Article Abstract
This research aimed to evaluate the diversity of yeasts recovered from fermented foods gathered from some areas of Northeastern Thailand. The fermented food items included Pla-som, Nham-pla, Kem-buknud, Isan-sausage, Pla-ra, Mhum-neu, Mhum-Khai-pla, Nham-neu, Nham-mu, Kung-joom, Som-pla-noi, and Poo-dong. Their probiotic characteristics were also investigated. A total of 103 yeast isolates of nine genera were identified using 28S rDNA sequencing. The yeast genera were (20.3%), (2.9%), (1.0%), (33.0%), (3.9%), (1.0%), (28.2%), (2.9%), and (6.8%). Based on probiotic characteristic analysis of ten selected yeast strains, KKKS4-1 showed the strongest probiotic characteristics in terms of hemolytic activity, antimicrobial activity against pathogenic bacteria, tolerance to low pH and bile salt and hydrophobicity. Isolated yeasts with probiotic characteristics may be useful in fermented food and animal feed production to improve their nutritional values.

Fungi are essential for a wide variety of food products and processes. They have a major role in the production of many fermented foodstuffs, may be eaten directly as fruit bodies and mycelium, and are used to produce food additives. They contribute to food production worldwide, even in cultures which do not typically consume mushrooms, because yeasts and edible moulds are utilised in a great variety of fermentation processes.

Precision fermentation represents an innovative cell-based production approach that employs synthetic biology and metabolic engineering tools, revolutionizing global food production by utilizing "microbial cell factories" to produce added-value ingredients. However, its global implementation is hindered by technological and scalability bottlenecks, regulatory fragmentation, regional accessibility and consumer acceptance, and nutritional trade-offs challenges. This review utilizes illustrated case studies and modeling analysis to present a detailed exploration of precision fermentation intersecting with global cell-based food production, discussing actionable research gaps and insights as well as advanced bioengineering practices and analytical techniques, to address these challenges for ongoing academic research, industrial applications and policy initiatives, thus supporting the transition of fermentation-enabled food production toward efficient and sustainable manufacturing.

Probiotics are live beneficial microorganisms that confer health benefits to the host when administered in adequate amounts, have gained considerable scientific and commercial interest for their ability to support gut health, strengthen immunity, and reduce disease risk. This review traces the genesis of probiotic science from its origins in traditional fermented foods to contemporary clinical applications, offering a conceptual understanding of its evolution. A clear distinction is drawn between endogenous probiotics, naturally resident in the human microbiome, and exogenous probiotics, introduced via dietary supplements and functional foods.

Hanseniaspora species are among the most prevalent yeasts found on grapes and other fruits, with a growing role in wine fermentation due to their distinctive metabolic profiles. This review focuses on the functional divergence within the genus, particularly between the fast-evolving fruit clade and the slow-evolving fermentation clade. While species in the fruit clade often exhibit limited fermentation capacity with interesting enzymatic activity, members of the fermentation clade-especially H.
