Lipases are important biocatalysts and ubiquitous in plants, animals, and microorganisms. The high growth rates of microorganisms with low production costs have enabled the wide application of microbial lipases in detergent, food, and cosmetic industries. Herein, a novel lipase from Lacticaseibacillus rhamnosus IDCC 3201 (Lac-Rh) was isolated and its activity analyzed under a range of reaction conditions to evaluate its potential industrial application. The isolated Lac-Rh showed a molecular weight of 24 kDa and a maximum activity of 3438.5 ± 1.8 U/mg protein at 60 °C and pH 8. Additionally, Lac-Rh retained activity in alkaline conditions and in 10% v/v concentrations of organic solvents, including glycerol and acetone. Interestingly, after pre-incubation in the presence of multiple commercial detergents, Lac-Rh maintained over 80% of its activity and the stains from cotton were successfully removed under a simulated laundry setting. Overall, the purified lipase from L. rhamnosus IDCC 3201 has potential for use as a detergent in industrial applications. KEY POINTS: • A novel lipase (Lac-Rh) was isolated from Lacticaseibacillus rhamnosus IDCC 3201 • Purified Lac-Rh exhibited its highest activity at a temperature of 60 °C and a pH of 8, respectively • Lac-Rh remains stable in commercial laundry detergent and enhances washing performance.

Irritable bowel syndrome is a chronic disorder affecting the gastrointestinal tract, negatively impacting patients' quality of life. Here, we aimed to evaluate the effects of Lacticaseibacillus rhamnosus IDCC 3201 (RH 3201) on irritable bowel syndrome with constipation (IBS-C). In this randomised, double-blind, placebo-controlled trial, a total of 30 subjects with IBS-C were randomly assigned (1:1) to receive 8 weeks of probiotics administration or placebo.

Article Synopsis
- The study investigates the probiotic potential of candidate IDCC 3201 by using a surrogate animal model to analyze how well it adheres to the gastrointestinal tract compared to standard probiotics.
- Findings show that IDCC 3201 has greater adhesive capabilities and significantly improves lifespan, as well as enhances immune responses to foodborne pathogens when preconditioned.
- Multi-omics analysis indicates that feeding IDCC 3201 increases important immune-related gene expression and levels of beneficial metabolites like lactic acid, supporting its effectiveness as a probiotic.

This study aimed to explore the safety and properties of IDCC 3401 as a novel probiotic strain via genomic and phenotypic analyses. In whole-genome sequencing, the genes associated with antibiotic resistance and virulence were not detected in this strain. The minimum inhibitory concentration test revealed that IDCC 3401 was susceptible to all the antibiotics tested, except for kanamycin.

Background: Due to the recency of the postbiotic field, no head-to-head postbiotic studies have investigated its biotherapeutic potential for atopic dermatitis (AD). No network meta-analysis (NMA) has been conducted to synthesize relevant studies comparing postbiotic interventions for AD.
Objective: To assess the comparative efficacy and safety of postbiotic strains in the treatment of pediatric AD.
