Summary: In this study, the short-term photosynthetic response of suspended Chlorella sorokiniana to limiting light intensity and CO2 concentration was investigated using a novel CO2-based photosynthesis monitor. The results showed that light intensity had a significant impact on photosynthesis, while CO2 limitation severely affected the efficiency of photosynthesis.

Summary: The study revealed that a light intensity of 100 mu mol m(-2)s(-1) enhances the photosynthetic efficiency of Chlorella sorokiniana SVMBIOEN2 and effectively removes chemical oxygen demand from dairy wastewater; meanwhile, a high light intensity of 150 mu mol m(-2)s(-1) can reduce the kinetic energy of chlorophyll a, influencing the dynamics of photosystem II reaction centers.

Summary: This study investigated the impact of three trophic modes on the growth parameters and biochemical composition of Chlorella species. The results showed that mixotrophic cultivation using an agro-industrial by-product stimulated the growth of all species, yielding high amounts of protein-rich biomass. The study also provided insights into the proteome of Chlorella cells cultured under molasses supplementation conditions.

Summary: Microalgae, specifically Chlorella sorokiniana SU-9, can be cultivated heterotrophically to produce high-quality proteins comparable to fishmeal and soybean meal. Optimal culture parameters were determined, and under these conditions, SU-9 exhibited high biomass content, protein content, and productivity. The production cost of SU-9 can be significantly reduced, making it a potential protein substitute in aquafeed.

Summary: This study investigated the effects of surgical mask exudates (SMEs) in wastewater on microalgal cellular responses. The findings showed that SMEs significantly inhibited nutrient uptake and photosynthetic activities, disrupted peroxisome biogenesis, induced oxidative stress, and destroyed the structure of cell membrane. The exposure to SMEs also affected carbon fixation pathways, suppressed ABC transporters, and promoted oxidative phosphorylation processes. These findings contribute to our understanding of the effects of SMEs in wastewater on microalgae and improve the practical relevance of microalgae wastewater bioremediation technology.

Summary: This study successfully demonstrated the concurrent production of astaxanthin and lipids using Chlorella sorokiniana in an ELAPB under mixotrophic conditions. Fe2+ supplementation and the role of reactive oxygen species in astaxanthin production were identified, along with the production of unsaturated fatty acids with excellent biodiesel properties. The study highlighted the economic viability and environmental sustainability of simultaneous high-value product synthesis, showcasing the commercial potential of microalgae-based biorefinery processes.

Summary: In this study, the heterotrophic growth of Chlorella sorokiniana and Chlorella kessleri using crude glycerol as the carbon source was investigated. The effects of different organic carbon addition modes on the lipid and protein content of the biomass, fatty acid distribution, and fatty acid methyl ester (FAME) properties were studied. The results showed that C. sorokiniana had higher lipid productivity compared to C. kessleri, making it a better option for biodiesel production.

Summary: This study investigated the potential hazards of MnO2 nanorods (NRs) on the green microalgae Chlorella sorokiniana during long-term exposure. High concentrations of MnO2 NRs significantly reduced the cell number and induced an increase in chlorophyll content in the algal cells. Long-term exposure to high concentrations of NRs also caused a decrease in primary and secondary metabolites. The findings provide important insights into the potential hazards of MnO2 NRs on aquatic ecosystems.

Summary: This study revealed the multi-targeted responses of the model wastewater microalgae, Chlorella sorokiniana, to FNA exposure. The findings showed that FNA negatively influenced microalgal growth and photosynthesis, increased oxidative stress, and altered gene expression. These results are crucial for understanding the stability of the MBCP system and its potential application in wastewater treatment.

Summary: The study revealed that in the mixotrophic culture of C. sorokiniana, heterotrophy becomes more important than autotrophy as cell density increases, but autotrophy regains dominance when organic carbon is depleted. The increase in algal biomass and light conditions are key factors in determining the contribution ratio of autotrophy and heterotrophy during mixotrophic culture.

Summary: The study found that Rhizobium sp. maintained dominance in the bacterial community and promoted the growth of C. sorokiniana in open cultivation, while Achromobacter sp. gradually lost its dominance. Continuous addition of Rhizobium sp. to the culture significantly increased the growth of C. sorokiniana.
