Abstract

Alleviating our society's dependence on petroleum-based chemicals has been highly emphasized due to fossil fuel shortages and increasing greenhouse gas emissions. Isopropanol is a molecule of high potential to replace some petroleum-based chemicals, which can be produced through biological platforms from renewable waste carbon streams such as carbohydrates, fatty acids, or CO2. In this study, for the first time, the heterologous expression of engineered isopropanol pathways were evaluated in a Cupriavidus necator strain Re2133, which was incapable of producing poly-3-hydroxybutyrate [P(3HB)]. These synthetic production pathways were rationally designed through codon optimization, gene placement, and gene dosage in order to efficiently divert carbon flow from P(3HB) precursors toward isopropanol. Among the constructed pathways, Re2133/pEG7c overexpressing native C. necator genes encoding a β-ketothiolase, a CoA-transferase, and codon-optimized Clostridium genes encoding an acetoacetate decarboxylase and an alcohol dehydrogenase produced up to 3.44 g l(-1) isopropanol in batch culture, from fructose as a sole carbon source, with only 0.82 g l(-1) of biomass. The intrinsic performance of this strain (maximum specific production rate 0.093 g g(-1) h(-1), yield 0.32 Cmole Cmole(-1)) corresponded to more than 60 % of the respective theoretical performance. Moreover, the overall isopropanol production yield (0.24 Cmole Cmole(-1)) and the overall specific productivity (0.044 g g(-1) h(-1)) were higher than the values reported in the literature to date for heterologously engineered isopropanol production strains in batch culture. Strain Re2133/pEG7c presents good potential for scale-up production of isopropanol from various substrates in high cell density cultures.

Attention Score in Context

This research output has an Altmetric Attention Score of 17. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 December 2019.
All research outputs
#1,159,023
of 15,306,144 outputs
Outputs from Applied Microbiology & Biotechnology
#65
of 6,216 outputs
Outputs of similar age
#24,125
of 288,875 outputs
Outputs of similar age from Applied Microbiology & Biotechnology
#2
of 131 outputs
Altmetric has tracked 15,306,144 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 6,216 research outputs from this source. They receive a mean Attention Score of 3.7. This one has done particularly well, scoring higher than 98% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 288,875 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 91% of its contemporaries.
We're also able to compare this research output to 131 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 98% of its contemporaries.
