“…NBs in water can persist for a longer duration with adequate dissolved gases, which could promote the better growth of microbes and their productivity [73]. Ye et al [74] proposed to boost oxygen diffusion via MNBs; the oxygen transfer coefficient and rate of MNBs were 0.160 min −1 and 0.382 kg•m −3 •h −1 (about four times and five times greater than those of conventional aeration, respectively). For example, in the work of Guo et al, CO 2 -MNBs had a promoting effect on the growth of Sinomicrobium oceani WH-15 at MNB concentrations of 5-10% in water, whereas the inhibitory effect appeared from 20% [75] because a high concentration of MNBs produced a large number of hydroxyl radicals and other reactive oxygen components, which was unfavorable to the microorganisms [76].…”

The production of bio-based succinic acid through microbial CO2 fixation and conversion has gained significant attention as a promising approach to mitigate greenhouse gas emissions. However, the low CO2 utilization efficiency limits the efficient biosynthesis of succinic acid. Therefore, it is crucial from environmental and economic perspectives to enhance the efficiency of CO2 utilization in bio-succinic acid production. This review comprehensively covers the introduction of biosynthetic pathways for microbial CO2 fixation and the conversion of CO2 to succinic acid, as well as the challenges associated with CO2 supply and utilization effectiveness. Moreover, strategies including genetic and metabolic engineering for CO2 fixation, extracellular supply methods of CO2 and some potential technical approaches for CO2 capture (such as micro-nano bubbles, CO2 adsorption material and biofilm) are summarized and presented.
