From: Microbial production of butyl butyrate: from single strain to cognate consortium

Fig. 3

Schematic representation of possible microbial consortium approaches for efficient BB biosynthesis. Light grey color and light orange in (a) and (b) represent carboxylic acids- and alcohols-producing strains, respectively. The bright purple color (a) represents commercial lipase enzymes supplementation while in (b) stands for lipase heterologously expressed in one or both strains as an alternative to undergo esterification reaction. c Approach using a cognate consortium comprising butanol-producing strain and butyric acid-producing strain. Butyrate produced in the medium is converted by butyryl-CoA synthase into butyryl-CoA precursor. AAT represents alcohol acyltransferases involved in the last step to catalyze butyryl-CoA and butanol substrate into biosynthetic BB
