TL;DR: In this article, a 0.5 μm porous sparger enables micro-bubble CO2 aeration with bubble size distributions below 150 μm in Sauter mean diameter, correlating with the highest measured mass transfer rates.
Comparative investigation of fine bubble and macrobubble aeration on gas utility and biotransformation productivity.

TL;DR: The observed advantages of microbubble aeration are based on the large volume‐specific interfacial area combined with a prolonged residence time, which results in a high mass transfer performance, less enzyme deactivation by foam formation, and reduced gas consumption, which makes microbuble aerators favorable for application in biocatalysis.

Enhanced CO2 fixation in the biocatalytic carboxylation of resorcinol: Utilization of amines for amine scrubbing and in situ product precipitation
TL;DR: Maximum yields of up to 50% are achieved and are found to correlate with the CO2 loading capacity of triethanolamine and application of quaternary amines for in situ carboxylation product removal by precipitation improves the achievable yields depending on utilized amine concentration.
