Overview

Functional genomics study uncovers genetic regulators of biofilm formation in Cupriavidus necator, highlighting cyclic-di-GMP signaling as a key target for bioprocess engineering.

Key Points

To identify genetic determinants that control biofilm growth and surface attachment in the bioprocess bacterium Cupriavidus necator under heterotrophic conditions.
Cultivated a high-density mini-Tn5 transposon insertion library (26,185 clones) in a microfluidic flow-cell system on fructose for 168 hours, followed by deep sequencing of biofilm-associated cells.
Constructed a markerless deletion mutant of candidate gene B2043 (encoding a dual GSDEF/EAL domain protein) and characterized its attachment and biofilm architecture under static and flow-cell conditions.
Identified 12 genes with elevated insertion frequencies in biofilms, including the ferrous-iron uptake system (feoA/feoB), galU, and the putative c-di-GMP-metabolizing gene B2043.
Under static conditions, the ΔB2043 mutant showed a 1.69 ± 0.06-fold increase in biofilm-associated biomass compared to wild-type (p = 5.16 × 10^-15).
Under flow conditions, ΔB2043 attached faster, initiated exponential growth ~10 hours earlier, reached biovolume plateau ~16 hours earlier, and developed distinct tower-like biofilm architectures.
