Forty eight soil samples were collected from 12 garbage waste soils of Ranchi, Jharkhand and screened for presence of keratinophilic fungi using hair baiting techniques for isolation. Fungal growths appearing on the baits after two to four weeks of incubation at room temperature were microscopically examined and cultured on mycological media. Cultures were then identified on the basis of coloni...
An extracellular ribonuclease from Rhizopus stolonifer (designated as RNase Rs) was purified to homogeneity by chromatography on DEAE-cellulose followed by CM-cellulose. The Mr of the purified enzyme determined by gel filtration and SDS-PAGE is 25,000 and 28,200, respectively. RNase Rs is a glycoprotein and contains 10.5% neutral sugar. It is an acidic protein with a pI of 5.0 and has a blocked...
Beef luncheon meat is one of the most popular meals in several countries in the world including Egypt. Thirty one fungal species and 3 species varieties were recovered from 30 samples of beef luncheon meat collected from different supermarkets in Qena. Alternaria, Aspergillus, Emericella, Mucor, Mycosphaerella, Penicillium and Rhizopus were the most common genera on the two types of media. From...
UV radiation is effective on all microbial forms in water but lethal doses for every particular taxonomic group may be considerably different. Three species of Penicillium, Aspergillus and Cladosporium genera, 2 species of Alternaria and Fusarium and 1 species of Rhizopus and Paecilomyces genera were tested. Model waters were inoculated with spores of the mentioned monocultures. Three heterocul...
there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...
Background: In biomedical research, silver nanoparticles have attracted the attention of many scientists in drug delivery and other applications. This study investigates characterization biologically synthesized their efficacy on cancer cells. Methods: The produced was accomplished using UV:visible absorption spectroscopy, which showed maximum at 422 nm. structural morphology carried out by tra...
ریشههای چغندرقند به همراه خاک چسبیده به آن پساز برداشت جهت فرآوری به کارخانههای قند حملشده و در اولین مرحله توسط فشار آب شستشو میشوند. آب گلآلود حاصلاز شستشوی ریشهها بهعنوان پساب کارخانه توسط کانال به مزارع منطقه انتقال یافته و جهت آبیاری مورد استفاده قرار میگیرد. با توجه به امکان انتقال عوامل بیماریزا توسط خاک و آب، طی سال 1384یک بار در هفته در زمان فعالیت کارخانهقند بردسیر از پسا...
