Enabling Production of Algal Biofuels by Techno-Economic Optimization of Co-Product Suites

Frontiers in Chemical Engineering, 2022
Recent techno-economic analysis (TEA) has underscored that for algal biofuels to be cost competitive with petroleum fuels, co-products are necessary to offset the cost of fuel production.

Sourcing thermotolerant poly(ethylene terephthalate) hydrolase scaffolds from natural diversity

Nature Communications, 2022
Enzymes have potential for recycling plastics such as PET, a polyester used in textiles and single-use packaging. Here, the authors identify and characterize additional PET-active biocatalysts and expand the number and diversity of thermotolerant ...

Catalytic carbon–carbon bond cleavage in lignin via manganese–zirconium-mediated autoxidation

Nature Communications
Efforts to produce aromatic monomers through catalytic lignin depolymerization have historically focused on aryl–ether bond cleavage. A large fraction of aromatic monomers in lignin, however, are linked by various carbon–carbon (C–C) bonds that are more ...
