Title: Study on technical conditions and characteristics of pigments by Monascus anka 5040
Abstract:The fermentation conditions of Monascus anka 5040 was optimized to produce monascus pigments;And the change regulation of colour values by Monascus anka 5040 in submerged culture and the distribution ...The fermentation conditions of Monascus anka 5040 was optimized to produce monascus pigments;And the change regulation of colour values by Monascus anka 5040 in submerged culture and the distribution of red and yellow pigments in monascus pigments were studied.The results showed that:(① The) optimum fermentation conditions of Monascus anka 5040 were 170 r/min table rotational speed,(32 ℃) temperature,pH5.4 and 90 mL/L load.② There were three phases in the fermentation course:a lot of the Monascus anka grew in the 0-32 h of fermentation,and the pigments were produced stably and largely in the 32-128 h,the Monascus anka and the pigments were reduced after 128 h;the pigments were produced stably in the 0-128 h of fermentation.③ The content of red pigments inside cells were more than that outside cells.There was no regulation about the distribution of yellow pigments inside and outside cells,and the contents of yellow pigments were more than that of red ones,the liquid appeared yellow.Read More
