Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.

Supercritical Carbon Dioxide and Its Potential as a Life-Sustaining Solvent in a Planetary Environment

Life, 2014
Supercritical fluids have different properties compared to regular fluids and could play a role as life-sustaining solvents on other worlds. Even on Earth, some bacterial species have been shown to be tolerant to supercritical fluids.

Whole‐Cell Production of Resolvin E2 and 17R‐Resolvin D5 by a Double‐Oxygenating 15S‐Lipoxygenase With 5S‐Lipoxygenase Activity From Pseudobdellovibrionaceae bacterium

Biotechnology and Bioengineering, EarlyView.
A recombinant whole‐cell platform expressing a bacterial 15S‐LOX exhibiting 5S‐LOX activity enabled the stereoselective production of RvE2 and 17R‐RvD5 from 18R‐HEPE and 17R‐HDHA, achieving final concentrations of 0.57 mM and 1.48 mM from 4.0 mM substrates, respectively, under optimized conditions.

Immobilization of Alginate Microbeads With Whole‐Cells Expressing Nitrilase for Continuous Nicotinic Acid Production in Chip Millireactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The biocatalytic production of nicotinic acid using nitrilases has emerged as a promising alternative to conventional chemical synthesis, offering improved selectivity and environmental sustainability. In this study, we developed a continuous‐flow millireactor system employing Escherichia coli cells expressing a nitrilase from Paraburkholderia

Scalable catalyst production process for oleate hydratase whole‐cell biocatalysis

Biotechnology Progress, EarlyView.
This study establishes a scalable lactose‐induced fed‐batch fermentation for an Escherichia coli whole‐cell biocatalyst containing an oleate hydratase. Operation at a higher growth rate markedly increased biomass yields while maintaining catalyst activity and was demonstrated at 150 L scale.

Phenolic‐Associated Dietary Fiber Ingredients From Agro‐Industrial Residues: Processing‐Dependent Identity and Food‐Grade Translation

ChemFoodChem, EarlyView.
Agro‐industrial residues contain dietary fiber and phenolics, but coexistence alone does not establish a phenolic‐bound ingredient. Processing‐dependent identity is verified through fraction‐specific analysis and common‐basis mass balance. Food‐grade translation requires final‐product performance, sensory acceptance, safety, and claim‐matched ...
