From: Dynamics of dark fermentation microbial communities in the light of lactate and butyrate production

Sample ID Experiment Day of passage/replicates Sample name in Fig. 3 Fermentation substrate /products description
MLA-3-AC MLA 3/pooled A+C MLA 3 A and MLA 3 C The main non-gaseous fermentation products of molasses were lactate and ethanol, concentration of butyrate was very low
MLA-9-AC MLA 9/pooled A+C MLA 9 A and MLA 9 C The main fermentation product of molasses supplemented with acetate and lactate was butyrate; lactate as a substrate was efficiently utilized
LA-3-BC LA 3/pooled B+C LA 3 B and LA 3 C Lactate as a substrate was partially metabolized
LA-18-AB LA 18/pooled A+B LA 18 A and LA 18 B The main fermentation product of the medium containing exclusively lactate and acetate was butyrate; lactate as a substrate was efficiently utilized
