“…Biochar stimulated the growth of some DIET microbes, such as Geobacter, Sphaerochaeta, and Sporanaerobacter species, which further boosted the DIET-based syntrophic metabolism to degrade organic compounds and generate more methane [2]. Zhang et al showed that 5 g/L of biochar greatly alleviated sulfamethazine (SMZ) inhibition through biochar adsorption in the early period of the AD process (0-3 days), and only 0.6% of cumulative biogas production decreased at 20 mg/kg −1 of SMZ (based on TS of manure) [26]. At the same time, the microbial community analysis indicated that biochar significantly facilitated the enrichment of microbes involved in DIET such as Methanothrix and Methanosarcina [26].…”

“…In addition, DIET can facilitate the bioremediation of organic contaminants in soils and waters [24]. Meanwhile, it was revealed that an efficient DIET process in AD not only decreased the inhibition of antibiotics but accelerated the syntrophic metabolism of antibiotics [25,26]. Wang et al have demonstrated that the potential DIET process contributed to enhancing the biodegradation of antibiotics and decreasing the intensive excretion of extracellular polymeric substances (EPS) under antibiotic pressures [25].…”

Efficient conversion of organic waste into low-carbon biofuels such as methane through anaerobic digestion (AD) is a promising technology to alleviate energy shortages. However, issues such as inefficient methane production and poor system stability remain for AD technology. Biochar-facilitated direct interspecies electron transfer (DIET) has recently been recognized as an important strategy to improve AD performance. Nonetheless, the underlying mechanisms of biochar-facilitated DIET are still largely unknown. For this reason, this review evaluated the role of biochar-facilitated DIET mechanism in enhancing AD performance. First, the evolution of DIET was introduced. Then, applications of biochar-facilitated DIET for alleviating antibiotic inhibition and enhancing methanogenesis were summarized. Next, the electrochemical mechanism of biochar-facilitated DIET including electrical conductivity, redox-active characteristics, and electron transfer system activity was discussed. It can be concluded that biochar increased the abundance of potential DIET microorganisms, facilitated microbial aggregation, and regulated DIET-associated gene expression as a microbial mechanism. Finally, we also discussed the challenges of biochar in practical application. This review elucidated the role of DIET facilitated by biochar in the AD system, which would advance our understanding of the DIET mechanism underpinning the interaction of biochar and anaerobic microorganisms. However, direct evidence for the occurrence of biochar-facilitated DIET still requires further investigation.

“…Bacteroidetes and Firmicutes were predominant in all the reactors on day 49 (58.0-83.4%). Bacteroidetes and Firmicutes are bacterial phyla commonly found in a typical anaerobic digestion reactor and are responsible for the degradation and hydrolysis of complex macromolecules by releasing extracellular enzymes [31]. The relative abundance of both phyla was signi cantly higher in the biochar-and spongelled conditions (58.8% and 47.2%, respectively).…”

Anaerobic digestion of compressed water hyacinth juice (WHJ) is one of the appropriate ways to enhance excessively grown water hyacinths. The addition of biofilm carriers is effective in enhancing digestibility as they can retain microorganisms at a high density in the digester. This study evaluated the anaerobic digestion performance in a sequential batch reactor in the presence of a natural carrier, biochar from coffee husks which are representative agricultural waste in areas where water hyacinths are thriving, compared to those with a commonly used carrier (polyurethane sponge) and without a carrier. In the biochar-filled condition, the CH4 production was 471 mL g-VS− 1 and the total organic carbon (TOC) removal efficiency was 88.6%. In contrast, in the no-carrier condition, the CH4 production decreased and the TOC removal efficiency dropped to 54.5%. The porosity of the biochar promoted microbial attachment and biofilm formation. Candidatus Diapherotrites archaeon ADurb.Bin253, which belongs to the symbiotic archaeon Nanoarchaeaeota, was detected in all reactors, suggesting that it contributed to the organic decomposition. The performance of the biochar was comparable to that of the sponge carrier, indicating that the coffee husk–derived biochar can be considered a sustainable and useful carrier for enhancing the anaerobic digestion of WHJ.

Aconitum Brachypodum Diels (AB) is a plant of Aconitum L. The dried roots of AB have analgesic and anti-in ammatory activity. However, the processing is required to reduce toxicity before use because of its high toxicity. Studies on the toxicity, pharmacodynamics, and chemical composition of processed Aconitum Brachypodum Diels. (PAB) are still lacking at present. In this study, the composition changes of AB and PAB were determined by UPLC-QE-Orbitrap-MS. The intensity of diester alkaloids was greatly reduced, while the monoester alkaloids were signi cantly increased. An acute toxicity experiment was used to evaluate the toxicity differences between AB and PAB, while the acetic acid-induced writhing pain experiment and croton oil-induced ear edema experiment were applied to evaluate the analgesic and antiin ammatory properties. The acute toxicity test of AB showed that the median lethal dose (LD50) was 1.37 g / kg, while the maximum tolerance of PAB was 30.0 g/kg. It was apparent that the toxicity of PAB was signi cantly reduced. The alkaloid component of PAB could signi cantly inhibit the mice's ear edema and signi cantly reduce the number of mice writhing. Based on the above ndings, 10 compounds, including songoramine (1), neoline (2), bullatine C (3), dihydroatisine (4), bullatine A (5), maltol (6), 15-Oacetylsongorine (7), 15-O-acetylsongoramine (8), songorine (9), and aldohypaconitine (10) were separated and identi ed from the alkaloid component of PAB. Compounds 4, 6, 8, and 10 were rstly separate from Aconitum. Finally, molecular docking to anti-in ammatory analgesic target protein was carried out. The results showed that the 10 compounds and target proteins had good binding capabilities, wherein 15-O-acetylsongoramine could interact with the key protein Akt1 of Pi3k-Akt pathway and adjust the downstream NF-κB critical pathway to play an anti-in ammatory analgesic effect.
