Third generation biodiesel production from microalgae currently necessitates many stages, some of which are complex and energy consuming, cell disruption is such an example. Microalgal strains which are prime candidates for oil extraction normally possess a robust cell wall which prevents the...

The thermal characteristics under oxidizing atmosphere of several species of microalgae: Nannochloropsis gaditana (NG), Scenedesmus almeriensis (SC) and Chlorella vulgaris (CV) was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) coupled with mass...

This study investigated the effect of three types of catalysts on the yield of biocrude oil from thermochemical liquefaction (TCL) of the microalga, Spirulina platensis. TCL experiments were performed in a 1.8L batch reactor using an alkali metal catalyst (Na2CO3), an alkaline earth metal...

Micro-algae have been recognized as a promising feedstock for biofuel production. Effective combining microalgae cultivation with wastewater treatment can reduce CO2 emissions and the cost of microalgae biofuel production, making it more feasible. However, the biomass and lipid productivity must...

Advanced biofuels, such as those obtained from microalgae, are widely accepted as better choices for achieving goals of incorporating renewables and non-food fuel sources into the transportation sector, and for overcoming land use issues due to biofuel crops. Main challenges are currently the...

Nowadays, microalgae received wide attention due to several advantages for biochemicals and renewable/sustainable biofuels production. Moreover, the utilization of microalgae as robust cellular species for biological nutrient removal from industrial and domestic wastewater streams has been of...

Microalgae are getting more interests from industry and science communities. Applications of these small, unicellular microorganisms are countless: from fourth generation biofuels, through fish feed to pharmaceuticals. Ordinary methods of cultivation may be associated with many problems such as...

Despite the known advantages of microalgae compared with other biomass providers or fossil fuels, microalgae are predominately produced for high-value products. Economic constraints might limit the commercial energetic use of microalgae. Therefore, we identify the LCCs (life cycle costs) and...

Among biofuel production processes using microalgae biomass, biogas generation seems to be the least complex. Nevertheless, its efficiency is hampered due to the hard cell wall. In order to enhance its anaerobic biodegradability, the present investigation evaluated the effect of two...

Illumination factors can affect growth of microalgae and HCO3− fixation. In order to optimize microalgae growth in culture system and HCO3− fixation from wastewater, the effects of light source, light interval on the growth of microalgae, Chlorella sp. and Scenedesmus obliquus sp., were...
