Milk is a great blessing of nature. It is a complete food from the few months baby to the elder person. It provides the entire elements needed by a body for its development and growth such as protein‚ water‚ carbohydrates‚ minerals‚ fat and vitamins. It not only provides power but also enhances immunity to fight against many different types of pathogens. It is necessary for the growth of bones and for the blood clotting. It fulfills body’s calcium requirement. 100g of cow’s milk contains 3.9g fat

Determination of citrinin produced by P. notatum and A. nigerin liquid media The filtrates obtained from above experiment were used for extraction and estimation of citrinin. Briefly‚ the citrinin was extracted thrice with chloroform (1:1 v/v). All the three extractions were pooled and concentrated in vacuum at 40°C using a rotary evaporator. The crude extract was then diluted in minimum amount of chloroform (2ml) and citrinin was estimated by thin layer chromatography (TLC) according to Razak et

WTHESIS STATEMENT: “BIOCONVERSION OF WATER HYACINTH (EICHHORNIA CRASSIPES) TO ETHANOL.” 1. INTRODUCTION Water hyacinth (Eichhornia crassipes) is a free-floating or rooted in mud plant or weed which can totally cover fresh water lakes‚ harbors‚ and other essentially relatively occluded fresh water bodies. It is a fast growing permanent aquatic plant that are extensively scattered all throughout the world. This tropical plant can be the reason for the infestation over large areas of water resources

ABSTRACT Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of

Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are
