2023/8/28/ · The purpose of this experiment was to evaluate changes in fermentation quality, chemical composition, aerobic stability, anti-nutritional factors, and in situ disappearance characteristics of various protein-based total mixed rations. Soybean meal (control, non-fermented), fermented cottonseed meal (F-CSM), and fermented rapeseed

2023/1/1/ · Li et al. (2022c) studied 36 kinds of herbal residues in the anaerobic fermentation of alfalfa, and they proposed that the increased bioactive ingredients may play a critical role in improving the fermentation quality. Therefore, it was hypothesized fermentation would change the active ingredient content and modify the pharmacological

2024/2/20/ · Performance and mechanisms of zero valent iron enhancing short-chain fatty acids production during thermophilic anaerobic fermentation of waste activated sludge. Author and 5 mL were sampled daily to investigate the effect of different ZVI additions on the SCFAs yield and quality. ... The results were consistent with the

Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that's performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation and cellular respiration begin the same way, with glycolysis.

2022/3/8/ · The fermenter design requires enhanced efficiency and authentication of the desired parameters with a high-quality product at a low cost. The fermenter’s strategy and mode of operation are focused on the output of microorganisms, the product’s cost, the condition required for the anticipated product development, and the scale of production.

2023/4/14/ · The scale-up technology of anaerobic fermentation stirring equipment is worthy of attention. Computational fluid dynamics (CFD) simulations were used to study the scale-up of anaerobic fermentation mixing under different solid content conditions. The applicability of different scale-up criteria was analyzed by investigating the relative

2024/3/13/ · Change of methane production in anaerobic process. The statistics of gas production and cumulative gas production during the anaerobic fermentation stages are shown in Fig. 1.The results indicated that within a certain range, an increased sludge percentage positively influenced anaerobic fermentation gas production (Fig. 1b). The

2021/8/19/ · The study evaluated the impact of fermentation with Bacillus sp. on the nutritional quality of soybean meal (SBM) and the changes of bacterial community structure during fermentation. High protease-producing strains were screened to degrade SBM macromolecular protein and anti-nutritional factors (ANFs). Unsterilized SBM then

2022/7/1/ · The fermentation quality of silage was indirectly enhanced by attenuated UV radiation. In this work, ambient UV radiation was halved during oat growth while keeping the remaining anaerobic fermentation variables consistent. Bacterial communities, microbial population dynamics, in vitro gas emissions, and silage chemical

2022/2/1/ · The test period was at least 10-day long until the SCFAs production was no longer increased. Each fermenter received 1.5 L of the above mentioned concentrated sludge. One fermenter was operated without pH adjustment and served as control (R0), while two fermenters were firstly controlled at pH 10, via the addition of 3 mol/L NaOH.

2024/2/20/ · In the realm of large-scale production, the importance of ensuring a consistent yield and quality cannot be overstated. The inherently variable nature of food waste, especially noticeable in fruit and vegetable waste due to seasonal fluctuations, The laboratory's anaerobic fermenter, designed for food waste, boasts an effective volume of
