C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, Volume 16, Issue 7, Page 1314-1327, July 2026.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Simultaneous biosynthesis of (R)-acetoin and ethylene glycol from D-xylose through in vitro metabolic engineering

open access: yesMetabolic Engineering Communications, 2018
(R)-acetoin is a four-carbon platform compound used as the precursor for synthesizing novel optically active materials. Ethylene glycol (EG) is a large-volume two-carbon commodity chemical used as the anti-freezing agent and building-block molecule for ...

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.

Formate hydrogen lyase mediates stationary-phase deacidification and increases survival during sugar fermentation in acetoin-producing enterobacteria

open access: yesFrontiers in Microbiology, 2015
Two fermentation types exist in the Enterobacteriaceae family. Mixed-acid fermenters produce substantial amounts of lactate, formate, acetate and succinate, resulting in lethal medium acidification.

Fermented Plant‐Based Milks: A Review of Physicochemical and Technological Aspects to Sensory and Probiotic Attributes

open access: yesFood Bioengineering, Volume 5, Issue 2, Page 314-334, June 2026.
Technological and biotechnological processes, including fermentation with selected starter cultures, convert diverse plant raw materials into fermented plant‐based milks. These processes enhance nutritional profiles, functional and probiotic compounds, and improve physicochemical and sensory properties, supported by predictive modeling to optimize ...

Acetoin Promotes Plant Growth and Alleviates Saline Stress by Activating Metabolic Pathways in Lettuce Seedlings

open access: yesPlants
Acetoin is a volatile organic compound, which is a class of metabolites produced by plant growth-promoting rhizobacteria. The mechanisms underlying plant growth promotion by acetoin and its potential to induce saline stress tolerance in plants are poorly

Production and Multi‐Criteria Evaluation of Healthy White Cheese Snacks Using Microwave‐Vacuum Drying

open access: yesJournal of Food Science, Volume 91, Issue 6, June 2026.
ABSTRACT Microwave‐assisted vacuum drying (MVD) is an emerging technology suitable for producing healthy snack foods, such as cheese snacks. This study aimed to produce a low‐fat, low‐salt, crunchy cheese snack using MVD. Low‐fat, low‐salt cheese slices were dried under seven different combinations of microwave power (5%–15%), vacuum level (220–300 ...

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

open access: yesBiotechnology 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
