sources‚ such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren‚ 2003). Unlike diesel‚ biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren‚ 2003). Until today‚ it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2)‚ 20/80% (B20)‚ to 100% (B100) (Hafman‚ 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can

Abstract This experiment tested the hypothesis that the pure algae populations of Ankistrodesmus and Chorella will show growth in the number of organisms‚ and the mixed population will establish a dominant species. Each population should also reach its carrying capacity. All of the populations had the same resources available. The sampling of 0.5ml of each population was used to count the number of organisms. A Neubauer slide and microscope will be needed to do this. From this count‚

Jones Physical Science Honors 28 May 2014 Sentinels Under Attack Toxic algae blooms have infected many bodies of waters throughout the world and has greatly affected animals‚ humans‚ the environment‚ and even our economy. Toxic algae blooms can be detrimental to the environment and can singlehandedly turn a once healthy ecosystem into an inhabitable ‘dead zone’. Many marine mammals have been dying rapidly due to these toxic algae that poison the brain and lead to death that travels up through the food

Investigating the Control Dynamics of an Algae-Brine Shrimp Ecosystem 113437768 Introduction The purpose of this lab is to investigate whether an ecosystem consisting of marine algae and brine shrimp are controlled by top-down or bottom-up mechanisms. The terms top-down and bottom-up in the context of ecology describe which trophic levels are enforcing population pressures on the others. Thus‚ the top-down mechanism of control holds that consumers are responsible for determining the abundance of

Production of Biodiesel by Enzymatic Transesterification: using Waste Cooking Oil as feedstock and Candida Antarctica Lipase B as Biocatalyst. CHAPTER 1 INTRODUCTON The high cost of bio-diesel‚ compared to petroleum-based diesel‚ is a major barrier to its commercialization. It has been reported that 60-90% of bio-diesel cost arises from the cost of the feedstock oil (C.C. Lai et al.‚ 2005). Studies showed the potential of waste-cooking oil (WCO) as a material for biodiesel production (Sulaiman

lost a major advantage over petroleum. A promising alternative fuel source is biodiesel. Unlike ethanol‚ biodiesel can be used as a blend or pure biodiesel in standard diesel engines with little to no adaptations. It also burns a lot cleaner than petro diesel and can extend the life of the engine drastically. Procedure Biodiesel is very versatile and can be produced from many different things. In most cases biodiesel can be produced by transesterification of free fatty acids in which a catalyst
