Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

Development of a co‐culture of Ureibacillus thermosphaericus and Cupriavidus taiwanensis for inhibitors removal from hemicellulose prehydrolysate

Biotechnology Progress, EarlyView.
For biofuels production, hemicellulose pre‐hydrolysate is considered as an attractive feedstock rich in fermentable sugars. The pre‐hydrolysate derived from lignocellulosic biomass comprises, along with sugars, several inhibitors which can hamper its efficient conversion.

Furan- and Thiophene-2-Carbonyl Amino Acid Derivatives Activate Hypoxia-Inducible Factor via Inhibition of Factor Inhibiting Hypoxia-Inducible Factor-1

Molecules, 2018
Induction of a series of anti-hypoxic proteins protects cells during exposure to hypoxic conditions. Hypoxia-inducible factor-α (HIF-α) is a major transcription factor that orchestrates this protective effect.

Aromaticity‐Switchable Tetraoxa[8]circulenes as Anode Materials for Sodium‐Ion Batteries

ChemistryEurope, EarlyView.
Aromaticity‐based electrode materials have received substantial interest in recent years. Herein, a naphtho‐tetraoxa[8]circulene (N‐TOC) is introduced, its electrochemical performance is investigated, and its charge‐storage mechanism through aromaticity switching described by computational calculations.

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, EarlyView.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

Gold(I)‐Catalyzed Domino Cyclization for the Construction of Trispirocyclic Cyclohexanes

ChemistryEurope, EarlyView.
We describe herein a series of intricate trispirocyclic architectures that have been synthesized from readily available substrates through an operationally simple one‐pot transformation under mild conditions. An unprecedented gold(I)‐catalyzed domino cyclization involving 2‐ethynylbenzyl alcohol derivatives and heterocyclic α,β‐unsaturated imines ...

Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization

ChemistryEurope, EarlyView.
A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.
