Lactic acid bacterium F. sanfranciscensis impairs fitness of yeast M. humilis in a synthetic wheat sourdough medium

Anna Elizabeth Wittwer, Diego Segond, Thèrése Marlin, Céline Serre et autres

ABSTRACT Sourdough starters contain simple microbial communities, typically consisting of a few bacterial species and one or two yeast species. The yeast Maudiozyma humilis and the lactic acid bacterium Fructilactobacillus sanfranciscensis often co-occur in sourdough starters and have been presumed to exist …

Simplifying complex microbial communities for food and beverage fermentations

Kate Howell

Fermentation of foods and beverages has occurred in human societies for many thousands of years. In our modern world, food systems have dramatically changed and as our understanding of microbiology progressed, food production has shifted to using defined fermentations, inoculated by single …

Phenolic-rich blueberry extract enhances gentamicin efficacy against multidrug-resistant Acinetobacter baumannii BAA1605 via efflux inhibition and suppression of antibiotic-induced metabolic activation

Ze Liang, Zijian Liang, Hang-Wei Hu, Kate Howell et autres

The growing threat of antibiotic resistance calls for novel strategies to enhance antimicrobial efficacy. Blueberries, rich in phenolic compounds, have attracted attention as food-derived agents capable of modulating bacterial resistance mechanisms. This study explores the potential of phenolic-rich blueberry extracts as antibiotic …

Solvent dielectric constant as a predictor of polyphenol yield and antioxidant activity in extracts from moringa

Dillani Putri Ramadhaningtyas, Jamie Selby‐Pham, Kate Howell, Sophie N.B. Selby-Pham

Polyphenol extraction is strongly influenced by solvent characteristics. This study investigated the effect of solvent dielectric constant on polyphenols recovery and antioxidant activity, using ultrasound-assisted extraction of moringa as a model system. Solvent mixtures of methanol, ethanol, and acetone with water were …

Digital image analysis to assess the texture of bread products

Michael Ruderman, Kate Howell, R. Appels

• MATLAB-based Bread Texture Analyser quantifies bread texture non-destructively. • Digital ‘texture-fingerprints’ objectively assess bread quality and uniformity. • Applied to five breads, capturing unique porosity, density, and cell distribution. • Digital analysis validated against sensory evaluation for perceived bread quality. • …

Tibicos differentially affects faecal microbiota composition and short-chain fatty acid production in prediabetic and healthy adults in a simulated digestive tract

Miin Chan, Xinwei Ruan, Liz Leya Ninu, Jing Wang et autres

Prediabetes and obesity are increasingly prevalent chronic pro-inflammatory conditions driven by gut microbiota dysfunction. To assist in the management of such diseases, researchers are interested in gut-microbiota targeted dietary interventions. Tibicos is a plant-based fermented beverage shown to modulate gut microbiota, with …

Food substances alter gut resistome: Mechanisms, health impacts, and food components

Ze Liang, Zijian Liang, Hang‐Wei Hu, Kate Howell et autres

Antibiotics are effective in treating bacterial infections, but their widespread use has spurred antibiotic resistance, which is linked closely with human disease. While dietary components are known to influence the gut microbiome, specific effects on the gut resistome-the collection of antibiotic-resistant genes …
