Potential Production of Biofuel from Microalgae Biomass Produced in Wastewater

Microalgae biomass as an alternative substrate in biogas production

The running down of fossil energy sources makes the production of bioenergy an expected need worldwide. Therefore, energy crops have gained increasing attention in recent years as a source for the production of bioenergy because they do not compete with food crops. Microalgae have numerous advantages such as fast growth rates and not competing with food production. Because of the fast growth, m...

Isolation of microalgae with potential for integrated biomass production and nutrient removal from wastewater

Abstract The present study firstly investigates the variations of microalgae in the constructed wetland. Then one of the potential microalgal species was isolated and cultured in autotrophic and mixotrophic growth to compare the performance on biomass production and to evaluate the ability of wastewater treatment and simultaneous biodiesel production. Scenedesmus sp. was an abundant strain in t...

Influence of starch on microalgal biomass recovery, settleability and biogas production.

In the context of wastewater treatment with microalgae cultures, coagulation-flocculation followed by sedimentation is one of the suitable options for microalgae harvesting. This process is enabled by the addition of chemicals (e.g. iron). However, in a biorefinery perspective, it is important to avoid possible contamination of downstream products caused by chemicals addition. The aim of this s...
