Jan 1, 2015 · The fermentation medium consists of sucrose (around 200 g/L) and mineral salts to provide a balanced supply of iron, zinc, copper, magnesium, manganese, and phosphate. The provision of a suitable culture medium is the most critical factor in obtaining a high yield of citric acid. The fermentation is carried out at 25–27°C.
Oct 6, 2022 · During yeast dough fermentation, such as the high-sucrose bread-making process, the yeast cells are subjected to considerable osmotic stress, resulting in poor outcomes. Invertase is important for catalyzing the irreversible hydrolysis of sucrose to free glucose and fructose, and decreasing the catalytic activity of the invertase may reduce the glucose osmotic stress on the yeast. In this
Mar 15, 2023 · Using the synergism strategy, fermentation products with fibrinolytic and angiotensin I-converting enzyme (ACE) inhibitory activities were obtained and evaluated. The fermentation medium contained 1.0% trypsin, 1.0% oyster protein hydrolysate, 2.0% maltose, and 0.5% sodium chloride, with an initial pH of 7.0.
Oct 10, 2023 · 10,000L Mashtun. $185,000 – $250,000. The optimal mash tun size balances production volume, number of batches, and beer diversity. Larger units above 100 hectoliters streamline higher volume. Smaller tuns allow more flexibility. Integrated mash filters or lauter tuns simplify the lautering process.
Apr 10, 2018 · Fed-batch, continuous, and batch fermentation systems can be selected for high efficiency. Continuous and fed-batch systems can handle substrate restriction amid fermentation procedures. Higher efficiency also can be achieved by the immobilization of cells, which can be derived incrementally from the biomass collection in the bioreactor
May 28, 2024 · During the dark fermentation unit with three chambers (each chamber has a working volume of 1 m 3), the dark fermentation system was conducted under an initial pH of 5.5, HRT of 12 h, and 40 °C
Nov 26, 2018 · Accurate determination of the fermentation efficiency value of an industrial unit is therefore essential for evaluation of the performance of an ethanol production process.
Feb 2, 2022 · High-Efficiency Production of Auricularia polytricha Polysaccharides Through Yellow Slurry Water Fermentation and Its Structure and Antioxidant Properties Zhengbin Yang 1,2,3 Yuedan Hu 1,2,3 Jiangli Wu 1,2,3 Jingui Liu 1,2,3 Furong Zhang 1,2,3 Hongya Ao 1,2,3 Yong Zhu 1,2,3 Laping He 1,2,3 Wei Zhang 4 Xuefeng Zeng 1,2,3 *
Dec 18, 2019 · The main objective is achieving a high volumetric productivity (kg product per reactor volume and time unit), which is linked to the biocatalyst concentration (cell density) and the flux of CO and H 2 into the liquid fermentation broth and the cell itself. Reactor design and operational conditions should, therefore, promote maximum cell
