A two-stage culture strategy was used for maximum biomass production under nutrient-sufficient conditions, followed by cultivation under low-salt stress, to cause the accumulation of oil in the biomass. Controlled conditions of nitrate, salt concentration, and time to exposure to stress were...

Disposal of wastewater often results in high nutrient loading into aquatic environments, which may lead to favorable conditions for undesirable phytoplankton blooms. Microalgae are efficient in removing nitrogen, phosphorus, and toxic metals from wastewater under controlled environments. If key...

Deoxygenation of microalgal oil obtained by pyrolysis of microalgae was carried out for the production of hydrocarbon fuel from biomass by metal supported catalyst. Oleic acid was used as a model reactant to select an optimized catalyst. Effects of support, metal species, and metal loading on...

We propose an integration of drying with gasification and combined cycle-based power generation for microalgae. This system is based on enhanced process integration, which includes two core technologies: exergy recovery and process integration. Exergy recovery is achieved by exergy elevation and...

An experimental study has been carried to use raw Algae oil and its methyl esters in an indirect injection diesel engine. Effects of engine speed, engine load output, injection timing of the algae biofuel and engine compression ratio on the engine output torque, combustion noise (maximum...

To enhance energy production efficiency (EPE) from microalgae Chlorella pyrenoidosa (CP), cassava starch (CS) was mixed with CP to optimise the carbon/nitrogen (C/N) ratio and facilitate efficient dark hydrogen fermentation, followed by photo hydrogen fermentation and methanogenesis. Steam...

CO<SUB align="right"><SMALL>2</SMALL></SUB> emission, which is feared to bring more harm than benefit to the environment, can be prevented and reduced through the cultivation of microalgae. Microalga is the fastest growing organism (estimated 40 times faster than terrestrial grass) and requires a high CO<SUB align="right"><SMALL>2</SMALL></SUB> concentration to reproduce....</small></sub></small></sub>

Microalgae productivity in tubular photobioreactors depends on algae species, location, tube diameter, biomass concentration, distance between tubes and for vertically stacked systems, the number of horizontal tubes per stack. A simulation model for horizontal and vertically stacked horizontal...

Climate change and rising atmospheric CO2 levels have become much debated environmental issues in recent years. Point source emissions of CO2 from industrialised processes such as power generation and cement production account for much of this increase. Direct carbon sequestration and storage...
