AI Article Synopsis
- The study focused on the mixotrophic microalgae Isochrysis 3011 and its growth in aquaculture wastewater using glycerol, examining various initial concentrations and light intensities.
- It was found that the optimal initial concentration was 0.4 g L and the best light intensity was 60 µmol m s, leading to higher growth rates in mixotrophic cultures compared to autotrophic ones.
- The mixotrophic cultures achieved a biomass yield of 0.17 g L d and significantly removed 73.39% of total nitrogen and 95.61% of total phosphorus, indicating their potential for enhanced wastewater treatment and ecological benefits.
Article Abstract
This research of mixotrophic microalgae Isochrysis 3011 with glycerol was combined with the treatment of aqua-cultural wastewater, different initial concentrations, and optimized light intensities. The algae growth rate, removal efficiencies of total nitrogen (TN) and total phosphorus (TP) were determined. Results showed that the suitable initial concentration was 0.4 g L, and the optimum light intensity was 60 µmol m s. The growth of the mixotrophic group was better than that of the autotrophic culture. The biomass yield of the mixotrophic group with glycerol was 0.17 g L d, and the removal rates of TN and TP were 73.39% and 95.61%, respectively. The content of total lipid and total protein in mixotrophic group were higher than the values of the autotrophic group. This indicates that aquaculture wastewater treatment with mixotrophic bait microalgae can obtain superior micro-algal biomass, which is also a potential technology for wastewater utilization and ecological protection.

Mixotrophic dinoflagellates frequently cause harmful algal blooms (HABs) in eutrophic waters that contain diverse dissolved organic matter (DOM), especially intensive mariculture areas. Compared to the extensive investigation of phagotrophy and single organic molecule uptake by causative species, we have limited knowledge about the capability of mixotrophic dinoflagellates to utilize in-situ DOM in mariculture waters and its contribution to HABs. Here we use filtered in-situ mariculture water as the sole medium to examine the physiological response of Prorocentrum donghaiense to the natural mariculture DOM.

Increasing nitrogen level is one of the most serious environmental problems in global natural waters, disturbing the stability of function and structure of aquatic ecosystem. As important functional group, mixotrophs with plastic metabolism modes perform high adaptations under changing environments, potentially with positive biogeochemical consequences. Here we focus on the trophic plasticity of a model eukaryotic microorganism, mixotrophic Ochromonas under increasing nitrogen and tested the role of osmo-mixotrophy (= mixotrophy) on the physiology of Ochromonas.

Current strategies primarily utilize heterotrophic or mixotrophic bioreduction for the simultaneous removal of Cr(VI) and NO from groundwater. However, given the oligotrophic nature of groundwater, autotrophic bioreduction could be more appropriate, though it remains notably underdeveloped. Here, an autotrophic bioreduction technology utilizing biochar (BC)-assisted zero valent iron (ZVI) is proposed.

Ocean alkalinity enhancement (OAE) is currently discussed as a potential negative emission technology to sequester atmospheric carbon dioxide in seawater. Yet, its potential risks or cobenefits for marine ecosystems are still mostly unknown, thus hampering its evaluation for large-scale application. Here, we assessed the impacts OAE may have on plankton communities, focusing on phytoplankton and microzooplankton.
