“…As a bioactive flavonoid, eriodictyol showed many protective effects through the inhibition of oxidative stress (14,15,17,18). At the same time, eriodictyol and its glucoside can protect against cerebral ischemia injury in vitro and in vivo (16,43). To the best of our knowledge, the present study is the first to demonstrate the protective effects of eriodictyol on cardiomyocytes injured by hypoxia/reoxygenation, which indicates its potential application in the prevention of myocardial ischemia and reperfusion injury.…”

Myocardial infarction is a leading cause of mortality worldwide, while myocardial ischemia and timely reperfusion contribute to myocardial injury. The mitochondria are involved in the injury and mediate the apoptosis of cardiomyocytes. In order to develop novel therapeutic approaches for myocardial infarction, the present study evaluated the myocardial protective effects of eriodictyol and investigated relevant mechanisms in H9c2 cardiomyocytes. As a result, eriodictyol was observed to improve the H9c2 cardiomyocyte viability and block the leakage of cytosolic lactate dehydrogenase under hypoxia/reoxygenation. In addition, the dysfunction of mitochondria induced by hypoxia/reoxygenation was ameliorated by eriodictyol through suppressing the overload of intracellular Ca 2+ , preventing overproduction of reactive oxygen species, blocking mitochondrial permeability transition pore opening, increasing mitochondrial membrane potential level and decreasing ATP depletion. Finally, the apoptosis of H9c2 cardiomyocyte induced by hypoxia/reoxygenation was prevented by eriodictyol through upregulation of the expression of B-cell lymphoma-2 (Bcl-2) and downregulation of the expression levels of Bcl-2-associated X protein and caspase-3. These results provided evidence for further investigation on myocardial protection and the treatment of myocardial infarction using eriodictyol.

“…In the Chlorella family, Chlorella sp. and Chlorella vulgaris exhibit the highest CO2R rates and highest lipid productivity (precursor of biodiesel) over others [119][120][121]. Scenedesmus sp., a microalga isolated from a marble mining site, is active at a high CO 2 stream (~15% CO 2 ) [122].…”

Managing the concentration of atmospheric CO2 requires a multifaceted engineering strategy, which remains a highly challenging task. Reducing atmospheric CO2 (CO2R) by converting it to value-added chemicals in a carbon neutral footprint manner must be the ultimate goal. The latest progress in CO2R through either abiotic (artificial catalysts) or biotic (natural enzymes) processes is reviewed herein. Abiotic CO2R can be conducted in the aqueous phase that usually leads to the formation of a mixture of CO, formic acid, and hydrogen. By contrast, a wide spectrum of hydrocarbon species is often observed by abiotic CO2R in the gaseous phase. On the other hand, biotic CO2R is often conducted in the aqueous phase and a wide spectrum of value-added chemicals are obtained. Key to the success of the abiotic process is understanding the surface chemistry of catalysts, which significantly governs the reactivity and selectivity of CO2R. However, in biotic CO2R, operation conditions and reactor design are crucial to reaching a neutral carbon footprint. Future research needs to look toward neutral or even negative carbon footprint CO2R processes. Having a deep insight into the scientific and technological aspect of both abiotic and biotic CO2R would advance in designing efficient catalysts and microalgae farming systems. Integrating the abiotic and biotic CO2R such as microbial fuel cells further diversifies the spectrum of CO2R.

Heavy reliance on fossil fuels has been associated with increased climate disasters. As an alternative, microalgae have been proposed as an effective agent for biomass production. Several advantages of microalgae include faster growth, usage of non-arable land, recovery of nutrients from wastewater, efficient CO 2 capture, and high amount of biomolecules that are valuable for humans. Microalgae Chlorella spp. are a large group of eukaryotic, photosynthetic, unicellular microorganisms with high adaptability to environmental variations. Over the past decades, Chlorella has been used for the large-scale production of biomass. In addition, Chlorella has been actively used in various food industries for improving human health because of its antioxidant, antidiabetic, and immunomodulatory functions. However, the major restrictions in microalgal biofuel technology are the cost-consuming cultivation, processing, and lipid extraction processes. Therefore, various trials have been performed to enhance the biomass productivity and the lipid contents of Chlorella cells. This study provides a comprehensive review of lipid enhancement strategies mainly published in the last five years and aimed at regulating carbon sources, nutrients, stresses, and expression of exogenous genes to improve biomass production and lipid synthesis.
