2023/3/8/ · Livestock manure is a major carrier that stores and transmits antibiotic resistance genes (ARGs). The aim of this study was to identify the crucial environmental factors that result in the change in relative abundance of ARGs and MGEs to explore effective to reduce the occurrence of ARGs. Th

2024/1/22/ · The experiment was set up using pots with volumes of 10 L, replicating the storage conditions on farms. The matrices (i.e., digestate, manure, and slurry) were collected from three different farms as follows: digestate from a conventional pig breeding farm, slurries from an organic pig breeding farm, and manure from an organic cow

2014/3/1/ · 1. Introduction. During the manufacturing of cane sugar, a large amount of molasses is produced. Sugar refineries typically use molasses to produce alcohol, and for 1 ton of alcohol produced, 13–15 tons of wastewater (i.e., MAW) are typically generated.MAW contains approximately 88% molasses (Jain et al., 2002), and its components vary with

2017/6/3/ · This is consistent with previous studies (Chen et al. 2017; Li et al. 2020a, b), in which they were found to be the dominant taxa in biogas fermentation system that uses pig manure as the raw

2021/1/1/ · Request PDF | Microbial community and function in nitrogen transformation of ectopic fermentation bed system for pig manure composting | In this work, agricultural wastes were treated by

fermentation by three main phases. 1.2 Mechanism of biogas fermentation: A) Groups of Biogas microbes - Volume of fermentation chamber = V f d) Volume of hydraulic chamber = V H e) Volume of sludge layer = Vs ... Pig manure 0.561 Horse droppings 0.200 ∼ 0.300 Green grass 0.630 70

Composting at high temperatures is the key to benefiting from the “black gold” properties of compost without any of the risks of raw pig manure. There are lots of people who

Biogas is produced by the activities of bacteria that breaks down the biodegradable components of the manure in the absence of oxygen in an airtight chamber. The process is called anaerobic digestion. Anaerobic digestion is the microbial fermentation of substrate in the absence of oxygen. This results in a mixture of gases comprising methane

2014/9/1/ · The batch anaerobic co-digestion of PM and DSS was carried out in five PM/DSS VS ratios: 1:0, 0:1, 2:1, 1:1, and 1:2. The co-digestion was performed in 250 mL serum bottles capped with natural rubber sleeve stoppers, and the working volume of the bottle is 150 mL.In comparison to German biogas plants with 8–12% TS, the

2014/1/2/ · In recent years, many waste products have been studied, such as pig manure (Shen et al., 2014), dietary fibers (Gultemirian et al., 2014) and jackfruit (Gultemirian et al., 2014). In these cases

Molasses alcohol wastewater (MAW) is difficult to be bio-treated and converted into biogas. In this study, MAW mixed with pig manure (PM) in different ratios was co-digested. Biogas production, chemical oxygen demand (COD) removal and the structure of microbial communities were monitored in the proc

2024/3/14/ · The HTP of the prepared pig manure was conducted in a reaction kettle with a working volume of 1 L. Heat transfer oil was used as the medium to conduct heat to the reaction kettle. In each reaction kettle, 0.5 L of pig manure (Table 1) containing a mix of antibiotics, including 2.39 mg/L SDZ, 2.88 mg/L OTC, and 0.47 mg/L ENR, was added

Improper treatment of penicillin fermentation fungi residue (PFFR), one of the by-products of penicillin production process, may result in environmental pollution due to the high concentration of penicillin. Aerobic co-composting of PFFR with pig manure was determined to degrade penicillin in PFFR.

Aerobic fermentation is eective in livestock manure compositing because of reduced time and space requirements 18 . Researchers are attempting to enhance aerobic fermentation techniques to address

In vitro fermentation and measurement of noxious gas concentration Two experiments were conducted to investigate the effects of BA on odorous gas emissions from pig manure under anaerobic condition. The in-vitro trials were carried out in glass reaction chamber to facilitate anaerobic fermentation with air circulation and stirring device
