Jul 1, 2014 · Aerobic submerged fermentation is the primary liquid-state acetic acid fermentation method used in industrial vinegar production and has advantages such as high yield and high efficiency (Gullo et
Jul 12, 2023 · Organisms break down organic molecules, such as glucose, through the common processes of cellular respiration and fermentation (Figure 1). Cellular respiration is generally described as an aerobic process, requiring oxygen, which yields the most possible ATP generated from one molecule of glucose.
May 15, 2020 · The dissolved oxygen concentration was controlled at 30% of saturation for aerobic fermentation and at 0–5% for microaerobic fermentation, first by changing the agitation speed between 300 and 900 rpm; after which, the supplied air was enriched with pure oxygen up to 40% for aerobic fermentation and minimal use of pure oxygen for microaerobic
Sep 23, 2022 · Gluconic acid is a widely used food and beverage additive, but its production suffers from low efficiency and high cost. In this study, a preferable gluconic acid biosynthesis method without repeated seed culture was proposed and developed using the superior performance of Gluconobacter oxydans.
Mar 8, 2022 · 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.
Jul 26, 2020 · These type of fermenters are commonly employed for aerobic bioprocessing technology.
