Facilitated CO biomethanation by exogenous materials via inducing specific methanogenic pathways

Reply to Comment on “Heterogeneous Catalyst–Microbiome Hybrids for Efficient CO-Driven C6 Carboxylic Acid Synthesis via Metabolic Pathway Manipulation”

“…We have also previously published articles on different additives promoting anaerobic conversion. , However, we would like to emphasize that there are distinct differences between the additives used in previous literatures and the specific hybrid system we designed in this article. The innovative aspects of this article, to be specific: a hybrid approach that combines Pt/Fe 2 O 3 catalysts and microbiome biocatalysts for C1 chain elongation to C6, were about pathway manipulation and construction, not as simple as stimulation or enhancement.…”

Expressing Variable Mass Transfer Coefficients for Gas Fermentation in Trickle Bed Reactor

“…A greater k L a value typically leads to improved reactor performance by increasing substrate availability to the microbes and thereby increasing the rate of reaction and improving the efficiency of utilization of syngas [14]. Thus, mass transfer determination is crucial in ensuring efficient conversion of syngas to biomethane, as it facilitates the distribution of gaseous substrates and nutrients to the microbial cultures responsible for the conversion process [15]. In some instances, mass transfer can limit the overall reaction rate, especially if the contact between the gas phase and liquid phase is insufficient [16].…”
