Hot prospects: harnessing thermophilic microbes for syngas fermentation
Trends in BiotechnologySyngas fermentation is emerging as a promising avenue for the sustainable production of fuels and chemicals. Primarily consisting of carbon monoxide (CO), hydrogen, and carbon dioxide, syngas can be produced by the gasification of sustainable feedstocks such as waste or biomass.

Mass transfer measurements for syngas fermentation
, 2020 A general scale-up correlation is developed for the volumetric gas-liquid mass transfer coefficient (k[Subscript L]a) in stirred-tank reactors (STRs) for oxygen transport using results from the literature and the current study. Power data for the dispersion of air in water by a six-bladed Rushton impeller are obtained by measuring electrical power, and
