Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 9, Page 7168-7190, September 2026.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

Probiotic Stability and Antihypertensive Activity of Peptides in Aguamiel Syrup‐Fortified Milk Protein Fermented by Lacticasebacillus rhamnosus GG

eFood, Volume 7, Issue 4, August 2026.
This study evaluates the impact of aguamiel syrup on a synbiotic fermented dairy product, focusing on antihypertensive peptide release and Lacticaseibacillus rhamnosus GG survival. While metabolic parameters remained unchanged, aguamiel syrup enhanced bioactive peptide production and antihypertensive activity (45.3%), suggesting its potential as a ...

Impact of Lactic Acid Bacteria Fermentation on the Nutritional and Sensory Quality of Arthrospira platensis Beverages

eFood, Volume 7, Issue 4, August 2026.
To improve the consumer appeal of Arthrospira platensis, this study utilized probiotic fermentation to mitigate its strong seaweed‐like aroma. Using Lactiplantibacillus plantarum significantly boosted amino acids, introduced novel volatiles, and enhanced umami flavors.

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

Frontiers 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.

Enhancing Probiotic Performance in Food Matrices: From Strain Selection to Bioengineering

Journal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT Probiotics are central to functional food innovation, but their application is limited by viability loss during processing, storage, and gastrointestinal (GI) transit. A key insight is that viability and functionality are distinct attributes; maintaining high cell counts does not guarantee that probiotics retain their beneficial properties ...

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

Plants
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

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

Structure-Based Design of Acetolactate Synthase From Bacillus licheniformis Improved Protein Stability Under Acidic Conditions

Frontiers in Microbiology, 2020
Catabolic acetolactate synthase (cALS) plays a crucial role in the quality of liquor because of its ability to catalyze the synthesis of the endogenous precursor product α-acetolactate of the aromatic compound tetramethylpyrazine (TTMP) and acetoin ...
