Summary: The study investigates the variations in biological response of Chlorella vulgaris to different Mg2+ concentrations. The growth curve, photosynthesis pigments, total protein, carbohydrates, and enzymatic parameters were examined. The results show that 5 mg/L Mg2+ is optimum for biomass production, while 15 mg/L Mg2+ is optimum for protein and carbohydrate production.

Direct Electrochemical Leaching Method for High-Purity Lithium Recovery from Spent Lithium Batteries

Liming Yang et al.

Summary: Recovering lithium from spent ternary lithium batteries (T-LIBs) is a promising approach for sustainable T-LIB development. Chemical leaching methods, widely used in current lithium recovery, pose serious environmental threats and result in low Li recovery purity. In this study, we present a direct electro-oxidation method for lithium leaching, achieving high Li recovery purity of nearly 100% without secondary pollution.

Enhancing biolipid production and self-flocculation of Chlorella vulgaris by extracellular polymeric substances from granular sludge with CO2 addition: Microscopic mechanism of microalgae-bacteria symbiosis

Xiaolei Liu et al.

Summary: This study explored the responses of microalgae Chlorella vulgaris to extracellular polymeric substances (EPS) extracted from aerobic granular sludge (AGS). It was found that the performance of C. vulgaris was effectively enhanced with AGS-EPS treatment, resulting in increased biomass production, lipid accumulation, and flocculation ability. This research provides novel insights into the microscopic mechanism of microalgae-bacteria symbiosis and has implications for wastewater valorization and carbon-neutral operation of wastewater treatment plants.

Fluorescence descriptors for algal organic matter and microalgae disintegration during ultrasonication

Waris Khan et al.

Summary: This study investigated the effects of ultrasonication power on microalgae disintegration and the release of algal organic matter, utilizing advanced organic matter characterization tools. The results showed that tryptophan-like, tyrosine-like, and humic-like substances had significant correlation with changes in algal organic matter, and increased with the power of ultrasonication. The study presents a novel approach to spectroscopic descriptors for real-time tracking of microalgae disintegration and the release of algal organic matter during ultrasonication.

Proton Self-Enhanced Hydroxyl-Enriched Cerium Oxide for Effective Arsenic Extraction from Strongly Acidic Wastewater

Wenbin Hu et al.

Summary: In this study, arsenic was recovered from strongly acidic wastewater using a hydroxyl-enriched CeO2 adsorbent. The adsorption mechanism in a strongly acidic solution was investigated. The experimental results showed that the adsorption capacities of the adsorbent for As(III) and As(V) were the highest reported values so far. It was also found that the hydroxyl groups on the CeO2 surface could buffer hydrogen ions and promote the adsorption of arsenic. The feasibility of using hydroxyl enriched CeO2 for recovering arsenic and acid was demonstrated.

Summary: Third generation micro algae feedstock cultivation and fuel production offer sustainable and economic benefits due to their microscopic nature. Each step in producing micro algae biodiesel can be optimized to improve production efficiency. Utilizing optimized micro algae biodiesel blends in IC engines requires calibrating engine parameters for ideal performance. Studies have shown that closed type reactors are effective for continuous cultivation of micro algae. Techno-economic analysis suggests that maintenance costs need to be significantly reduced for commercial availability of micro algae biodiesel.

Water reuse and growth inhibition mechanisms for cultivation of microalga Euglena gracilis

Mingcan Wu et al.

Summary: The study found that microalgae can only be cultivated through two growth cycles with purified and reused water, with significant growth inhibition observed in the third cycle. As the number of water reuse cycles increases, the Cl- concentration gradually rises in the cultivation water, leading to inhibition of microalgae growth. Additionally, the study identified humic acid (HA) as the main inhibitor of microalgae growth, and demonstrated that HA can be efficiently removed by treatments such as activated carbon and advanced oxidation processes.
