Oct 15, 2021 · Occurrence of antibiotic resistance genes (ARGs) in animal manure impedes the reutilization of manure resources. Aerobic composting is potentially effective method for resource disposal of animal manure, but the fate of ARGs during composting is complicated due to the various material sources and different operating conditions.
Feb 10, 2021 · Biological pretreatment outcompetes other pretreatment in terms of low demand for energy and chemicals, with non-toxic output. However, the production of enzymes requires a stable fermentation that might need additional equipment, thus increase the capital cost. 4.4.2. Conventional laboratory achievements
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
The utility model relates to a corrosion-resistant livestock and poultry manure fermentation tank body which comprises a steel cylinder body (1), wherein the upper end of the cylinder body (1) is hermetically connected with a tank cover (2), the lower end of the cylinder body (1) is hermetically connected with a tank bottom (3), and the inner surfaces of the cylinder body (1), the tank cover
Jan 1, 2021 · The fermentation takes approximately 23 up to 25 days. The experiments were performed during the summer and autumn seasons when the ambient air temperature varies from 28 to 45 °C. The biogas can
Dec 31, 2020 · Today, food fermentation can be achieved through two main production . With the first production method, the fermentation process is driven by the autochthonous (native/indigenous) microflora of the raw food materials or processing environment, for instance, sauerkraut, kimchi and certain fermented soy products [20,37,42,43,44].
Jun 5, 2021 · Livestock manure is a major source of antibiotic resistance genes (ARGs) that enter the environment. This study assessed the effects of inoculation with mature compost (MC) on the fates of ARGs and the bacterial community during swine manure composting.
Feb 7, 2022 · Here we show, by engineering crystallographic configurations upon metal matrices adjacent to their passive films, we obtain great enhancement of corrosion resistance of FeCr15Ni15 single crystal
The fermentation chamber was 6 feet deep. The soil was hard and rocky, and RCC boundary wall was constructed around digesters. For isolation of digester, wheat straw was filled in between boundary wall and digester rings. Feeding chamber was at the midpoint of the fresh feed digester (di-gesters1and3).Feedingchamber(3×2×1feet)wasmadeof
Oct 1, 2021 · A relationship between GC degradation and crucial fermentation stages (hydrolysis and acidification) was explored along with correlations between microbiome structures and important fermentation parameters (pH and temperature). Finally, possible degradation pathways of GCs were proposed, revealing a toxicity change during co-fermentation.
May 18, 2022 · Anaerobic digesters are large fermenters with mechanical mixing, heating, and gas collection and can be different types based on their mode of operation, such as: Batch. Semi-continuous. Continuous. The reactor type for biogas production should be chosen depending on the waste characteristics, particularly the particle solid contents or total
Feb 1, 2011 · The fermenter was operated a room temperature (approximately 20–21 °C) and uncovered, and consisted of a polypropylene tank with a conical bottom. The fermenter was mixed using a 32° pitched-blade turbine mounted to a 15 W AC motor (USM315-401W/3GN36KA; Oriental Motors, San Jose, CA). The fermenter was decanted (from the bottom) and fed
Dec 20, 2021 · Biogas production from manure is of particular value in regard of lowering greenhouse gas emissions and enhancing nutrient re-circulation. However, the relatively low energy content and the characteristics of manure often result in low degradation efficiency, and the development of operating strategies is required to improve the biogas yield and the economic benefits. In this study, the
