Esters of (S)-1,2-propanediol and (R,R)-2,3-butanediol — Chiral Compounds Inducing Cholesteric Phases with a Helix Inversion · [PDF]

, 1987
Mesogenic chiral esters of optically active (S)-1,2-propanediol and (R,R)-2,3-butanediol were synthesized. The compounds, added to a nematic phase induce cholesteric phases exhibiting a helix inversion with temperature variation.

Stabilizing Plasmodium falciparum proteins for small molecule drug discovery

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Early‐stage drug discovery relies on the availability of stable protein for reliable biophysical characterization of ligand binding. However, many Plasmodium falciparum proteins are challenging to produce in heterologous systems, which limits their experimental utility.

Separating 2,3-butanediol from fermentation broth using n-butylaldehyde

Journal of Saudi Chemical Society, 2016
In this paper, a complete separation process for 2,3-butanediol fermentation broth has been developed using reactive-extraction and reactive-distillation. n-Butylaldehyde can be used as both reactant and extractant in the process.

Microbial Community Shifts and Plant Performance Improvements Driven by Bacillus firmus in Pampa Agroecosystems

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
The study shows that Bacillus firmus‐based bionematicides modulate soil microbiota and enhance soybean growth in the Pampa biome. Effects vary by location and time, with increased beneficial bacteria, reduced fungi, and decreased root nematode infestation. Overall, B.

Sustainable Syntheses of p‐Hydroxycinnamic‐Based Macrobisphenols: Progress, Challenges, and Comparative Assessment of Yield and Sustainability

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
The strengths and limitations of sustainable routes to macrobisphenols — safe‐by‐design biomass‐derived bisphenols — were critically evaluated to support informed selection based on sustainability metrics (EcoScale, E‐factor), efficiency, cost, and scalability.

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Thermophilic fermentation of acetoin and 2,3-butanediol by a novel Geobacillus strain

Biotechnology for Biofuels, 2012
Background Acetoin and 2,3-butanediol are two important biorefinery platform chemicals. They are currently fermented below 40°C using mesophilic strains, but the processes often suffer from bacterial contamination. Results This work reports the isolation

Unlocking the Quality Potential of Liberoid Coffee: Advances in Composition, Processing, and Microbial Fermentation

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Liberoid coffee (Coffea liberica group), comprising varieties of Liberica and Excelsa coffee types, is gaining attention for its unique chemical composition and sensory potential. However, its quality remains under‐optimized due to limited understanding of genotype‐specific traits and processing responses.
