Fermentation parameters of Peptostreptococcus productus on gaseous substrates (CO, H sub(2)/CO sub(2))

Intrinsic growth and substrate uptake parameters were obtained for Peptostreptococcus productus , strain U-1, using carbon monoxide as the limiting substrate. A modified Monod model with substrate inhibition was used for modeling. In addition, a product yield of 0.25 mol acetate/mol CO and a cell yi...

Description
Summary:Intrinsic growth and substrate uptake parameters were obtained for Peptostreptococcus productus , strain U-1, using carbon monoxide as the limiting substrate. A modified Monod model with substrate inhibition was used for modeling. In addition, a product yield of 0.25 mol acetate/mol CO and a cell yield of 0.034 g cells/g CO were obtained. While CO was found to be the primary substrate, P. productus is able to produce acetate from CO sub(2) and H sub(2), although this substrate could not sustain growth.
