Summary: For the first time, a surface-active amine was used for CO2 capture and in-situ conversion into bicarbonate. Analysis of the CO2 capture capacity data with NMR spectroscopy revealed the influence of PO groups on CO2 solubility, solution pH, and steric effect, establishing the mechanism of bicarbonate generation. The results demonstrated a 54% enhancement in bicarbonate generation under ambient conditions with the optimal PO level (DMAPA-6PO) compared to DMAPA.

Summary: According to the characteristics of power plant flue gas emission and the requirements of reducing CO2 capture cost, CO2 absorption hybrid with microalgae conversion (CAMC) can effectively address the challenges of heat and nutrient consumption. By using bicarbonate solution as a carbon source for mutagenic Spirulina platensis cultivation, the study found that NaHCO3 was a better medium compared to K2CO3 for the CO2 absorption hybrid with microalgae conversion system. The addition of 0.3 mol/L NaHCO3 resulted in the highest biomass dry weight, carbon fixation rate, carbon utilization efficiency, and protein synthesis.

Summary: This study optimized the cultivation conditions for a local microalgae species, Chlorella sp. G3H3-1-2, with high pH-resistant, high growth rate, and high lipid content. It was found that a pH range of 6.0 to 8.0 with glucose as the carbon source resulted in the highest specific growth rate of 1.22 day(-1) for Chlorella sp. G3H3-1-2. However, the highest total FAMEs content of 59% in the biomass of 1.75 g/L was obtained when using the combination of glucose and (NH4)2SO4 at a high pH value of 10.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
