1. Production of 5-ketogluconic acid using recombinant strains of Gluconobacter oxydans
University essay from Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)Abstract : 5-Keto-D-gluconic acid (5-KGA) is a valuable compound that has a wide range of applications in the chemical and food industries and is commonly used as a precursor for manufacturing tartaric acid (TA). Industrial production of 5-KGA through chemical approaches was practiced in the early 1920’s and was dropped immediately due to several drawbacks because of its complicated process that resulted in lower 5-KGA yield and higher accumulation of impure gluconic acid.

2. Evaluation of the stability of immobilized lipases from Rhizomucor miehei and Rhizopus oryzae in high oleic sunflower oil
University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)Abstract : Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. READ MORE

3. Unregulated Emissions from Heavy-Duty Engines and Vehicles
University essay from KTH/FordonsdynamikAbstract : Road transport emission levels are at an all-time low and post Euro VI regulations are now up for discussion. A literature study of unregulated diesel emissions in Europe; CO2, N2O, NO2, CH4 and aldehydes has been made to determine the effects and importance of the emissions in today´s heavy-duty vehicles.

4. Laminar Burning Velocity of Ethanol, Acetaldehyde and Ethanol-Acetaldehyde Flames
University essay from Lunds universitet/Fysiska institutionenAbstract : The objective of this study is to get new experimental data regarding to the burning velocities of ethanol, acetaldehyde and their mixture which has been performed by the heat flux method. It is known that the heat flux method for determination of laminar burning velocities is an efficient technique since the burning velocity can be determined directly, without applying extrapolations.

5. Impact of vehicle exhaust emitted by the combustion of biofuels on human health
University essay from Sektionen för ekonomi och teknik (SET)Abstract : Introduction: Significant changes in the global ecosystem, together with a potential shortfall in oil resources, have stimulated intense interest in the development of other sources of energy, and most particularly biofuels since these are basically considered to be less harmful to human health than petroleum-based fuels. However, information about the impact of biofuel-derived vehicle emissions on human health is limited and incomplete. READ MORE
