2023/3/28/ · This reduction may be due to the oxidation caused by residual oxygen in the fermentation system during a short fermentation period . The total phenolic contents in the blueberry system and the mixed blueberry and whey protein system fermented with L. plantarum 67 and L. casei 54 were slightly decreased upon exposure to proteases in

2010/1/1/ · In this sense, a fermentation system is a complex and dynamic set of microor ganisms or cells converting the materials and energy into more biomass and metabolic products within a controlled

2019/7/1/ · 1. Introduction. An ectopic fermentation system (EFS), composed of complex microbial communities including functional thermophilic microbes mixed with litter, was developed to overcome the problem of pollution from existing farm wastewater systems (Guo et al., 2013).The proposed EFS successfully settled farm wastewater and prevented

2024/3/2/ · Microbial cell factories, renowned for their economic and environmental benefits, have emerged as a key trend in academic and industrial areas, particularly in the fermentation of natural compounds. Among these, plant-derived terpenes stand out as a significant class of bioactive natural products. The large-scale production of such

2023/9/15/ · To reduce the negative impacts caused by OSW, different countries have adopted various actions. The top five countries with the largest number of publications are China (904), the United States (259), Germany (125), Japan (109) and India (107), accounting for 67.3% of the total number of papers in the world (Fig. 1).China has the

2015/1/1/ · The goal of secondary fermentation (maturation) is to balance the final beer flavour, especially to reduce diacetyl and its precursors by conversion into acetoin and 2,3-butanediol. During maturation, beer also reaches final attenuation, which is accompanied by a moderate cell growth comparing to primary fermentation.

Contaminants such as dirt, debris, and water can enter the hydraulic fluid and degrade its quality. This contamination can cause friction and blockages within the system, leading

The Low Fermentation Eating diet is easy-to-follow, completely nutritionally sustainable, and allows patients to return to eating that feels normal and not overly restrictive. Developed by Dr. Mark Pimentel and Dr. Ali Rezaie, Discover the benefits of low-fermentation eating with Goodlfe. Our expert guide explains how this diet can improve gut

2022/4/1/ · In this study, we explored the pathways and mechanisms of nitrogen (N) transformation driven by functional microbes carrying key genes in an ex situ fermentation system (EFS). Temperature and N content were found to be the most important factors driving variation in bacterial and fungal communities, respectively; Bacillus became the

2023/1/1/ · Oxidation reduction potential. Oxidation reduction potential reflects the metabolic activity of the microorganisms involved in the fermentation process. It is defined as the tendency of a molecule to acquire electrons [26]. A specific approach is used to manipulate and control redox potential for the production of desired metabolites.

2013/1/1/ · Another important role of water is to reduce the temperature of the fermentation system by evaporation. The heat absorption of water vaporization is relatively large, and the thermal conductivity of the solid substrate is low; consequently, evaporation is one of the effective means of adjusting the temperature in most fermentation systems.

2020/10/6/ · On the future fermentation. Future fermentations will be open, continuous and automatically controlled with fresh water and energy saving. The production strains will be extremophiles engineered by synthetic biology. Microbial fermentations produce chemicals, materials, biofuels, foods and medicines for many years.

2024/2/1/ · The reduction in fermentation time had a negative effect on the conversion of the substrate, while the highest biohydrogen production was achieved when the HRT was 0.5 h. such as the complex design and high maintenance costs. Moreover, the native microbial species in the fermentation system could not ferment substrates for long

2017/3/11/ · Although the indigo reduction process is performed via natural fermentation and maintained under open-air condition, the indigo-reducing reactions continue for 6 months (on average) or longer. Identifying the mechanism underlying the maintenance of this process could lead to the development of a novel, long-lasting,

2023/11/1/ · Excess sludge fermentation and the addition of sludge fermentation products could enhance the nitrogen removal, and excess sludge treatment was simultaneously achieved with external sludge reduction ratio of 39%–50% (Liu et al., 2021a, Zhang et al., 2022a). However, these processes required multiple reaction units, and …
