“…After 10 days of culturing, the concentration of CH 4 increased from 60.36% ± 4.28% to 79.73% ± 6.98% with a red-blue light intensity ratio of 2:8, to 81.32% ± 7.14% with a red-blue light intensity ratio of 3:7, to 82.14% ± 7.13% with a red-blue light intensity ratio of 5:5, and to 80.58% ± 7.52% with a red-blue light intensity ratio of 7:3 (Figure 4a). The concentration of CH 4 in biogas is an important indicator of biogas quality (Mesbah et al, 2019). These results show that Treatment 1 had the best improvement effect on biogas quality with a red-blue light ratio of 5:5, which was in agreement with the conclusions of Yan and Zheng (2014), who proposed that adjusting the ratio of red-blue light intensity can improve the grade of biogas.…”

In this study, biogas and biogas slurry were simultaneously treated using two symbiotic systems: Chlorella vulgaris-Ganoderma lucidum-S395-2 (endophytic bacteria) and Scenedesmus obliquus-G. lucidum-S395-2. The influence of different mixed illumination (red and blue) intensity ratios on the algal symbionts' extracellular carbonic anhydrase activities was investigated, as well as the rates of microalgal growth and photosynthesis. The treatment performance was simultaneously assessed in terms of the efficiency of organic matter or nutrient removal and the level of CO 2 absorption. The results indicated that red-blue light combinations with an intensity ratio of 5:5 were optimal. When comparing the performance of the two symbiotic systems, the C. vulgaris-G. lucidum-S395-2 symbiont co-culture system achieved significantly improved photosynthetic rates, biomass growth, and treatment effects. Under the optimal treatment conditions, the organic matter and nutrient removal rates were 81.06% ± 7.06% for chemical oxygen demand, 82.32% ± 7.18% for total nitrogen, and 82.98% ± 7.26% for total phosphorus. In addition, the rate of CO 2 removal from biogas was 63.38% ± 5.35%. Practitioner Points• The red and blue light intensity ratio of 5:5 showed the best removal performance.• C. vulgaris-G. lucidum-S395-2 system obtained the best photosynthetic performance.• The carbonic anhydrase activity had positive effects on CO2 removal performance.Prof. Yongjun Zhao will handle correspondence at all stages of refereeing and publication, also post-publication.Meiying Yang and Xuechang Dong contributed equally to this work.Yongjun Zhao is a member of the Water Environment Federation (WEF).

“…This is because about 50% of the dry weight of microalgae comes from CO 2 consumed for photosynthesis. On the other hand, the concentration of impurities such as CH 4 in biogas is also a key index for evaluating biogas (Mesbah et al 2019). On days 3, 7 and 10 during treatment experiment (Treatment 1), CH 4 , CO 2 , H 2 O, and O 2 concentrations in biogas changed according to the change in concentration GR24 (Figure 4).…”

This study aimed to determine the best fungi to form the algal-bacterial-fungi symbiotic system and identify the optimal conditions for the synchronous processing of biogas slurry and biogas. Chlorella vulgaris (C. vulgaris) and endophytic bacteria (S395-2) isolated from it and four different fungi (Ganoderma lucidum, Pleurotus ostreatus, Pleurotus geesteranus, and Pleurotus corucopiae) were used to form different symbiotic systems. Four different concentrations of GR24 were added to systems to examine the growth characteristics, the content of chlorophyll a (CHL-a), the activity of carbonic anhydrase (CA), the photosynthetic performance, the removal of nutrients, and the biogas purification performance. The results suggested that the growth rate, CA, CHL-a content, and photosynthetic performance of the C. vulgaris-endophytic bacteria-Ganoderma lucidum symbiosis were higher than the other three symbiotic systems when 10-9 M GR24 was added. The highest nutrients/CO2 removal efficiency 78.36 ± 6.98% for chemical oxygen demand (COD), 81.63 ± 7.35% for total nitrogen (TN), 84.05 ± 7.16% for total phosphorus (TP) and 65.18 ± 6.12% for CO2 was obtained under the above optimal conditions. This approach will provide a theoretical basis for the selection and optimization of an algal-bacterial-fungi symbiotic system for biogas slurry and biogas purification.

“…Biogas upgrading at various 5-deoxystrigol concentration for four treatments CH 4 content was an important indicator to evaluate the quality of biogas (Mesbah et al, 2019), and the CH 4 content in biogas increased with the removal of carbon dioxide. The key to biogas purification using microalgae technology was the carbon sequestration efficiency of microalgae strains (Kim et al, 2011).…”

The treatment of biogas slurry by microalgae technology has the characteristics of low cost, environmental protection, and high efficiency. In this paper, the effects of four microalgae technologies, namely, monoculture of Scenedesmus obliquus (S. obliquus), co‐culture of S. obliquus–activated sludge, co‐culture of S. obliquus–Ganoderma lucidum (G. lucidum), and co‐culture of S. obliquus–G. lucidum–activated sludge, on the treatment of biogas slurry were investigated. In addition, the effects of 5‐deoxystrigol (5‐DS) concentration and mixed light wavelengths (red–blue light intensity ratio) on nutrient removal and biogas upgrading were also investigated. The results showed that 5‐DS significantly promoted the growth and photosynthetic performance of the microalgal system. The best purification performance could be achieved by co‐cultivation of S. obliquus–G. lucidum–activated sludge when the 5‐DS concentration was 10−11 M, and the red–blue light intensity ratio was 5:5 (225:225 μmol m−2 s−1). The maximum average removal efficiencies for chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), and carbon dioxide (CO2) were 83.25 ± 7.87%, 83.62 ± 7.78%, 84.19 ± 8.25%, and 71.68 ± 6.73%, respectively. The co‐culture technology of S. obliquus–G. lucidum–activated sludge had great potential and superiority in removing nutrients from biogas slurry and upgrading biogas at the same time. The results of this study will provide a reference for the simultaneous purification of wastewater and upgrading of biogas using microalgae technology. Practitioner Points S. obliquus–G. lucidum–activated sludge consortium showed the best removal performance. 10−11 M 5‐DS greatly promoted the purification performance. Removal efficiencies of COD, TN, and TP were more than 83%.
