According to the results of the single temperature on Monascus anka mutant growth and monascus yellow pigments production in this paper, two stages in the fermentation temperature control strategy has been operated as following: the temperature was 34°C to improve the Monascus growth before culture 48 hour and then 32°C was carried out to improve theItalic text yellow pigments production. The results demonstrated that two stages temperature control at 96 hours, the yield of monascus yellow pigments can arrive 164.51 OD units, it was 180.35%, 2165.48%, 107.66%, 5.76%, 33.23%, 36.74% higher than that of 26°C, 28°C, 30°C, 32°C, 34°C, 36°C fermentation, respectively. The maximum specific growth rate(µ) and the maximum specific production rate of yellow pigments( qy) could arrive 0.0528 h-1 and 0.404 OD.g-1.h-1, and it was 5.30% and 3.22% higher than that of 34°C and 32°C, respectively. The specific production rate of yellow pigments was varied from 0.2 OD.g-1.h-1 to 0.4 OD.g-1.h-1 in whole fermentation. Two stage temperature control strategy could improve the yellow pigments production, increase µ and and short the culture time.

Graphical AbstractMonascus yellow pigments (MYPs) in functional Qu (FQ) have a higher antioxidant potential than those in coloring Qu (CQ). The difference in antioxidant activities of MYPs is due to the critical hydroxyl group on C-3′ or C-11.

Pigment content of ashes grown up under different circumstances - The pigment content (chlorophyll a, chlorophyll b,  xanthophyll and carotene) has been researched with ashes grown up under  different light circumstances and varying in age and height.     The results prove that the general laws concerning the influence of light  on the pigment content, don’t always work.     The phenomen is very complex. The light quantity is very important in some  cases, but insignificant in others. It seems origin and height of plants have  a strong influence. The results prove also the influence of the environment  is much higher on small plants as on big ones.     The research indicates finally the correlation between the green pigments,  the yellow pigments, and between the green pigments on the one side and the  yellow ones on the other side.

Abstract Disazoacetoacetanilide pigments, more commonly known as diarylide yellows, are the most important group of yellow classical organic pigments. They were commercialized in the early 20th century many years after the introduction of the structurally related monazoacetoacetanilides (Hansa yellows). The molecules adopt the bis-ketohydrazone tautomeric form. X-ray single crystal structure investigations have provided an insight into the influence of the molecular geometry and crystal packing arrangements in the solid state on the properties of the pigments in application. The synthesis of diarylide pigments is relatively straightforward, the conditions essentially following those used for the corresponding monoazo pigments, so that the products are economically priced. In the case of these disazo pigments, suitable aromatic amines (1 mol) are bis-diazotized and the resulting bis-diazonium salts reacted with acetoacetanilide coupling components (2 mol), the two azo coupling reactions occurring at the same time. They are by far the dominant group of yellow pigments used in printing inks, well-suited for most standard process yellow inks. They were formerly important in the coloration of plastics but are no longer recommended for polymers processed above 200 °C, under which conditions toxic decomposition products are formed. Diarylide yellow pigments are characterized by high color strength, good to excellent solvent fastness, and good chemical stability, although they generally show inferior lightfastness.
