Advancements on process regulation for microalgae-based carbon neutrality and biodiesel production

Indigenous microalgae strains characterization for a sustainable biodiesel production

“…Since CO 2 and HCO 3 can be utilized by microalgae cells but CO 3 2− can hardly be assimilated, a method that can efficiently control microalgae suspension pH to 6–10 is useful to improve carbon availability, thus improving CO 2 fixation efficiency. [ 36 ] This could explain the LCS and LCN growth improvement since the 11 th day due to pH decreasing under 10 (Figure 1).…”

Metal biosorption onto non-living algae: a critical review on metal recovery from wastewater

“…Using wastewater as a microalgae culture medium can reduce the water footprint by around 35%, alleviate some of the costs associated with nutrient supplementation and decrease greenhouse gas emissions. 60,61…”

Influence of pH and dissolved oxygen control strategies on the performance of pilot-scale microalgae raceways using fertilizer or wastewater as the nutrient source

“…Although more research on this topic is required, the simultaneous pH/DO control system that was developed reduced the CO 2 flow to biomass ratio by up to 20% when using freshwater plus fertilizer. However, it is known that the dissolution of CO 2 from the gas to the liquid phase is limited by a low mass transfer coefficient, limiting its availability for microalgae (Wu et al, 2023), so further studies are necessary to improve the mass trasfer capacity. In the case of the airflow to biomass ratio, different behaviour was observed (Fig.…”
