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
Apr 29, 2023 · However, the study eventually found that anaerobic fermentation of 175 kg of cattle manure with 175 kg of water and 50 kg of poultry manure with 325 kg of water produced 6.33 and 0.83 m 3 /day of biogas, respectively (Recebli et al. 2015). 7.2.3 Characteristics and Composition of Animal Manure
Jan 1, 2020 · A schematic diagram of the techniques and procedures used in the production of fermented feeds for farm animals. Fermentation can be achieved by liquid-or solid-state fermentation that involves either a single-step or a two-step process.
Oct 14, 2020 · It has now passed more than forty years since solid-state fermentation (SSF) research developments have gained importance for the scientific community. After so many years, numerous processes and equipment for SSF were studied and designed focusing on the production of different commercially relevant bioproducts such as enzymes, fermented food, such as Chinese daqu and koji, organic acids
Apr 1, 2023 · Solid-state fermentation (SSF), a microbial fermentation process, is a viable, efficient approach that transforms discarded agro-industrial wastes into a plethora of useful value-added bioproducts. There is growing interest in the application of SSF in valorizing agro-industrial wastes for the production of fermented, protein-rich animal feed
Apr 17, 2023 · The main function of a fermenter is to provide a controlled environment for the growth of microorganisms or animal cells, to obtain a desired product. In designing and constructing a fermenter a number of points must be considered: 1. The vessel should be capable of being operated aseptically for a number of days and should be reliable in long
Apr 15, 2023 · The growing global population and higher living standards instantly demand the transition in the direction of a sustainable food system. A substantial section of means and agricultural lands are presently committed to protein-rich feed production to rear livestock for human consumption. Conversely, accelerated farming activities and the food industry have rendered a drastic increase in waste
Jan 1, 2014 · Over a billion tons of animal manure is produced annually in the US. Animal manure is an excellent plant nutrient source and soil amendment when used properly. Manure contains plant macro- and micronutrients, supplies organic matter, improves soil quality, and maintains or increases soil pH in acid soils. However, nutrients such as phosphorus
Manure Management☆ Amy L. Shober, Rory O. Maguire, in Reference Module in Earth Systems and Environmental Sciences, 2018 Trends in Manure Production. Manure production by species varies widely by region; for example production of goats, sheep, and cattle dominate in Africa (Table 1), cattle production is common in South America and production of all animal types is common in Asia (FAO, 2018).
Apr 16, 2020 · Due to the large quantity and wide range of solid wastes of the biomass, and the dual characteristics of pollution and resource utilization, the energy utilization of anaerobic fermentation can promote its pollution control, so the mixed fermentation technology of solid wastes of agricultural biomass was studied. Corn straw, pig manure, and kitchen waste were selected as solid wastes of
Mar 22, 2023 · The ERS report, Increasing the Value of Animal Manure for Farmers (AP-109, March 2023), uses data from the USDA Agricultural Resource Management Survey (ARMS) to describe current manure production, handling, storage, and use. An extensive review of manure-related research describes existing and emerging technologies that have the potential to
Oct 8, 2020 · Recently, dry anaerobic co-digestion is one of the mechanisms which have been increasingly used to improve the reactor’s performance for treating livestock manure with agricultural crop residues. Due to carbohydrate, protein and lipid existing in agricultural wastes, biogas yield decreased with higher reactor volume when using wet anaerobic digestion. In this regard, the aim of this work was
Sep 1, 2021 · In order to explore the effects of adding biochar on biogas production by high solid concentration anaerobic fermentation of livestock and poultry manure and agricultural safety, this study used pig manure, cow manure and chicken manure as fermentation raw materials, and carried out experiments on biogas production by mesophilic temperature anaerobic fermentation with high solid concentration.
May 18, 2022 · Animal manure is rich in both organic and inorganic phosphorus (P), with inorganic orthophosphates accounting for 45%–90% of the P in manure, which are uptaken by plants (Bittman et al. 2004 ). However, N/P ratio in manure is much lower than the N/P ratio in plants, which causes the problem of excess P in soil.
Jan 6, 2017 · Abstract. Optimization of production medium is required to maximize the metabolite yield. This can be achieved by using a wide range of techniques from classical “one-factor-at-a-time” to modern statistical and mathematical techniques, viz. artificial neural network (ANN), genetic algorithm (GA) etc.
