To reduce the degree of complexity, stoichiometry of carbon conversion was used for XK (R4), the PP pathway (R5), the upper part of glycolysis (UG) (R9; combining PFK and FBA) and for the lower part of glycolysis (LG) up to ethanol formation (R10).
Profile of observed end products (carbon dioxide, lactate, acetate, ethanol) is consistent with the presence of required enzymes in pyruvate conversion pathways, while detection of hydrogen in gas phase is consistent with hydrogenases and oxidoreductases detected in this organism.
This paper evaluates two different coal conversion pathways – combustion and gasification – and their potential to provide low-cost, low-carbon power from coal.
The present work describes a novel central pathway engineering method that has been designed with the aim to increase the carbon conversion rates under oxidizing conditions in L. lactis fermentations.
carbon conversion efficiency.
High (> 99%) carbon conversion.
Carbon conversion ranged between 35.4 and 44.8%.
CGE represents the carbon conversion and HGE represents the hydrogen conversion in the process.
The carbon conversion was in the range between 81%and90%0%.
Complete carbon conversion and energy conversion efficiency of 66% could be obtained with sufficient input power.
