Yeast and its derivatives, including yeast extract and yeast cell wall, are well established as safe and environmentally sustainable feed additives that significantly improve animal production performance and health. Their incorporation into swine production serves as an innovative nutritional strategy aimed at improving growth performance, bolstering health status, and enhancing immune function in pigs. As a versatile microorganism, yeast generates a variety of bioactive compounds through fermentation, such as amino acids, vitamins, enzymes, and growth factors, which collectively contribute to improved growth and overall health in pigs. This review consolidates current research on the utilization of yeast and yeast derivatives in swine production, highlighting their biological functions and practical implications within the industry.

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.

Lipophilic yeasts of the genus are commensal fungi that constitute the normal skin microbiota but may become pathogenic. These fungi, especially , convert tryptophan into various alkaloid indoles such as malassezione, which may serve as virulence factors. To facilitate testing of malassezione as an aryl hydrocarbon receptor agonist and potential glucokinase activator, we developed a convenient synthetic route from commercially available indole-3-acetic acid.

We have developed the methylotrophic yeast Ogataea minuta as a useful host for producing heterologous proteins. In this study, a double mutant that lacks the Prb1 protease and alcohol oxidase was generated and applied for heterologous protein production. Upon our optimization of the fermentation conditions, such as feeding of carbon and nitrogen sources and pH control, this mutant showed increased production of human serum albumin, resulting in a yield of approximately 7.

The biting midges, Culicoides peregrinus Kieffer and Culicoides oxystoma Kieffer (Diptera: Ceratopogonidae) are the most significant vector species of bluetongue virus (BTV) in the Oriental region, including India. Rearing of these vector species was cumbersome; previous researchers supplemented the rearing substrates primarily with cattle dung (the habitat), yeast and nutrient broth. Other investigations reiterated that an enriched milieu of live bacteria is required for the oviposition and developmental progression of the immatures as they failed to develop in sterile medium.

Domiati cheese, one of the most popular soft white cheeses, is particularly susceptible to microbial deterioration due to its high moisture content and low salt concentration. This study assesses the effectiveness of a new edible coating made from carboxymethyl chitosan nanoparticles loaded with pomegranate peel extract (CCS LP) in increasing the shelf life of Domiati cheese. The study compares CCS LP's performance to pomegranate peel extract (PPE) and carboxymethyl chitosan nanoparticles (CCS NPs) alone.
