctly from previously described Bordetella sp...
Foraging in ants is generally organized along well-defined trails supporting a bi-directional flow of outbound and nestbound individuals and one can hypothesize that this flow is maximized to ensure a high rate of food return to the nest. In this paper we examine the effect of bottlenecks on the temporal organization of ant flow. In our experiments ants had to cross a bridge to go from their ne...
background: medicinal plants synthesize a vast array of secondary metabolites that are important for human life. for medicinal purpose, antimicrobial activity of substances derived from plant extracts has been recognized for many years. pimpinella anisum l. (apiaceae) and illicium verum hook. f. (illiciaceae) plant species, have been used for treatment of infectious diseases in iranian traditio...
We sought to determine if sufficient redundancy exists between specific IgE testing for Aspergillus fumigatus and Aspergillus niger to eliminate one of the assays in determining Aspergillus hypersensitivity. We reviewed regional laboratory results comparing A fumigatus-specific IgE with A niger-specific IgE using the Pharmacia UniCAP system (Pharmacia, Kalamazoo, MI). By using the Fisher exact ...
This paper is the second in a set of two investigating tilt-to-length (TTL) coupling. TTL describes cross-coupling angular or translational jitter into an interferometric phase signal and important noise source precision interferometers, including space gravitational wave detectors like LISA. We discussed 10.1088/2040-8986/ac675e coupling effects originating from optical path length changes, i....
The natural durability of wood to mold fungi was tested under laboratory conditions with locally sourced Citharexylum spinosum and Morus alba woods. The mold fungi were Penicillium selerotigenum, Paecilomyces variotii, and Aspergillus niger. Changes in surface elemental composition were evaluated with energy dispersive X-ray spectroscopy (EDX) and the biodeterioration of wood surfaces by scanni...
The effect of Aspergillus niger-fermented Terminalia catappa seed meal-based diet on the haematological parameters of broiler chicks was studied. T. catappa seed meal was inoculated with A. niger spore suspension and incubated at room temperature for 3 weeks. Forty-five, day-old broiler chicks with an initial average weight of 30.25 ± 2.40 g were divided into three groups of fifteen animals eac...
Sugar beet waste has potential value as a soil amendment and this work studied whether fermentation of the waste by Aspergillus niger would influence the growth and P uptake of arbuscular mycorrhizal (AM) fungi. Plants were grown in compartmentalised growth units, each with a root compartment (RC) and two lateral root-free compartments (RFC). One RFC contained untreated soil while the other RFC...
α-Galactosidase production by the fungal strains Penicillium chrysogenum LN33 and Aspergillus niger M47 cultivated in shaking and stationary conditions using soya meal extract as nutrient medium was investigated. Submerged shake flask fermentation was preferred over stationary cultivation for P. chrysogenum LN33 as it gave a high α-galactosidase yield (4200U/l). Because of pellet formation the ...
