Pigment fingerprint profile during extractive fermentation with Monascus anka GIM 3.592
BACKGROUND Traditional submerged fermentation mainly accumulates intracellular orange pigments with absorption maxima at 470 nm, whereas extractive fermentation of Monascus spp. with Triton X-100 can promote the export of intracellular pigments to extracellular broth, mainly obtaining extracellular yellow pigments with absorption maxima at approximately 410 nm. In this study, a strain of Monasc...
متن کاملTracking of pigment accumulation and secretion in extractive fermentation of Monascus anka GIM 3.592
BACKGROUND Monascus pigments are promising sources for food and medicine due to their natural food-coloring functions and pharmaceutical values. The innovative technology of extractive fermentation is used to promote pigment productivity, but reports of pigment trans-membrane secretion mechanism are rare. In this study, tracking of pigment accumulation and secretion in extractive fermentation o...
متن کاملThe pigment characteristics and productivity shifting in high cell density culture of Monascus anka mycelia
BACKGROUND Monascus mycelia and pigments are promising sources of food and medicine with their potential pharmaceutical values and health-improving functions. Using high cell density fermentation of Monascus spp. to achieve higher mycelium and yellow pigment production is worthy to be researched. In this study, the characteristics and productivity shifting of pigments in high cell density cultu...
متن کاملMonascus pigment production by solid-state fermentation with corn cob substrate.
Natural pigments are an important alternative to potentially harmful synthetic dyes. We investigated the feasibility of corn cob powder as a substrate for production of pigments by Monascus purpureus KACC 42430 in solid-state fermentation. A pigment yield of 25.42 OD Units/gram of dry fermented substrate was achieved with corn cob powder and optimized process parameters, including 60% (w/w) ini...
متن کاملAnalyses of Monascus pigment secretion and cellular morphology in non‐ionic surfactant micelle aqueous solution
Monascus pigments produced by Monascus spp. are widely used as natural food colourants. Extractive fermentation technology can facilitate the secretion of intracellular Monascus pigments into extracellular non-ionic surfactant micelle aqueous solution, so as to avoid the feedback inhibition and decomposition. In this study, behaviour of the trans-membrane secretion of Monascus pigments was inve...
