Apr 27, 2021 · This is where fermentation comes in as a cost‐efficient, versatile and proven technology that extends the shelf life of food products and enhances their nutritional content. Moreover, there is enormous potential in fermentation to further increase efficiency and product range and even create new food products from non‐food biomass.
Jan 31, 2024 · This study investigated the synergistic integration of clean technologies, specifically anaerobic digestion (AD) and struvite precipitation, to enhance nutrient recovery from chicken manure (CM). The batch experiments were conducted using (i) anaerobically digested CM digestate, referred to as raw sample (RS), (ii) filtered digestate sample (FS), and (iii) a synthetically prepared control
Abstract. In upstream bioprocessing, the feed strategy is an important parameter to achieve high cell densities. In this study we optimized high cell density fed-batch fermentation of Escherichia coli (E. coli) using the SciVario twin bioreactor control system equipped with a 1 L glass bioreactor.
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
Feb 24, 2024 · Purpose Co-composting of chicken manure and edible mushroom residue inoculated with oxytetracycline-degrading strain T4 was conducted to reduce the risk of residual oxytetracycline and tetracycline resistance genes (TRGs) to the ecological environment. Materials and Three treatments (CK: without bacteria agent T4 inoculated; AM: 1% bacteria agent T4 inoculated in mesophilic phase; AC
Aerobic fermentation processes demand provision of oxygen at the rate to suciently satisfy the growth need of organism. Aeration is the most important and critical factor for the eciency of
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
Sep 14, 2023 · The brewery industry generates a huge quantity of brewers’ spent grain (BSG) which can pose waste disposal and pollution problems. Anaerobic digestion of BSG, a recalcitrant lignocellulosic waste, is slow but can be enhanced by bioaugmentation, biostimulation and co-digestion to obtain a higher biogas yield. Hence, the effect of inoculum from brewery wastewater sludge (BWWS), iron (III
Jun 1, 2017 · Temperature is one of the key indicators of the progress of composting (Hassen et al., 2001).As shown in Fig. 1, the temperatures of the composting piles progressed through three stages (thermophilic, mesophilic, and maturation stages), where the temperature ranged from 24.0 to 76.2 °C during the composting process.
Jan 1, 2024 · Livestock manure use in agriculture contributes to pollutants like antibiotic resistance genes (ARGs) and resistant bacteria. This practice could potentially facilitate ARGs development in soil ecosystems.
Aug 4, 2023 · Chicken manure and composts derived from it are valuable organic fertilizers that have a positive impact on soil fertility and significantly enhance crop yields.
Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation
Biochar is thought to be good sorbent for heavy metal and exploring ways to increase the efficiency of heavy metal adsorption by biochar is of great importance. Chicken manure biochar was modified with sulfur, hydroxyapatite and MnFe2O4 respectively. The properties and composit
Appl. Sci. 2020, 10, 990 3 of 21 water, inorganic acids—such as sulphuric acid, nitric acid, carbonic acid, and phosphoric acid—which originate from natural waters, chemical industry e uents have the potential to corrode the concrete
Sep 14, 2022 · However, it is not easy to model the fermentation process because each cell in the bioreactor can be viewed as a subsystem of metabolic and signaling networks [22,23]. For fermentation problems, three modeling approaches are generally used: mechanistic modeling, data-driven modeling, and hybrid modeling [20,24]. The mechanistic modeling
