abstract = {Synthetic microbial cocultures carry enormous potential for
applied biotechnology and are increasingly the subject of
fundamental research. So far, most cocultures have been
designed and characterized based on bulk cultivations
without considering the potentially highly heterogeneous and
diverse single-cell behavior. However, an in-depth
understanding of cocultures including their interacting
single cells is indispensable for the development of novel
cultivation approaches and control of cocultures. We present
the development, validation, and experimental
characterization of an optochemically controllable bacterial
coculture on a microcolony level consisting of two
Corynebacterium glutamicum strains. Our coculture combines
an l-lysine auxotrophic strain together with a
l-lysine-producing variant carrying the genetically
IPTG-mediated induction of l-lysine production. We
implemented two control approaches utilizing IPTG as inducer
molecule. First, unmodified IPTG was supplemented to the
culture enabling a medium-based control of the production of
l-lysine, which serves as the main interacting component.
Second, optochemical control was successfully performed by
utilizing photocaged IPTG activated by appropriate
illumination. Both control strategies were validated
studying cellular growth on a microcolony level. The novel
microfluidic single-cell cultivation strategies applied in
this work can serve as a blueprint to validate cellular
control strategies of synthetic mono- and cocultures with
single-cell resolution at defined environmental conditions.},
