The atmospheric CO increase is considered the main cause of global warming. Microalgae are photosynthetic microorganisms that can help in CO mitigation and at the same time produce value-added compounds. In this study, , , and were cultivated under 0.035 (air), 5 and 10% (v/v) of CO concentrations in air to evaluate the performance of the microalgae in terms of kinetic growth parameters, theoretical CO biofixation rate, and biomass composition. Among the microalgae studied, presented the highest values of specific growth rate ( = 1.28 d), maximum productivities ( = 0.28 g Ld), and theoretical CO biofixation rates (0.56 g Ld) at 10% CO. The highest oil content was found at 5% CO, and the fatty acid profile was not influenced by the concentration of CO in the inflow gas mixture and was in compliance with EN 14214, being suitable for biodiesel purposes. The impact of the CO on cells' viability/cell membrane integrity evaluated by the flow cytometry is quite innovative and fast, and revealed that 86.4% of the cells were damaged/permeabilized in cultures without the addition of CO.

To explore the effects of arbuscular mycorrhizal fungi (AMF) on the growth of legume crop, pot and field experiments with soybean were conducted. Treatments of inoculation (+AMF) and non-inoculation with AMF (-AMF) were set up for the pot experiment, and AMF mycelium non-limited and limited for the field experiment. Results of the pot experiment showed that inoculation with AMF significantly increased soybean aboveground biomass (16.

This research work proposes an innovative water resource recovery facility (WRRF) for the recovery of energy, nutrients and reclaimed water from sewage, which represents a promising approach towards enhanced circular economy scenarios. To this aim, anaerobic technology, microalgae cultivation, and membrane technology were combined in a dedicated platform. The proposed platform produces a high-quality solid- and coliform-free effluent that can be directly discharged to receiving water bodies identified as sensitive areas.

CO emissions and the large quantity of lignocellulosic waste generated by industrialized nations constitute problems that may affect human health as well as the global economy. The objective of this work was to evaluate the effects of using CO and pentoses on the growth, protein profile, carbohydrate content and potential ethanol production by fermentation of Chlorella minutissima biomass. CO and pentose supplementation can induce changes in the microalgal protein profile.

Understanding and optimizing the microalgae growth process is an essential prerequisite for effective CO2 capture using microalgae in photobioreactors. In this study, the kinetic characteristics of microalgae Chlorella vulgaris growth in response to light intensity and dissolved inorganic carbon (DIC) concentration were investigated. The greatest values of maximum biomass concentration (Xmax) and maximum specific growth rate (μmax) were obtained as 2.
