TL;DR: Four non-native metabolic reactions are used to rewire central carbon metabolism in S. cerevisiae, enabling biosynthesis of cytosolic acetyl coenzyme A (acetyl-CoA, the two-carbon isoprenoid precursor) with a reduced ATP requirement, reduced loss of carbon to CO2-emitting reactions, and improved pathway redox balance.

TL;DR: One potential conversion process to hydrocarbon products by way of biological conversion of lingnocellulosic-dervied sugars was described in this paper, which converted biomass to a hydrocarbon intermediate, a free fatty acid, using dilute-acid pretreatement, enzymatic saccharification, and bioconversion.

Nitrous oxide generation in full-scale biological nutrient removal wastewater treatment plants
TL;DR: N(2)O formation was shown to be always positive, yet highly variable across the seven full-scale BNR wastewater treatment plants (WWTP), but with many competing and parallel nitrogen transformation reactions occurring, it was very difficult to clearly identify the predominant mechanism of N( 2)O production.
