This study determined the physicochemical changes and bacterial community succession in the pig manure composting process with microbial inoculant. Microbial inoculant could prolong the thermophilic stage by 2 days and increased the germination index (GI). Analysis with 16S rDNA showed that the Chao
This equipment consists of transmission device, running gear, turning device and other main components. During turning, SEEC wheel type compost turner can blend the raw material and treated pig manure will be moved 0.7 meter to 1 meter away. By this method, you can realize high-efficiency turning and uniform blend.
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
Jun 12, 2023 · Uncultivable soil sample was supplemented with pig manure samples under microcosm experimental conditions and plated on Luria-Bertani (LB) agar incorporated with commercial antibiotics.
Jul 22, 2022 · Pig manure is a reservoir of antibiotics and antibiotic resistance genes (ARGs). The effect of biochar on the variations in physicochemical properties, bacterial communities, antibiotics, ARGs, and mobile genetic elements (MGEs) of compost product during co-composting of pig manure and corn straw have been investigated in this study.
Jan 22, 2024 · The duration required to compost pig manure can vary depending on several factors. With the right conditions and techniques, pig manure can be transformed into nutrient-rich compost within a few months. However, it is important to note that the composting process can take longer under certain circumstances.
In order to study the feasibility of using GM cotton stalks for composting and the changes that occur in antibiotic resistance genes (ARGs) during composting, we supplemented pig manure with GM or non-GM cotton stalks during composting and we compared their effects on the absolute abundances (AA) of intI1, intI2, and ARGs under the two treatments.
In this study, the effects of process parameters on ARGs during aerobic composting of pig manure were explored through data mining based on 191 valid data collected from literature. Machine learning (ML) models (XGBoost and Random Forest) were utilized to predict the rate of ARGs changes during pig manure composting.
Of note, intI1 and two potential pathogens (Mycobacterium and Bacillus) correlated positively to several increased ARGs, implying the possible risks of compost products. Keywords: Antibiotic resistance gene (ARG); Bacterial community; Composting; Compound microbial agent; Mobile genetic element (MGE).
Turning manure is essential to composting manure. Turning compost incorporates oxygen into the system, homogenizes the pile and breaks up clumps. Turning allows more contact of manure with microbes. Producers have various ways to turn the pile. The two most common for turning compost are with a windrow turner (Figure 7) or bucket tractor.
May 1, 2024 · The tested strain X1 was isolated from the fresh pig manure sample after the aerobic compost fermentation process. The solid Luria-Bertani (LB) medium containing 10 mg/L of Cd 2+ and 100 mg/L of Zn 2+ was used to isolate bacteria with heavy metal tolerance. Five grams of the fresh compost sample were oscillated in a triangular flask containing
Jul 1, 2020 · By investigating the profile variation of 36 ARGs and 4 mobile genetic elements (MGEs), the succession of bacterial communities and the change in physicochemical factors during pig manure composting, this study aimed to: 1) determine the environmental behaviors and removal efficiencies of ARGs in pig manure composting; 2) determine the impact
Jan 15, 2021 · Nowadays, composting is a better option to solve these problems. Accordingly, this study explored the effects of co-composting swine manure with different inoculants dominated by Phanerochaete chrysosporium (p), Aspergillus niger (a), and Bacillus licheniformis (b) on the simultaneous removal of multiple antibiotics and resistance genes and
4 Best Compost Machines for Beginner Composters - GreenCitizen. This Countertop Compost Machine Turns Scraps into Compost in . Mar 27, 2024 · The Lomi countertop compost machine makes turning kitchen scraps into compost the easiest thing ever.
Apr 5, 2024 · Start by building a pile with a mix of organic matter, like kitchen scraps, dried grass, leaves, paper, and straw. Add soil and pig manure from the pig farm to the ingredients, and spray the pile with water so it’s moist and not wet. The most important part of composting pig manure is to ensure the pile has high heat.
