The biosynthesis of microbial secondary metabolites is induced by a wide range environmental stresses. In this study, submerged fermentation Monascus yellow pigments ruber CGMCC 10910 under high glucose stress was investigated. increase lipid content the major contributor to dry cell weight (DCW), and lipid-free DCW only slightly changed stress, which benefited accumulation intracellular hydrophobic pigments. fatty acid composition analysis in membranes showed that significantly increased...
Monascus pigments are widely used in the food and pharmaceutical industries due to their safety human health. Our previous study found that glucose concentration induced extracellular oxidoreduction potential (ORP) changes could influence water-soluble yellow pigment production by ruber CGMCC 10910 submerged fermentation. In this study, H2O2 dithiothreitol (DTT) were change for investigating effects of oxidative or reductive substances on 10910. The ORP be controlled DTT. Both cell growth...
Monitoring the cable terminal's partial discharge (PD) is of great significance to ensure line's safe and stable operation. To improve anti-interference ability real-time performance detection, this paper develops a Mach-Zehnder interferometer (MZI) detection system for cross-linked polyethylene (XLPE) terminals. The optical fiber implanted into 10 kV XLPE terminal, airgap defects different volumes are set in main insulation. inside terminal serves as sensing head MZI signal arm. PD test was...
Hydrodistilled essential oils (EO) of Psidium guajava L. leaves from different regions in China were analyzed by GC and GC/MS. The samples Guangdong Province displayed high EO yields (0.61 - 0.75%, v/w). A total 50 components, representing over 98.00% the EOs, identified semi-quantitatived. major constituents EOs included β-caryophyllene (17.17 31.38%), γ-gurjunene (9.17 15.22%), τ-cadinol (1.35 10.02%) calamenene (2.13 7.80%). terpenoids all sample dominated sesquiterpenes hydrocarbons...
Monascus species can produce secondary metabolites that have a polyketide structure. In this study, four types of extracellular water-soluble yellow pigments (Y1-Y4) were generated by submerged fermentation with ruber CGMCC 10910, which Y3 and Y4 had strong fluorescence. The composition the pigment mixtures was closely related to temperature. dominating changed from Y1 when temperature increased 30 35 °C. Increasing °C metabolic pathways pigments, inhibited biosynthesis enhanced Y4....
Traditional submerged fermentation mainly accumulates intracellular orange pigments with absorption maxima at 470 nm, whereas extractive of Monascus spp. Triton X-100 can promote the export to extracellular broth, obtaining yellow approximately 410 nm. In this study, a strain (M. anka GIM 3.592) that produces high yields was employed investigate differences in pigment fingerprint profiles between and fermentations.Using high-yield strain, exhibited an maximum 430 not as previously observed....
