The effects of glucose, sucrose and maltose supplementations on the fermentation performance and stress tolerance of lager yeast (Saccharomyces pastorianus) during high gravity (18°P) and very high gravity (24°P) fermentations were studied. Results showed that throughout 18°P wort fermentation, ferm
2023/8/31/ · A bioreactor, or a fermentation vessel, is a device or system used to cultivate and produce biological. cells, tissues, or organisms in a controlled environment. It functions as a vessel-like
2022/1/1/ · High-performance liquid chromatography is one of the most commonly used analytical tools to monitor fermentation processes off-line. The availability of different chromatographic columns and detection (e.g., UV-Vis or RI) makes HPLC a versatile tool that separates and detects a wide range of different compounds.
2021/1/16/ · The data suggest that D-glucose/D-xylose co-consumption in high-performance D-xylose consuming strains causes the glycolytic flux to saturate. Excess D-glucose is phosphorylated enters the trehalose pathway resulting in glucose recycling and energy dissipation, accumulation of trehalose-6-phosphate which inhibits the hexokinase
2024/4/1/ · Precision fermentation aims to produce food ingredients from abundant and inexpensive substrates by using precise genetic perturbations to rewire metabolic
2024/5/23/ · 1. Fermenter Vessel. A fermenter is a large cylinder closed at the top and bottom connected with various pipes and valves. The vessel is designed in such a way that it allows to work under controlled conditions. Glass and stainless steels are two types of fermenter vessels used. The glass vessel is usually used in small-scale industries.
2024/2/25/ · This high agitation requires baffles to reduce tangential flow, whose flow impedance exacerbates the high power consumption; balancing these demands makes CFD study a useful tool for designing an efficient and productive fermenter configuration.

2024/2/25/ · CFD modeling has widely studied fermenters, and the high power-to-volume ratios (P/V) needed to overcome incomplete mixing or mass transfer have been well demonstrated. 2.6 Modeled equations to predict fermenter hydrodynamics and performance. Table 1 shows the CFD-modeled equations with a complete background in
2022/3/1/ · The fermentation of Pu-erh tea is an ongoing process, therefore, it is necessary to dynamically monitor the changes of these biologically active oligopeptides, free amino acids, and derivatives (OPADs) derived from tea for the control of tea quality. In recent years, high-performance liquid chromatographic (HPLC) coupled with mass ...
The variants displayed the same advantages in a pilot-scale stirred fermenter under high-gravity conditions at 11 degrees C. Microarray analysis identified several genes whose altered expression may be responsible for the superior performance of the variants. The role of some of these candidate genes was confirmed by genetic transformation.
The pitch rate will a˙ect the fermentation performance and ˜avor of the beer. For LalBrew Nottingham™ yeast, a pitch rate of 50 - 100g per hL of wort is suˆcient to achieve optimal results for most fermentations. More stressful fermentations such as high gravity, high adjunct or high acidity may require higher pitch rates and
2022/10/1/ · As shown in Fig. 2 A, the initial pH and TA values of fermented soy milk prepared after inoculation with LAB only, kombucha bacteria only, and mixed LAB and kombucha bacteria at 1:1 mass ratio were 6.78 and 12.34°T, respectively. During the fermentation process, the pH values of fermented soy milk of all groups showed a
2001/10/1/ · Introduction. The generation of municipal solid waste (MSW) amounts to 44,583 t/d in Korea, of which 26.5% is food waste from restaurants, dinning halls, markets and households (MOE, 2000).Food waste is the main source of decay, odor and leachate in collection and transportation due to the high volatile solids (85–95%) and moisture content …
