To isolate a robust cellulose-producing bacterium and build a modular genetic toolkit enabling rational, external control over bacterial cellulose biosynthesis.
Isolated and characterized a robust bacterial strain, Komagataeibacter rhaeticus iGEM, under low-nitrogen conditions and toxic chemical exposures.
Sequenced the full genome of K. rhaeticus to establish a genomic foundation for rational bioengineering.
Constructed a modular genetic toolkit to introduce synthetic gene circuits for functionalizing and patterning heterologous gene expression in the cellulose matrix.
K. rhaeticus iGEM demonstrated robust cellulose yield, stable growth in low-nitrogen environments, and high tolerance to toxic chemicals.
Modular genetic circuits successfully enabled external transcriptional control and spatial patterning of heterologous gene expression directly within the synthesized cellulose matrix.
