Redox-balance-based growth coupling links oxidoreductase activity to cellular fitness and can enable high-throughput enzyme selection and strain evolution. However, because growth reflects the fitness of the whole cell, metabolic adaptation can circumvent the intended selective pressure. Here, we investigated the evolu...

Engineering robust fermentation hosts remains a barrier to scalable biomanufacturing. In this work we replace canonical mixed-acid fermentation in
Escherichia coli
with a redox‑balanced reverse β‑oxidation (rBOX) pathway that produces medium‑chain fatty alcohols and is bioenergetically equivalent to ethanol ferme...

Advances in metabolic engineering have enabled the integration of diverse non-native reactions into microbial hosts, providing sustainable alternatives to petrochemical manufacturing. We previously developed a modular polyketide synthase (PKS)-based platform in Streptomyces albus for producing 17 diols, amino alcohols,...

Acetate is an attractive renewable two-carbon substrate for microbial biotechnology, but its toxicity limits growth and carbon-use efficiency at process-relevant concentrations. Here, we used adaptive laboratory evolution to improve acetate tolerance in a genome-reduced strain of Pseudomonas putida and combined whole-g...

Efficient co-utilization of hexose and pentose sugars from lignocellulose is essential for microbial bioconversion, yet engineered catabolic pathways can be unstable or suboptimal in complex resource environments. Here, we use a Pseudomonas putida strain engineered to catabolize xylose and arabinose to examine how reso...
