Summary: The study found that roxithromycin inhibited the growth and chlorophyll synthesis of Chlorella pyrenoidosa before phototransformation, causing oxidative damage. However, after phototransformation, roxithromycin had no significant impact on algal growth and physiological characteristics, suggesting that it may inhibit algae growth by downregulating genes related to chlorophyll synthesis.

Summary: The intensive use of antibiotics has led to the release of large amounts of antibiotic residues into aquatic systems due to inefficient wastewater treatment. Conventional treatments cannot effectively remove emerging contaminants like antibiotics. Algae treatment shows promise as a cost-effective and eco-friendly solution. This study demonstrates the potential of using well-established algal consortia for the removal of antibiotics in wastewater in a developing country context.

Summary: The study aimed to determine optimal conditions for the production of large amounts of microalgae biomass intended for energy purposes, analyzing the effects of lighting type, lighting culture time, and pH of the culture medium on Chlorella vulgaris biomass growth. Optimal conditions were found to be neutral pH with 18 hours of illumination a day.

Summary: High concentrations of CO2 promote growth and photosynthetic capacity in Chlorella strains, and also affect the levels of signaling molecules, inositol polyphosphates, which impact cell signaling and energy levels. Further investigation of the connections between carbon assimilation and cell signaling by polyphosphate inositols in microalgae is important for optimizing their biotechnological applications.

Summary: Researchers have developed a vertical photobioreactor using oval-shaped tubes for the cultivation of microalgae to capture CO2 from flue gas. The results showed that under optimal conditions, this novel photobioreactor achieved high biomass productivity and CO2 fixation efficiency. It also absorbed other minor pollutants from the flue gas, providing additional knowledge for algae cultivation using waste gas sources.

Summary: This study investigated the effect of co-culturing the photobiont and mycobiont in the microbial fuel cell (MFC) cathode on biomass production, lipid generation, and power output. The MFC with co-culture enhanced the lipid output of biomass by 28.33% and had a higher open circuit voltage and specific growth rate compared to algae alone. The co-culture proved beneficial at the MFC cathode in terms of total energy output.

Summary: Microalgae are potential candidates for capturing CO2 and producing biomass. The use of fed-batch culture mode can enhance algal growth rate and CO2 removal efficiency. Low levels of dissolved CO2 limit algal growth, while high levels inhibit it. Chlorella vulgaris grown with 1.62 g L-1 dCO2 showed the best growth performance and nutrient uptake rates.

Summary: Carbon capture and sequestration technologies, such as using algae to absorb CO2 and convert it into biomass, are promising for reducing carbon emissions and producing biodiesel. The performance of these biosystems depends on various conditions, and different steps are involved in producing biodiesel from algae.

Summary: Graphene oxide quantum dots (GOQDs) can convert UV light into available wavelengths for microalgae cultivation. However, their high cost and difficulties in recovery hinder their large-scale application. This study proposes a new strategy of adding GOQDs to the outer sandwich of a reactor for sustainable use. Direct exposure of microalgae to GOQDs can increase biomass production but also cause oxidative stress, while indirect exposure enhances growth without damaging the cells. Overall, indirect exposure of GOQDs is an effective and cost-reducing way to promote microalgae growth.

Summary: The study investigates the role of the lonely guy gene (CvarLOG1) in the unicellular green microalga Chlorella variabilis NC64A, finding that overexpression of CvarLOG1 leads to extended life span, increased biomass and potential applications in the biofuel industry. Transcriptomic analysis shows that genes associated with photosynthesis were upregulated, indicating a possible reason for the increased biomass.

Summary: This study investigated the impact of ethylenediaminetetraacetic acid (EDTA) on the toxicity of boron to the algae species Chlamydomonas reinhardtii, Chlorella sorokiniana, and Chlorella vulgaris. C. vulgaris was the least sensitive to boron in the presence of EDTA, while C. reinhardtii and C. sorokiniana exhibited high sensitivity. The chelation of EDTA with micronutrients reduced their availability for uptake by the algae, leading to increased sensitivity to boron. These findings have implications for assessing and managing boron risk in aquatic ecosystems.

Summary: This study analyzed the physiological and transcriptional responses of Chlorella sp. to chromium (III) oxide nanoparticles (nCr(2)O(3)). The nCr(2)O(3) had adverse effects on cell growth, photosynthetic activity, and caused organelle damage and metabolic disturbance. The production of extracellular polymeric substances (EPS) initially mitigated the damage, but the protective responses were eventually exhausted.

Summary: This study investigated the optimization of growth and physiological condition of Baltic green microalgae strains Chlorella vulgaris and Monoraphidium convolutum. By analyzing different factors in consecutive stages of culture, the researchers identified the most optimal conditions for microalgae growth. The results showed that using natural waters as a base for culture medium significantly improved algal growth.
