Summary: Lipid-accumulating microalgae, such as Chlorolobion sp. and Chlorella sp., showed increased lipid yield and decreased biomass production under nitrogen-starved culture conditions. The obtained algal biodiesel exhibited high concentrations of saturated and monounsaturated fatty acid methyl esters, making them suitable for biodiesel production. Additionally, the biodiesel properties of the two microalgae met the set specifications of biodiesel standards EN 14214 (European) and ASTM D6751 (American), indicating their potential as raw materials for biodiesel production with superior fuel quality.

Summary: This study investigated the removal of nutrients from swine wastewater digester effluent (SWDE) by microalgae Coelastrella sp. and the production of Coelastrella sp. in the presence of oxytetracycline (OTC) and zinc (II). The mechanisms of OTC and zinc (II) stress on microalgae were discussed by analyzing the removal performance of SWDE and biochemical characteristics of microalgae. The results showed that the presence of zinc (II) decreased the removal efficiency of ammonia nitrogen and biomass yield of microalgae in the presence of OTC. The presence of zinc (II) also promoted the accumulation of lipids in microalgae, while the presence of OTC increased the unsaturation of fatty acid methyl ester.

Summary: Marine Chlorella pyrenoidosa can produce H2 under nitrogen deprivation condition, and photorespiration plays an important role in H2 production. The use of a photorespiration inhibitor leads to a decrease in H2 production and oxygen evolution. Photorespiration plays a crucial role in protecting photosystem II and enabling more photosynthetic electrons to be provided for hydrogenase.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
