Jun 1, 2021 · The increasing consumption of poultry in China has resulted in a dramatic development of poultry breeding industries, which led to the accumulation of large amounts of chicken manure (CM). Composting is an effective method for decreasing the amount of CM and simultaneously producing biofertilizer.
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
Jul 1, 2018 · Thirteen days co-conversion of 1000 kg of chicken manure inoculated with one million 6-day-old BSFL and 10 9 CFU Bacillus subtilis BSF-CL produced aging larvae, followed by eleven days of aerobic fermentation inoculated with the decomposing agent to maturity. 93.2 kg of fresh larvae were harvested from the B. subtilis BSF-CL-inoculated group
Nov 12, 2021 · Traditional chicken manure fermentation is mostly natural composting or exposure, which is not only time consuming but also susceptible to weather, resulting in uncontrollable quality and environmental pollution. This research aims to build a smart solar chicken manure fermentation system to control the conditions of chicken manure fermentation effectively, improve quality, and solve the
The presented results show the technical possibility to use chicken manure as a single substrate for an anaerobic process and demonstrate how to overcome the limitations of the use of substrates with high nitrogen content. Keywords . Chicken manure; ammonia inhibition; anaerobic digestion; ammonia stripping . INTRODUCTION
Nov 1, 2005 · DOI: 10.1016/J.BIORTECH.2005.01.033 Corpus ID: 21206580; High yield of poly-gamma-glutamic acid from Bacillus subtilis by solid-state fermentation using swine manure as the basis of a solid substrate.
Nov 29, 2022 · Böjti et al. increased methane yield by 24% by extracting water from chicken manure to improve C/N and then co-fermenting it with corn silage and other feeds, and verified the sustainability of co-fermentation. Microbial community structure is an important factor to maintain the stable operation of anaerobic fermentation.
Apr 1, 2016 · The aim of this study was to determine the effectiveness of microbial preparation and Yucca schidigera in the removal of odorous volatile compounds from poultry manure as well as to evaluate antimicrobial properties of these amendments. It was demonstrated that the combined treatment of poultry manu
Sep 24, 2009 · Anaerobic digestion of energy crops, residues, and wastes is of increasing interest in order to reduce the greenhouse gas emissions and to facilitate a sustainable development of energy supply. Production of biogas provides a versatile carrier of renewable energy, as methane can be used for replacement of fossil fuels in both heat and power generation and as a vehicle fuel. For biogas
Jan 2, 2024 · Soil microbial composition. The diversity of microbial communities was observed in the solid and liquid samples before and after fermentation, as well as in the unprocessed manure before solid
It is also called solid-state anaerobic digestion. This process is used to produce biogas from dry stackable biomass through dry fermentation. Solid animal manure, biowaste, and food waste are suitable for dry fermentation in a fermenter and occurs in the fermenter-boxes of bioreactors. Solid-state digesters are the name given to these systems.
Nov 29, 2023 · Anaerobic fermentation of organic waste, such as livestock manure, in biogas projects is an environmentally friendly and effective treatment method. The resulting biogas, mainly composed of methane, is a combustible gas with energy properties, while the digestate, containing nutrients such as nitrogen (N), phosphorus (P), potassium (K), and other organic matter, can be used for agricultural
Dec 19, 2021 · Substrate A had a slightly higher BMP value as compared to substrate B , which is in line with the content of poultry manure. Compared with cattle manure, poultry manure have been reported to have somewhat higher BMP values (180–280 ml CH4/g VS) (Huang and Dhih, 1981; Pratt et al., 2014; Ruile et al., 2015).
Sep 20, 2023 · Promising for managing poultry manure (PM) include converting poultry manure through pyrolysis to biochar, which can be used for soil applications. The overall goal of this study was to determine the effects of poultry manure-derived biochar and compost on the soil and growth of cherry tomatoes. The biochar obtained at 475 °C was characterized by a relatively high organic matter
