2024/1/1/ · The remediation plant (Pennisetum hybrid) and anaerobic fermentation residues (biogas slurry and biogas residue) were provided by Ganzhou Ruiyuan Biotechnology Co., Ltd. in Jiangxi Province (China), which had a large-scale biogas project (20,000 m 3) for the centralization treatment of animal manures from 34 large-scale farms
2020/10/1/ · For example, cephalosporin C fermentation residue can be converted into biogas, while the biogas and methane yields reached 290 and 200 mL/gTS, respectively [6]. However, the residual antibiotic (erythromycin in this study) unavoidably presents the inhibition effects against the microorganisms and even an ecological risk.
2023/10/19/ · The utilization of biogas and biogas residues is an important objective of animal manure resource management. Regarding the environmental friendliness and economic suitability of utilization modes, previous studies have evaluated and compared biogas or biogas residue individually, which may lead to incomplete environmental and
2022/12/1/ · 1. Introduction. Straw with lignocellulose as the main component is considered to be a suitable feed stock for biofuels and bio-products [1].In recent years, methane fermentation technology is one of the most promising bio-energy production technologies because of its high energy output/input ratio (28.8 MJ/MJ) [2].Although
2024/1/1/ · Anaerobic fermentation to produce biogas is a microbial-driven process, with various species acting in different stages of the conversion of input material into
2022/8/17/ · Purpose As a high-yield by-products of biogas engineering, biogas residue (BR) are limited in the application of soil fertility due to their ecological threat. Therefore, conversing BR into biochar is to be considered. However, whether BR biochar still had ecological risk to soils (especially the widely distributed soils such as Ultisol soil)
2019/5/25/ · In this study, two approaches were used to unravel the microbial community structure of a 10‐ton anaerobic digester designed to treat bovine residues under mesophilic dry fermentation conditions. DGGE was used to target methanogens and a metagenomic approach was used to study the whole microbial community.
This study used biogas residue produced by anaerobic fermentation of food waste as the raw material in large-scale windrow composting. The effects of the addition of a microbial consortium on the physical and chemical properties and stability of composting of biogas residue were studied. The maturit
2010/8/1/ · In practice, this occurs in. agricultural biogas plants. In Figure 11 a model of. installation built in order to produce biogas from. different types of biomass wastes is presented. Thermo
the accumulation of biogas residue in three years reached 350 tons. Managing these biogas residues is a challenge for every farmer. During anaerobic fermentation of pig manure, most of the phosphorus is deposited in biogas residue. The phosphorus content in biogas residue can reach 2–5% (w/w) (Deng et al. 2015), which constitutes a P-rich waste.
2017/3/25/ · Studies showed that fermentation of feed ingredients can promote growth performance , digestibility of amino acids and distiller’s yeast was added to a final content of 10% based on weight. The biogas residue was aerobic fermented 48 h, then dried and crushed. The yield contained 92.01% dry materials, 21.87% crude protein, 6.35% crude
2021/2/13/ · 2.2 Biochar production. Details on BR preparation have been reported previously (Zheng et al., 2018).For biochar production, oven-dried BR samples were placed inside capped porcelain crucibles and loaded into a muffle furnace (KSL-1200X, Kejing Materials Tec.) under N 2 (99.999%) saturated atmosphere (0.5 dm 3 min −1 of flowing
2015/9/1/ · All anaerobic digestion tests were performed in a number of 2.0 L fermentation flasks that were connected to gas bags for collection of biogas.The fermentation flasks were kept in an incubator shaker (30 RPM) working at a given temperature of 37 °C (see Fig. 2 a). 100 ml of the antibiotic residue with or without HTPT
2013/12/15/ · Conclusion could be drawn that the mass percent of cellulose in the biogas residue, which is the remnant produced by anaerobic fermentation using ruminant feces, was above 5% more than that in
Control moisture content. It is advisable to keep the waste content of cow manure between 45% and 65%. because when the moisture content of cow dung is below 30%, the activity of functional bacteria will be reduced. And when it is higher than
