Summary: This study aimed to optimize the bioprocess condition for microalgal lutein production. The 3X:3X ratio macro-and micronutrients showed the highest impact on biomass and lutein yields. Temperature at 30 degrees C increased lutein production but reduced biomass. An optimal light intensity of 10 k lux and a lower salinity level were beneficial for lutein production. The Chlorella sorokiniana Kh12 strain exhibited high lutein yields and has potential for commercial production.

Summary: Microalgae-based technologies can effectively remove organic micropollutants (OMPs) from wastewater, but the impact of wastewater characteristics on the removal is not well understood. This study evaluated the removal of sixteen OMPs by Chlorella sorokiniana cultivated in three types of wastewater. The results showed that the removal efficiency varied depending on the wastewater type, with longer retention time enhancing the removal of some OMPs. Wastewater soluble COD and biomass concentration were found to be the major factors affecting OMPs removal.

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 investigates the potential of UV/gamma-radiation for enhancing lipid production in Chlorella sorokiniana. The results show that growth, chlorophyll content, and photosynthesis efficiency decrease in a dose-dependent manner after irradiation. Transcriptional profiling reveals the modulation of photosynthetic and DNA repair/replication genes under UV and gamma radiation. Upregulated fatty acid biosynthesis genes coincide with increased total lipid accumulation under UV and gamma radiation. Ascorbic acid supplementation reduces UV and gamma radiation-induced lipid accumulation, indicating ROS as a major driver. Fatty acid analysis shows that UV favors the accumulation of saturated lipids, while gamma radiation treated lipids have a higher accumulation of essential omega-3 fatty acid.
