It decreases ammonia content during wet anaerobic digestion by 33% and has a positive economic effect. Dry anaerobic fermentation of chicken manure is possible, but there is still no efficient way to provide it, and additional research is needed.
Sep 16, 2014 · The problem of ammonia accumulation during manure fermentation can be solved by appropriate dilution of the substrate, so that it contains from 0.5% to 3% of dry matter content, however, due to
1~1.5 tons of dry chicken manure (about 2.5~3.5 tons of fresh chicken manure) needs one kilogram of chicken manure starter. And 5~10 kg of rice bran, corn or bran need to added to each kg of starter. After mixing well, you can sprinkle them in ready raw materials. Step 2: Adjusting C/N
2. Fermentation of chicken manure. Chicken manure fermentation is an important step in the preparation of organic fertilizer. Its principle is to use the action of microorganisms to decompose and convert organic matter in chicken manure into organic fertilizer. The fermentation method usually uses aerobic composting.
Jun 12, 2023 · Tylosin concentration exceeding 167 mg/L in the manure highly deteriorated the biomethane productivity due to an accumulation of acetate and propionate in the fermentation medium.
Fermentation 2024, 10, 366 2 of 15 antibiotics can contribute to the selection pressure for antibiotic-resistant bacteria [11,12] and promote the spread of antibiotic resistance genes (ARGs) [13
Mar 5, 2024 · Abstract The paper presents data on the study of the kinetics of gas formation from chicken manure under thermophilic conditions. It was shown that the volume of biogas for 30 days in the control variant did not exceed 85 dm3, whereas with the addition of 10 and 20% of the balanced thermophilic methanogenic association as an inoculate was 150 and 180 dm3, respectively, and the methane content
At an initial pH of 8 and at 55 degrees C, 195 and 157 ml g-VS(-1) of methane was successfully produced from the treated chicken manure and the mixture of treated chicken manure and raw chicken manure in the ratio of 1:1, respectively. In this method, ammonia concentration was maintained at a level lower than 2g-N kg-wet sludge(-1) in the reactor.
Apr 1, 2024 · The risks associated with residual antibiotics in chicken manure, particularly as sources of TCs and ARGs, cannot be understated (Riaz et al., 2020).Their propensity to induce resistance within microbial communities has led to concerns over water and soil contamination (Qiao et al., 2012; Song et al., 2016).
Bolong was founded in 1993,We established Hebi Bolong livestock Husbandry Machinery Co., Ltd. in 2012, an enterprise specialized in R&D production of automatic farm equipment, which takes the practicability and reliability as the starting point.In 2015, the company respond to the national call of environmental protection, then successfully developed a new type of high-temperature aerobic
May 2, 2022 · Batch experiments were performed to evaluate the biohydrogen and biomethane production by co-digestion of chicken manure and food waste in a two-stage mesophilic fermentation process. Results showed that no hydrogen was produced in the first stage of sole chicken manure fermentation, while methane yield was 247.3 mL·g−1-VS.
Jun 1, 2013 · In this work, a long-term methane fermentation process feeding CM containing 10% TS using a continuously stirred tank reactor (CSTR) was performed to investigate the stability, inhibition and recovery of the inhibited reactor.
Advanced Research Journal of Microbiology (ARJM) ISSN 1718-3499, Vol. 6(6), pp. 331-337, September, aimed to produce bioorganic liquidfertilizer from chicken manure and groundnut husks through ...
Nov 11, 2022 · Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies. Considering the wide range of high value applications of VFA, a semi-continuous immersed anaerobic membrane bioreactor (AnMBR) was applied to boost VFA productivity and yield
Jul 18, 2023 · As a result of manure fermentation after pretreatment, 16 to 45% more biogas and 18 to 39% more methane were obtained compared to manure without pretreatment. Biomass in the form of chicken ...
