Integrative analysis of transcriptome and metabolome profiling uncovers underlying mechanisms of the enhancement of the synthesis of biofilm in Sporobolomyces pararoseus NGR under acidic conditions

Microbial Cell Factories, Journal Year: 2025, Volume and Issue: 24(1)

Published: Jan. 7, 2025

Sporobolomyces pararoseus is a well-studied oleaginous red yeast that can synthesize variety of high value-added bioactive compounds. Biofilm one the important biological barriers for microbial cells to resist environmental stresses and maintain stable fermentation process. Here, effect acidic conditions on biosynthesis biofilms in S. NGR was investigated through combination morphology, biochemistry, multi-omics approaches. The results showed environment key factor trigger biofilm formation NGR. When cultured under pH 4.7, colony morphology wrinkled, were wrapped by large amount extracellular matrix, hydrophobicity anti-oxidative stress ability significantly improved, yield intracellular carotenoids increased. Transcriptome metabolome profiling indicated carbohydrate metabolism, amino acid lipid nucleic metabolism enriched 4.7 culture conditions, including 56 differentially expressed genes 341 differential metabolites. These metabolites may play an role response stress. will provide strategies development utilization beneficial biofilms, theoretical support industrial production microorganisms improve their resistance growth.

Antimicrobial Activity of the Peptide C14R Against Ab Initio Growing and Preformed Biofilms of Candida albicans, Candidaparapsilosis and Candidozyma auris

Biomolecules, Journal Year: 2025, Volume and Issue: 15(3), P. 322 - 322

Published: Feb. 21, 2025

Biofilms are the predominant lifeforms of microorganisms, contributing to over 80% infections, including those caused by Candida species like C. albicans, parapsilosis and Candidozyma auris. These form biofilms on medical devices, making infections challenging treat, especially with rise in drug-resistant strains. particularly hospital-acquired ones, a significant health threat due their resistance antifungals risk developing systemic (i.e., sepsis). We have previously shown that C14R reduces viability albicans auris, but not parapsilosis. Here, we show only inhibits pore formation, resazurin reduction assay, fluorescence-based permeabilization it also halts biofilm maturation significantly biomass preformed 70%. findings suggest could be an effective option for treating severe fungal offering potential new treatment approach biofilm-related diseases. Further research is needed fully understand its dispersal optimize use future applications as antifungal clinical settings.

Weight loss is a hallmark of many infections, including those caused by bacteria, fungi and parasites. This often attributed to infection-induced anorexia the need mobilise energy from internal sources cope with pathogens. during infection results significant reduction muscle fat mass, two organs that together account for approximately 60% body mass in healthy state. While wasting well-documented aspect infection-related weight loss, adipose tissue via lipolysis also plays critical role can determine disease outcomes. review explores regulators depletion excessive infection, probable mechanisms, potential consequences host survival pathogen fitness.
