Summary: The flavor of Scotch malt whisky is greatly influenced by yeast strains, however, the specific relationship between yeast strain and flavor profile is still not entirely clear. Among 24 yeast strains tested, it was found that new make spirit produced using yeast strains marketed as 'brewing' strains was preferred in terms of acceptability rating.

Summary: This study examines the distribution of zinc at the subcellular level in different organs of rice and explores its accumulation mechanism in rice grains. It is found that the stem-sheaths are the main organs for zinc storage in rice, and the use of nitrogen fertilizer and zinc application enhances the transportation of zinc from vegetative organs to grains, thus increasing zinc accumulation in rice grains.

Summary: This study investigated the effects of nitrogen (N), zinc (Zn), and 24-epibrassionlide (EBL) alone and in combination on the growth and physiological characteristics of Cd and Zn in rice plants under Cd stress. The results showed that N and its combination with Zn or EBL promoted rice growth and yield, and the N + EBL treatment had the highest yield increase. In addition, the application of N, Zn, EBL, and their combined treatments reduced the Cd uptake in different parts of the rice plant and increased Cd distribution in cell walls, leading to decreased Cd concentration in grains.

Summary: This study examined the effects of different elicitors on biomass, camptothecin production, and antioxidant capacity of callus culture derived from Chonemorpha fragrans. The results showed that chitosan elicitation resulted in the highest biomass, while yeast extract elicitation led to higher camptothecin content. Additionally, elicitors could enhance the antioxidant capacity and secondary metabolite production in the callus culture.

Summary: Maintaining the balance of trace elements is crucial for organism health. Saccharomyces cerevisiae, as a widely used organism, can not only be used in various applications but also serve as a supplement for trace elements. Trace-element-enriched yeast, being more efficient, environmentally friendly, and safer than its counterparts, can provide a higher concentration of trace elements. Genetic engineering has the potential to further enhance the concentration of trace elements in yeast. This review explores different supplement forms of trace elements, mechanisms of detoxification and transport in yeast, as well as the feasibility, economy, safety, and future direction of trace-element-enriched yeast.

Summary: PARP-1 plays a crucial role in DNA repair pathways, and its activation is influenced by cellular zinc status. Depletion of zinc leads to DNA damage and genomic instability, while zinc overload triggers oxidative stress response in cells.

Summary: The trace element zinc plays a crucial role in regulating enzyme activity and metabolic processes in eukaryotic cells. Zinc deficiency has significant effects on development and has been linked to neurological disorders in the brain. This review highlights the importance of zinc during development, discusses the epidemiology and symptoms of zinc deficiency in humans, and provides an overview of different forms of zinc deficiency and the zinc transporters that control zinc balance.

Summary: Understanding the molecular characteristics and chemical transformations during yeast-yeast interactions is crucial. Non-targeted metabolomics was used to analyze the composition of grape must during sequential fermentation with non-Saccharomyces yeasts and Saccharomyces cerevisiae. The results showed that S yeasts dominate the fermentation process and lead to the formation of new compounds through reshuffling of yeast metabolism. Metabolomic analysis revealed significant changes in nitrogen metabolism due to yeast-yeast interactions.

Summary: The study showed that the addition of pharmacological levels of Zn can increase the average daily gain and feed intake of pigs without increasing bacterial resistance. There were no significant effects observed on growth, fecal dry matter, or antimicrobial resistance of fecal E. coli from live yeast and yeast extracts.

Summary: Yeast plays a crucial role in the production of beer. This study investigated the impact of rehydration of dry brewing yeast in specific conditions on the quality of beer. The results showed that rehydration with PTWAir accelerated the fermentation process and significantly altered the composition of volatile compounds in the finished beer, enhancing its aroma.

Summary: Cellular ageing is a multifactorial process at the molecular level, which leads to a variety of ageing trajectories. Recent discussions have focused on the decline of physicochemical homeostasis as a driver of aberrant phase transitions in the ageing process. Regardless of their participation in biomolecular condensates, all biological macromolecules function depends on parameters such as pH, crowding, and redox state. We further explore the hypothesis of physicochemical homeostasis and summarize recent evidence that the intracellular milieu influences molecular processes involved in ageing.

Summary: This study explores the transcriptome landscape of Rhodotorula mucilaginosa IIPL32, a red oleaginous yeast, during a two-stage fermentation process. It identifies key genes involved in fatty acid and terpenoid synthesis, with significantly higher expression in the nitrogen-limited stage. The study highlights enzymes such as diphosphomevalonate decarboxylase, acetylCoA-citrate lyase, and acetyl-CoA C-acetyltransferase as important in controlling metabolic flux, as well as acetoacetyl-CoA synthase, 3-ketoacyl-acyl carrier-protein reductase, and β-subunit enoyl reductase involved in lipid and terpenoid synthesis.
