Sep 10, 2022 · Ectopic fermentation systems can also reduce the relative abundance of resistance genes in the simultaneous processing of livestock feces and urine (Shen et al., 2021). Straw can be used as a padding material in EFS and promotes a higher concentration of dissolved nitrogen, which in turn enhances the conversion of fermented waste into useful
Apr 15, 2021 · This study investigated the fate of antibiotic resistance genes (ARGs), metal resistance genes (MRGs), and class 1 integron-integrase gene (intI1) during thermophilic fermentation of swine manure in an ectopic fermentation system (EFS), which has been regarded as a novel system for efficiently treating both feces and urine.
Bokashi fermentation is the only solution that avoids all of the problems listed above. Bokashi Pet Cycle Fermentation Systems safely and rapidly transform pet waste into a product that restores nutrients and microbes to the soil for ornamental plants, making it the better, simple choice for pet waste disposal.
Sep 15, 2023 · The two-stage process can not only remove the VFAs in the fermentation waste liquid, but also generate clean and easy-to-use biomass energy at the same time. However, the performance of the system in long-term operation and its process economy still need to be further studied.
Jan 20, 2024 · Anaerobic digestion is a process through which bacteria break down organic matter—such as animal manure, wastewater biosolids, and food wastes—in the absence of oxygen. Anaerobic digestion for biogas production takes place in a sealed vessel called a reactor, which is designed and constructed in various shapes and sizes specific to the site
Sep 3, 2024 · The expanding field of alternative proteins represents a transformative approach to addressing global food security and sustainability challenges. Among these, fermentation-derived alternative proteins cultivated from microorganisms such as fungi, bacteria, and algae offer a promising avenue for sustainable protein production. This review explores the selection and utilization of raw materials
Apr 1, 2024 · In recent years, ex situ fermentation system (EFS) has become increasingly popular for managing livestock waste. It can function dynamically through successive supplementation of collected animal manure and farm wastewater, and completes the resource transformation and harmlessness of waste (mitigating the need for raw manure transportation
biochar in anaerobic fermentation systems. It covers the preparation and characteristics of biochar, its main effects on anaerobic fermentation systems, its impact on the fermentation process of different substrate types, and the underlying mechanisms of its effects. Furthermore, this paper explores the potential for further research
Oct 20, 2024 · Total methane emissions from enteric fermentation in livestock farming could reach 737.5 kt. Fig. 3 b shows the methane emissions from enteric fermentation of different livestock in 12 municipalities and 103 county level administrative units. Methane emissions from enteric fermentation in livestock decreased from east to west.
Feb 8, 2022 · Shi et al. conducted a study on the fermentation of kitchen waste by Clostridium beijerinckii NCIMB 8052 for the production of biobutanol and showed that the butanol yield was only 5.96 g/L without the addition of any nutrients, and the addition of pH buffer increased the butanol yield and Wang et al. investigated the feasibility of direct
Aug 19, 2024 · Food waste, including leftover rice from making onigiris, is turned into high-value animal feed through fermentation (Credit: Rachel Nuwer)
Apr 29, 2023 · Animal waste treatment system is a Diversity and dynamics of the bacterial community involved in pig manure biodegradation in a microbial fermentation bed system ...
Jan 18, 2022 · As an effective treatment technology for livestock farming wastes, the ectopic fermentation bed system (EFS) provides a new means of treating human waste and producing organic fertilizer from
This review article presented the current status and traditional agricultural waste (livestock manure and crop straws) utilization , the art of aerobic fermentation process including ultrahigh temperature fermentation and composting.
Oct 1, 2010 · In order to complete the degradation of organic substrates, a two-stage systems coupling hydrogen fermentation with methane production is recommended for treating substrates such as livestock waste and food waste [38], [42], [77].
