Optimization of Medium Composition and Fluidized Bed Drying Conditions for Efficient Production of Dry Yeast.

Yeast formulations such as dry yeast are essential for supplying microbial starters to the alcoholic beverage industry. In Korea, the expensive freeze-drying method is used to manufacture brewer's dry yeast, and therefore an economical process such as fluidized bed drying is needed. In the dry yeast manufacturing process, the medium and drying conditions are key factors that determine its quality and manufacturing cost.

Investigation of Microbial Community of Korean Soy Sauce () Using Shotgun Metagenomic Sequencing and Its Relationship with Sensory Characteristics.

The microbial community of a soy sauce is one of the most important factors in determining the sensory characteristics of that soy sauce. In this study, the microbial communities and sensory characteristics of twenty samples of Korean soy sauce () were investigated using shotgun metagenome sequencing and descriptive sensory analysis, and their correlations were explored by partial least square (PLS) regression analysis. The metagenome analysis identified 1332 species of bacteria, yeasts, molds, and viruses across 278 genera, of which , , and accounted for more than 80% of the total community.

A recent large-scale intraspecific IR expansion and evolutionary dynamics of the plastome of Peucedanum japonicum.

Peucedanum japonicum (PJ), a member of the Apiaceae family, is widely distributed and cultivated in East Asian countries for edible and functional foods. In this study, we compared the plastid genomes (plastomes) and 45S nuclear ribosomal DNA (45S nrDNA) simultaneously from 10 PJ collections. Plastome-based phylogenetic analysis showed that the PJ accessions were monophyletic within the genus Peucedanum.

Rectal Administration of Propylthiouracil in a Critically Ill Patient: A Life-Saving Experience.

Hyperthyroidism is a common endocrine disease caused by the production of thyroid hormones in excessive amounts. Propylthiouracil (PTU) is one of the anti-thyroid drugs (ATD) used in the treatment of hyperthyroidism. Rectal PTU should be considered by physicians as a valuable option for managing hyperthyroidism as an alternative route of administration for patients who cannot tolerate oral medications.

Prophylactic phage aerosols for nosocomial infection control in an extracorporeal membrane oxygenation unit: A 4-year prospective study of temporospatially designed phage cocktails.

Phage-based decontamination has rarely been explored in real-world settings, particularly in the environments of patients undergoing extracorporeal membrane oxygenation (ECMO). This four-year prospective study aimed to evaluate the effectiveness of aerosolized phage cocktails tailored to combat target antibiotic-resistant species of Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia. The decontamination procedure with phage aerosols was proactively implemented before the admission of ECMO patients based on a thorough analysis of phage typing results from bacterial species isolated from prospective patient areas during the preceding two months.
