Airlift bioreactors are tower reactors for large-scale aerobic cultures where the mixing of the culture broth is done by the inserted gas via an airlift pump (Fig. 7.5). This pump injects compressed air at the bottom of the discharge pipe, which is immersed in the liquid.
Aug 2, 2023 · 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.
May 23, 2024 · Airlift bioreactors are used for aerobic bioprocessing technology so that they can provide a controlled liquid flow in a recycling system using pumps.
Jun 1, 2023 · Airlift bioreactors (ALBRs), as a type of ALRs, have been applied practically in various biochemical and environmental processes such as microalgae cultivation and protein production (Tagliaferro et al., 2019), polyhydroxybutyrate production (Manikandan et al., 2021), alkane biodegradation (Denis et al., 2017), water and wastewater treatment ...
1 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.
Jun 23, 2021 · A pilot-scale airlift bioreactor (ALBR) system was built and operated continuously for refinery excess sludge (RES) reduction. Combined ALBR and function-enhanced microbes (composed of photosynthetic bacteria and yeast) were integrated into the system.
The airlift bioreactor (ALR) is often used in cases for which the bubble column lacks the operational flexibility or requirements. The airlift bioreactor and bubble column have very similar bubble–bubble interactions and behavior, which leads to almost identical gas flow regimes and progression.
Bioreactors of the airlift type are a promising design for aerobic fermentations. The basic knowledge required for understanding and predicting the performance of these reactors is only now beginning to emerge.
Apr 15, 2010 · ALRs are popular in modern bioprocess research and development and, in many cases, they have found industrial uses. The distinctive characteristics of ALRs are conferred by the fluid dynamics of the liquid-gas or liquid gas-solid mixtures: holdup, liquid velocity, and mixing in the riser, gas separator, and downcomer.
May 19, 2008 · Airlift reactors are popular in the modern bioprocess research and development, over a broad spectrum of processes. Those range from the production of very expensive biochemicals to wastewater treatment.
