Correction to: Physiological and stoichiometric characterization of ethanol-based chain elongation in the absence of short-chain carboxylic acids (Scientific Reports, (2023), 13, 1, (17370), 10.1038/s41598-023-43682-x)

Abstract

Correction to: Scientific Reportshttps://doi.org/10.1038/s41598-023-43682-x, published online 13 October 2023 The original version of this Article contained errors in the Discussion section, where reference 34 was incorrectly cited as reference 25. Consequently, “Spirito et al.²⁵ also observed a decreased conversion rate when feeding a chain-elongating reactor microbiome with mainly ethanol. This could explain why previous studies with shorter incubation times reported no metabolic activity in the absence of acetate^25,35. The mechanism that underlies this change in rate remains elusive. Spirito et al.²⁵ proposed a thermodynamic constraint on the rate due to increased hydrogen partial pressures, but in our experiments pH₂ was low due to continuous sparging and we still observed low rates.” now reads: “Spirito et al.³⁴ also observed a decreased conversion rate when feeding a chain-elongating reactor microbiome with mainly ethanol.
