The feedstock used in our experiment for the production of biodiesel was Yellow Grease. The whole experiment was divided into two parts: Production and Testing. Production involves Transesterification of free fatty acids in yellow grease to form yellow grease alkyl esters. The process of testing involved calculation of the physio – chemical properties, acid value, density, kinematics viscosity ...

Five non-toxin producing cyanobacterial isolates from the genera Synechococcus, Trichormus, Microcystis, Leptolyngbya and Chlorogloea were examined in terms of quantity and quality as lipid feedstock for biofuel production. Under the conditions used in this study, the biomass productivity ranged from 3.7 to 52.7 mg·L-1·day-1 in relation to dry biomass, while the lipid productivity varied betwee...

Physicochemical properties of the commercially procured rubber seed oil (RSO) were studied to evaluate its potential as viable feedstock for biodiesel production. The procured rubber seed oil were characterized for acid value, saponification value, free fatty acid, flash point, kinematic viscosity, and refractive indices using standard methods. Results indicate that the procured rubber seed oil...

Here we report the 3.7-Mb draft genome sequence of Acetobacter tropicalis NBRC16470(T), which can produce optically pure d-glyceric acid (d-GA; 99% enantiomeric excess) from raw glycerol feedstock derived from biodiesel fuel production processes.

Microalgae have been receiving worldwide attention as promising feedstock for production of carbon neutral biodiesel. As an alternative fuel, biodiesel is very imperative for the sustainable development of mankind. Biodiesel production process is generally carried out through upstream and downstream processing to generate cellular biomass, extracted oil and finally transesterification reaction....

Growing concern regarding energy resources and the environment has increased interest in the study of alternative sources of energy. To meet increasing energy requirements, there has been growing interest in alternative fuels like biodiesel to provide a suitable diesel oil substitute for internal combustion engines. Biodiesels offer a very promising alternative to diesel oil since they are rene...

Biodiesel derived from renewable plant sources is monoalkyl esters of long chain fatty acids which fall in the carbon range C12-C22. It has similar properties as mineral diesel. Various processes exist to convert vegetable oils (mainly triglycerides) into biodiesel. Transesterification of vegetable oils using alcohol in a catalytic environment is most commonly used method for producing biodiese...

The utilization of bioethanol as the alcohol source for biodiesel production is more environmentally advantageous over methanol owing to its lower toxicity, lower flammability and its sustainable supply from renewable agricultural resources. However, as the presence of water in crude bioethanol is the critical factor limiting the biodiesel production process, the energy-intensive and costly pur...

In this research, the energy flow and production energy indices of canola cultivation in Trakya province of Turkey, Golestan and Mazandaran provinces of Iran were compared. Diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. The results indicated that despite the higher energy use of machinery in Trakya province of T...

A significant problem associated with the commercial acceptance of biodiesel is poor oxidative stability. This study investigates the effectiveness of various natural and synthetic antioxidants [a-tocopherol (a-T), butylated hydroxyanisole (BHA), butyl-4-methylphenol (BHT), tert-butylhydroquinone (TBHQ), 2, 5-di-tert-butylhydroquinone (DTBHQ), ionol BF200 (IB), propylgallate (PG), and pyrogallo...
