2024/1/1/ · The methane production with lignosulfonate addition was comparable to that without in the first 1–2 d and the last 10–12 d of anaerobic fermentation (Fig. S2). Future studies are highly recommended to shed light on the impact of lignosulfonate on the microorganisms through a long-term reactor with continuous feeding. Moreover, it should ...
Share it! Anaerobic fermentation is a complicated process that is 100% natural and is carried out on microorganisms. Read this BiologyWise article to know what anaerobic fermentation is and some interesting facts about this process. Fermentation is commonly defined as the process in which energy is formed by the process of oxidation of organic
Anaerobic fermentation is widely used to recover different products from food waste, and in this study, the evolution of fermentation products and microbial community along with pH variation was investigated thoroughly using four long-term reactors. Lactic fermentation dominated the system at pH 3.2-4.5 with lactic acid concentration of 5.7-13.

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
2024/1/6/ · Anaerobic fermentation is an environment-friendly method for resource recycling from organic wastes, and followed by storing in 4 °C. The inoculum was taken from a mesophilic anaerobic digestion reactor with long-term stable operation in the laboratory and sterilized at 90 °C for 2 h to eliminate the activity of methanogens. The ...
2024/3/15/ · During the last two decades, a variety of models have been developed to describe the anaerobic digestion/fermentation process. Derived from theoretical, empirical, and statistical approaches, these models can be used to predict biogas production, explain inhibition of process, or simulate liquid–gas interface mass-transfer ( Xu et al., 2015 ).
2023/6/1/ · 1. Introduction. With the improvement in living standards, a large amount of food waste was produced (Hu et al., 2022, Zhang et al., 2010).It is estimated that food waste will exceed 2.28 billion t/a worldwide by 2050 (Pham et al., 2015).Anaerobic fermentation is a feasible way for resource utilization of food waste (Wang et al., 2014).Recently,
Biogas Digester Mixers & Fermentation. Digester mixing maintains homogeneity of the fluid, evenly distributes the bacteria, maintains uniform temperature conditions and prevents the formation of thermal and density layers to maximize biogas production. Conditions inside an anaerobic digester or fermenter are harsh. Flygt submersible mixers are

2024/6/20/ · Summary. Anaerobic conditions are maintained in some ecosystems where the rate of oxygen supply is lower than that of consumption. Organic compounds are removed from anaerobic ecosystems through the concerted action of fermentative and anaerobic respiratory microorganisms. In microbiology, the term ‘fermentation’ can be
