Article Abstract

, a key player in fermented food production, is known for generating pigments (MPs) and monacolin K (MK), possessing bioactive properties. However, the limited stability of MPs and mycotoxin citrinin (CTN) constrain the industry. Extremolytes like ectoine, derived from bacteria, exhibit cytoprotective potential. Here, we investigated the impact of ectoine on ATCC 16365, emphasizing development and secondary metabolism. Exogenous 5 mM ectoine supplementation substantially increased the yields of MPs and MK (105%-150%) and reduced CTN production. Ectoine influenced mycelial growth, spore development, and gene expression in . Remarkably, ectoine biosynthesis was achieved in , showing comparable effects to exogenous addition. Notably, endogenous ectoine effectively enhanced the stability of MPs under diverse stress conditions. Our findings propose an innovative strategy for augmenting the production and stability of bioactive compounds while reducing CTN levels, advancing the industry.

Ectoine, a natural bacterial osmolyte, suppressed UVA irradiated-α-melanocyte stimulating hormone (MSH) stimulated melanogenesis through antioxidant Nrf2 pathways in human keratinocytes; however, the underlying skin whitening mechanisms were not elucidated. The depigmenting efficiency of Ectoine (0-400 μM) through antimelanogenesis and melanin degradation by autophagy promotion was investigated in melanoma (B16F10) and melanin-feeding keratinocyte (HaCaT) cells and in vivo zebrafish model. MTT assay, Western blotting, GFP-LC3 puncta, AVO formation, melanin assay, immunofluorescence staining, TEM techniques, siLC3 transfection, and zebrafish model were utilized.

Ectoin attenuates cortisone-induced skin issues by suppression GR signaling and the UVB-induced overexpression of 11β-HSD1.

Background: Accelerated pace of modern work and lifestyles subject individuals to various external and psychological stressors, which, in turn, can trigger additional stress through visible signs of fatigue, hair loss, and obesity. As the primary stress hormone affecting skin health, cortisol connects to the glucocorticoid receptor (GR) to aggravate skin issues induced by stress. This activation depends on the expression of 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) in skin cells, which locally converts cortisone-produced by the central and peripheral hypothalamic-pituitary-adrenal axis-into its active form.

Unlabelled: OUT30018 is a moderately halophilic bacterium that synthesizes and accumulates ectoine as an osmolyte by activities of the enzymes encoded by the high salinity-inducible operon. Previously, we engineered a γ-aminobutyric acid (GABA)-producing GOP-Gad (Δ) from an ectoine-deficient mutant of this strain due to its ability to use high-salinity biomass waste as substrate. Here, to further increase GABA accumulation, we deleted which encodes GABA aminotransferase (GABA-AT) that catalyzes the first step of the GABA catabolic pathway, from the GOP-Gad genome.

The probiotic bacterium Nissle 1917 (EcN) holds significant promise for use in clinical and biological industries. However, the reliance on antibiotics to maintain plasmid-borne genes has overshadowed its benefits. In this study, we addressed this issue by engineering the endogenous cryptic plasmids pMUT1 and pMUT2.
