Microalgae biotechnology is a promising pathway to cope with CO 2 emission and energy
crisis due to high CO 2 fixation rate and lipids productivity. However, bottlenecks of high …

The boost of the greenhouse gases (GHGs, largely carbon dioxide–CO 2) emissions owing
to anthropogenic activity is one of the biggest global threats. Bio-CO 2 emission reduction …

Hydrogen sulphide (H 2 S) removal from biogas is of high relevance as it damages
combustion engines used for heat and power generation and causes adverse public health …

Microalgae cultivation in wastewater has received much attention as an environmentally
sustainable approach. However, commercial application of this technique is challenging due …

In the recirculating aquaculture systems (RAS), waste management of nutrient-rich
byproducts accounts for 30–50% of the whole production costs. Integrating microalgae into …
