The fermentation performance of the printed hydrogel inks was tested for both bacterial (E. coli) and yeast (S. cerevisiae)-laden gels testing the production of 2,3-butanediol (a), l-DOPA (b), ethanol (c) and a peptide antibiotic (d). The production (pre- and post-preservation) is demonstrated in (a), (b), and (d). The production of ethanol from a year-long fermentation re-use process was evaluated using cell-laden hydrogel lattices (pictured top left in (c). Scale bar: 1 cm). Data are mean ± s.d.; n = 3 biological replicates for (a), (b) and (d); n = 4 biological replicates for (c). Source data are provided as a Source Data file.
