INTRODUCTION The excessive consumption of fossil fuels‚ particularly in large urban areas‚ has greatly contributed to generation of high levels of pollution. There is a need for environmentally sustainable energy sources to find a viable and long-term substitute for liquid petroleum. As a step to solve this problem‚ the use or addition of biofuels to gasoline‚ which reduces emission of carbon monoxide and unburned hydrocarbons that form smog‚ has widely been enforced in recent years (Wyman

life. Yeast cells‚ such as Saccharomyces cerevisiae‚ have the ability to sense and adapt to nutrient levels in their external and internal environment. This ability to sense and adapt to nutrient levels play an essential role in their survival‚ such as to regulate many physiological processes like‚ metabolism‚ cell development‚ cell proliferation‚ protein synthesis‚ translation‚ and cell death; autophagy. One main sensor for nutrient sensing in Saccharomyces cerevisiae is the target of rapamycin

report #1 The uptake of neutral red dye in a yeast cell using different solutions Abstract Every cell transports materials in and out throught something called a membrane. There are many different methods of transport in the cell Saccharomyces cerevisiae (Serrano‚ 1977) We want to know does adding higher concentrations of azide more effectively block dye transport? We tested the transport of dye in yeast cells with a metabolic inhibitor. When we did this we showed no difference in the absorbance

converted to compounds which give the bread its taste as it is baked in the oven. What Is Yeast? Yeasts consist of only one cell and belong to the kingdom of Fungi. There are an estimated 1‚500 species of yeast with the common yeast being Saccharomyces cerevisiae‚ used for making bread and also beer. Yeasts need sugar to grow. They divide in a process called budding. When was this Process discovered? Extensive research shows that Ancient Egypt was the birthplace of the bread we know today

MICROBES AND FOOD – A ‘RELATIONSHIP’ Microbes and food have always had a love-hate relationship. Food producers have learned to harness their power -- and sometimes for good use. There is no doubt that organically grown fruits and vegetables are superior in flavor. Now‚ despite arguments to the contrary made by food manufacturers‚ they may well be more nutritious for a variety of reasons. There are always studies available to prove any point‚ especially one

Dragon fruit‚ also known as pitaya or pitahaya‚ belongs to the Hylocereus genus of the Cactaceae family. It is recognized as leathery‚ slightly leafy – skinned sweet fruit of many cactus species rooted from Mexico‚ which was believed to be then brought to Central America by the European. Nowadays‚ dragon fruits are widely cultivated in the United States‚ the South East Asia region‚ Israel‚ Australia‚ Cyprus‚ as well as the Canary Islands (Morton‚ 1987). The term “dragon fruit” is used in English
