Contamination of Stored Pistachios to Aspergillus Section Flavi and Aflatoxins
Background: Contamination of stored pistachio nuts to Aspergillus section Flavi and aflatoxins (AFs) as well as effective parameters on fungal growth and AF production during storage was assayed. Methods: Twenty one pistachio nut samples were taken from some warehouse of Damghan county. Different parameters of storage, including temperature, relative humidity, and pest infestation were recorded...
متن کاملEffect of UV-B radiation on photosynthetic pigments and UV-absorbing compounds of three different soybean cultivars (Glycine max L.).
The effects of UV-B radiation on the amount of chlorophyll a, b, carotenoids, flavonoids, anthocyanins, and polyphenols of three soybean cultivars was studied. After germination in the incubator, plants were put in pots of soil and during 3 weeks and irrigated with Hoagland solution every day. After 3 weeks, plants were exposed to UV-B for 20 min every day for a week. In each cultivar, UV-B red...
متن کاملStructural diversity of Aspergillus (section nigri) spores.
The taxonomy of fungal species, similar to that of many other microorganisms, suffers frequent revisions due to the discovery of new species and to the development and gathering of characterization data and morphological information. Morpho-taxonomy helps in the identification of many species. This work presents the macro, micro-morphological, and spectral mass analyses for phenotypic character...
متن کاملPARTIAL PURIFICATION AND CHARACTERIZATION OF B-GALACTOSIDASE FROM ASPERGILLUS NIGER UV-5
The enzyme pgalactosidase from a mutant strain of A. niger UV-5 was partially purified using ammonium sulfate and acetone. The saturation range of 60-80% ammonium sulfate was found to yield 60.5% enzyme recovery with 2.4 fold purification. Acetone precipitation at enzyme: acetone ratio of 1 : 1.5 brought about a higher yield i.e. 68% and three-fold purification. The combined procedures of ...
متن کامل[Melanoma, altitude, and UV-B radiation].
BACKGROUND AND OBJECTIVES UV radiation is the main modifiable risk factor for the development of cutaneous melanoma. Many people in the Spanish province of Granada live at high altitudes and, therefore, receive high doses of UV-B radiation. The aims of this study were to assess the possible association between melanoma and altitude and to measure the daily erythemal dose at different altitudes....
