The aim of this experimental study was to isolate and partially purify extracellular protease from Penicillium janthinellum and Neurospora crassa.The species were inoculated in a protease fermentation medium .The supernatants were collected after 92 hours. The partial purification was realized by applying respectively, ammonium sulfate precipitation,(More)
Antioxidant property of Phomopsis amygdali culture filtrate extracted with ethanol, was evaluated in vitro. ABTS and DPPH radicals were used to evaluate their antioxidant activity. Antioxidant components like total phenol and flavonoid were also determined. The ethanolic extract of Phomopsis amygdali showed potent antioxidant activity against both ABTS and(More)
Wine, an alcoholic beverage is prepared by different fruit juices with appropriate processing and additions (Amerine and Singleton, 1968). The conventional process of wine making involves the fermentation of grape juice. However, there are numerous reports available on wine preparation from other fruits such as apple, plum, apricot, pomegranate, strawberry,(More)
The antifungal activity of five different medicinal plants namely Lawsonia inermis L, Mimosa pudica L, Phyllanthus niruri L., Tephrosia purpurea Pens., Vinca rosea L. were tested against plant pathogenic fungi Pythium debaryanum (causing damping off of disease) by agar well diffusion method. The plant leaves were extracted with various solvents like(More)
It is well known that non-small cell lung cancer (NSCLC) is a heterogeneous group of diseases. Previous studies have demonstrated genetic variation among different ethnic groups in the epidermal growth factor receptor (EGFR) in NSCLC. Research by our group and others has recently shown a lower frequency of EGFR mutations in African Americans with NSCLC, as(More)
Chitosan is a derivative of chitin, the second most abundant natural polymer on earth after cellulose. It is the major component of skeletal or exoskeletal structure of lower animals, particularly crustacea, molluscs and insects. It is also present in a vast majority of fungi as the principle fibrillar polymer of the cell wall. Fungal cell walls and septa(More)
In this study, the bioactive compounds of Enicostemma littorale have been evaluated using GCMS. The chemical compositions of the whole plant methanol extract of Enicostemma littorale were investigated using Perkin-Elmer Gas chromatography-mass spectrometry. The mass spectra of the compounds, found in the extract was matched with characterization and(More)
The synthesis of designer solid-state materials by living organisms is an emerging field in bio-nanotechnology. Key examples include the use of engineered viruses as templates for cobalt oxide (Co(3)O(4)) particles, superparamagnetic cobalt-platinum alloy nanowires and gold-cobalt oxide nanowires for photovoltaic and battery-related applications. Here, we(More)
