Modification of the glycolytic pathway in Pyrococcus furiosus and the implications for metabolic engineering
EXTREMOPHILES, 24(4), 511–518.
author keywords: Pyrococcus; Thermophile; Central metabolism; Glycolysis
MeSH headings : Fermentation; Glyceraldehyde 3-Phosphate; Glycolysis; Metabolic Engineering; Pyrococcus furiosus
TL;DR:
Insertion of a single gene encoding the thermostable NADPH-dependent primary alcohol dehydrogenase (adhA) from Caldanaerobacter subterraneus resulted in a strain producing ethanol via the previously established aldehyde oxidoreductase (AOR) pathway, and demonstrated a high ratio of ethanol over acetate at 80 °C and enabled ethanol production up to 85 °C, the highest temperature for bio-ethanol production reported to date.

Use of the lignocellulose-degrading bacterium Caldicellulosiruptor bescii to assess recalcitrance and conversion of wild-type and transgenic poplar
BIOTECHNOLOGY FOR BIOFUELS, 13(1).
author keywords: Caldicellulosiruptor; Extreme thermophiles; Lignocellulose; Biofuel; Poplar
TL;DR:
Utilizing C. bescii as a screening assay for recalcitrance, poplar lines with down-regulation of coumarate 3-hydroxylase 3 (C3H3) resulted in the highest degrees of solubilization and conversion by C. Bescii, suggesting that excellent digestibility can be achieved without compromising fitness of the tree.

Quantitative fermentation of unpretreated transgenic poplar by Caldicellulosiruptor bescii
NATURE COMMUNICATIONS, 10(1).
Contributors: n, P. Khatibi n, J. Wang n , J. Conway n, A. Williams-Rhaesa*, I. Peszlen n , V. Chiang n, M. Adams *, R. Kelly n
MeSH headings : Biomass; Cellulose / metabolism; Clostridiales / genetics; Clostridiales / metabolism; Ethanol / metabolism; Fermentation; Industrial Microbiology; Lignin / metabolism; Metabolic Engineering; Plants, Genetically Modified / chemistry; Plants, Genetically Modified / genetics; Plants, Genetically Modified / metabolism; Polysaccharides / metabolism; Populus / chemistry; Populus / genetics; Populus / metabolism
TL;DR:
The authors pair transgenic lignin modified poplar lines with engineered Caldicellusiruptor bescii to achieve biomass solubilization and ethanol conversion without pretreatment and the nearly quantitative microbial conversion of the carbohydrate content of unpretreated transgen lignocellulosic biomass bodes well for full utilization of renewable biomass feedstocks.

A synthetic enzymatic pathway for extremely thermophilic acetone production based on the unexpectedly thermostable acetoacetate decarboxylase from Clostridium acetobutylicum
BIOTECHNOLOGY AND BIOENGINEERING, 115(12), 2951–2961.

TL;DR:
A synthetic enzymatic pathway for acetone production that functions up to at least 70°C in vitro, made possible by the unusual thermostability of Adc from the mesophile C. acetobutylicum, paving the way for bio‐reactive distillation of acetone using a metabolically engineered extreme thermophile as a production host.
