Biogas Production based on Thermophilic Methanogenic
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 dm 3, whereas with the addition of 10 and 20% of the balanced thermophilic methanogenic association as an inoculate was 150 and 180 dm 3, respectively, and the methane
Manure biostabilization by effective microorganisms as a way
Feb 10, 2022 · 3.1 Effects on chicken manure. It is common practice in poultry to overfeed chickens to a minimum weight of 2 kg before entering the market. This practice usually results in a large generation of manure with a high protein content along with other nutrients such as minerals and carbohydrates . These nutrients can be converted into a high
Performance evaluation of a novel anaerobic digestion
Jun 1, 2017 · The effect of reducing HRT CM on CH 4 fermentation of chicken manure was studied. • High content of ammonia was the main inhibition factor at HRT CM of 52 days. • Reduce in HRT CM relaxed the inhibition of high ammonia at OLR of 6.0 gVS/L/d. • The performance deterioration occurred as HRT CM decreased to 10 days.

May 28, 2018 · Species Succession Was Driven by High Temperature in the Two Chicken Manure Composts. This study revealed the composition of the dominant functional microbiota in chicken manure composts. In the two chicken manure composts, Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes were the
Dry Anaerobic Digestion of Chicken Manure: A Review
Chicken manure co-fermentation regularly has better results than chicken manure fermentation as a monosubstrate. The low methane yield was observed only for studies that used switchgrass (2 mL/g VS) , straw (4.34 mL/g VS) , and glycerol after biodiesel production (6.34 mL/g VS) . In general, methane output in co-fermentation was in the range
Dynamic bacterial assembly driven by Streptomyces
Jun 16, 2020 · High-throughput sequencing technology and PICRUSt (phylogenetic investigation of communities by reconstruction of unobserved state) were applied to examine the microbial population dynamics during the composting of dairy manure and rice straw in a static composting system to provide a better understanding for bacterial community composition and

Jun 12, 2023 · High ammonia level (total ammonia nitrogen, TAN > 3 g/L) is the primary bottleneck and is one of the main factors affecting microbial community structure and the methanogenic pathway in the anaerobic digestion of chicken manure.
How to ferment chicken manure? - Fertilizer machine and
Jan 20, 2021 · If chicken manure is not fully decomposed during fermentation, it is not organic fertilizer, but is garbage. It will bring many harms, such as burning roots and seedlings on crops, causing soil salinization, breeding root knot nematodes and other harms. Chicken manure is fully fermented and decomposed, which is a very important process for
Mesophilic methane fermentation of chicken manure at a wide
Jun 1, 2013 · High solid methane fermentation of chicken manure was investigated. • Ammonia inhibition was the main problem for stable operation. • The ammonia inhibitive sensitivities for different reactions were evaluated. • Methanogenesis, acidogenesis and hydrolysis were simulated by models. •
Combined anaerobic digestion of chicken manure and corn straw
Nov 29, 2022 · The focus of this study is to explore the optimal ratio of chicken manure and straw co-fermentation to improve the methane production efficiency, and to analyze the mechanism of microbial diversity change and its synergistic effect by using the dynamic change process of molecular biology and the change of related hydrolytic enzyme activity, to
The screening of early warning indicators and microbial
Jun 1, 2021 · Anaerobic digestion of chicken manure (CM) with high nitrogen content is easily suffered inhibition of ammonia, especially under thermophilic and high organic loading rate (OLR) condition. To screen the early warning indicators for instability, thermophilic digestion of CM was conducted in a bench-scale reactor (working volume 55 L) under OLR

Fermentation process of chicken manure organic fertilizer
The equipment and technological for processing chicken manure into organic fertilizer are mainly divided into pre-fermentation and later deep processing. In real customer cases, how can fermentation be used to achieve high utilization rate of chicken manure organic fertilizer, reasonable fertilizer nutrients, easy absorption, and achieve the ideal state?
