Tutor: Date: A biofuel is made from a biological process known as carbon fixation. These biofuels are gotten from the conversion of biomass, solid biomass, liquid fuels as well as biogases. The biofuels are continued to be known because of the high prices of fossil fuels and also for the purposes of ensuring fuel security in various countries. (Caye, D. & Terry W.2008). The biofuels are produced from two distinct ways; that is through metabolic by-products or from living organisms. Examples of

aspect to development SUMMARY In a world of rapid growth, both in terms of economy and population, human beings have sought to influence the environment around them for a better, more efficient and easier life. The resources that we have used up from the environment have often been nonrenewable and in our heedless march to glorious comfort, we have ignored the consequences of the effect that we are having on the world we live in. With the results of our negative impact on nature coming around

will only come from fundamental innovations in science and technology. Liquid fuels will for some applications be necessary for an indefinite period of time. Therefore, defining relevant feedstocks, producing fuels from these feedstocks and the properties of these fuels are critical issues. The utilization of biomass resources assumes importance due to the soaring crude price and depleting reserves of fossil fuels coupled with the rising environmental concern. Ethanol derived from renewable ligno-cellulosic

transportation fuels, and the demand has been steadily rising. Provisional estimates have indicated crude oil consumption in 2007-08 at about 156 million tonnes. The domestic crude oil is able to meet only about 23% of the demand, while the rest is met from imported crude.

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural energy services. Based on REN21's 2014 report, renewables contributed 19 percent to our global energy consumption and 22 percent to our electricity generation in

ABSTRACT Food and feed is possibly the area where processing anchored in biological agents has the deepest roots. Despite this, process improvement or design and implementation of novel approaches has been consistently performed, and more so in recent years, where significant advances in enzyme engineering has fastened the place of such developments. Targeted improvements aim at enzymes with enhanced thermal and operational stability, improved specific activity, modification of pH-activity profiles
