2024/3/11/ · Abstract Ionizing irradiation, as a new pretreatment method for the anaerobic fermentation of organic pollutants, is featured with fast reaction speed, good treatment effect, no need to add any chemical reagents, and no secondary pollution. This study explores the mechanism of improving anaerobic fermentation performance of rice

2023/8/21/ · Polyaluminum chloride (PAC) is used widely and increasingly in wastewater treatment plants, resulting in its inevitably high production in sludge. Previous studies have indicated that the production of short-chain fatty acids (SCFAs) is inhibited by the existence of PAC in sludge anaerobic fermentation, so it is necessary to study how

2019/10/4/ · Fermentation occurs in certain types of bacteria and fungi that require an oxygen-free environment to live (known as obligate anaerobes), in facultative anaerobes such as yeast, and also in muscle cells when oxygen is in short supply (as in strenuous exercise). The processes of fermentation are valuable to the food and beverage

2017/9/27/ · High organic loading rate (OLR) can be achieved in systems with biomass retention by means of high throughput or by a high share of volatile solids (VS) in the

2020/4/16/ · 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,

2022/5/18/ · The attention that high solids anaerobic digestion process (HS-AD) has received over the years, as a waste management and energy recovery process when compared to low solids anaerobic digestion process, can be attributed to its associated benefits including water conservation and smaller digester foot print. However, high solid

2024/1/1/ · Reactor vessels can also affect the fermentation process, and their usage varies based on the type of output needed. Anaerobic fermentation to produce biogas is a microbial-driven process, with various species acting in different stages of the conversion of input material into biogas. Modified ADM1 for high-rate anaerobic co-digestion of ...

2020/1/31/ · The composition of the four experimental diets is shown in Table 1.The control diet (CTR) was a high-concentrate (forage was less than 30%, with 231 g neutral detergent fiber/kg dry matter) total

2024/3/15/ · For the anaerobic fermentation process producing high-value VFAs, limited studies of ML models have been reported. while the daily production of VFAs in the reactor was used as the output. Strategy-2. Considering the cost of monitoring indicators, Strategy-2 only employs pH, ORP, and conductivity as input features to forecast VFAs ...

2023/11/17/ · The results showed that the anaerobic sludge could degrade chitin under both the anaerobic respiration and fermentation modes, with similar degradation rates (7.10 ± 0.96 and 6.96 ± 0.23 C-mg/L·d−1). The open-circuit voltage and output current density could roughly reflect the degradation of chitin in the MFC.

2018/2/1/ · Besides, the functional categories and key genes of amino acid metabolism in a high solid anaerobic fermentation process were investigated by Li et al. (2017). However, less study is conducted on the microbiological mechanism of producing SCOD and VFAs by PS fermentation under controlling pH (i.e. acid- or alkali-treatment).

2021/5/12/ · Amongst these, hydrogen is thought to be an ideal energy source with almost no hydrocarbon and carbon dioxide emissions and high energy output. Among the hydrogen production techniques, dark fermentation (DF) is a promising option for hydrogen production as it is less costly and has more energy recovery potential.

Anaerobic fermentation for biogas production It demonstrates greater yields, increased solid loading capacity, less wastewater output, and improved ... It is important to mention that a fermenter is a vessel that must be designed to support the growth of a high population of microorganisms. Fermenters are usually cylindrical vessels with ...

Bacteria of several gram-positive genera, including Lactobacillus, Leuconostoc, and Streptococcus, are collectively known as the lactic acid bacteria (LAB), and various strains are important in food production.During yogurt and cheese production, the highly acidic environment generated by lactic acid fermentation denatures proteins contained in milk,
