May 23, 2024 · 2. Airlift fermentor. The airlift reactor is generally used for gas-liquid or gas-liquid-solid contact devices. It is also known as a tower reactor. A bioreactor using an airlift system divides the fluid volume into two zones to improve circulation, oxygen transfer, and equalize forces in the reactor
Airlift reactors have been successfully employed in nearly every kind of bioprocess—bacterial and yeast culture, fermentations of mycelial fungi, animal and plant cell culture, immobilized enzyme and cell biocatalysis, culture of microalgae, and wastewater treatment.
Aug 2, 2023 · What is an Airlift Bioreactor? An airlift bioreactor is a specialized type of bioreactor used for growing various biological cultures, including bacteria, yeasts, algae, animal cells, and plant cells. It operates on a novel principle that distinguishes it from conventional bioreactors.
Feb 14, 2012 · In the case of the 21253 strain of Corynebacterium glutamicum, the course of the airlift fermentation in the bioreactor can be divided in 4 phases. The first phase is characterized by exponential growth of the organism (as long as there are no restrictions of any nutrient).
Jun 1, 2023 · Introduction. Airlift reactors (ALRs) are a unique type of bubble column reactors (BCRs) with a simple design and flexible capacity that performs dual aeration and mixing functions consisting of the riser, downcomer, gas separator, and bottom zones.
agitated stirred-tank fermenters, airlift fermenters are easier to scale up, require less energy to operate and are more adaptable to cultures that are shear sensitive.
Dec 8, 2023 · Airlift bioreactors, with their distinct design and efficient gas-liquid mixing capabilities, play a crucial role in optimizing microbial fermentation processes. In this practical guide, we’ll explore key strategies to enhance the performance of airlift bioreactors in microbial fermentation, drawing comparisons with stirred tank reactors when ...
