Antimicrobial activities of amino acid derivatives of monascus pigments.
Amino acid derivatives of monascus pigments were produced by fermentation, and their antimicrobial activities were determined. Thirty-nine l- and d-forms of amino acids were added as a precursor to the fermentation medium for derivation of pigments. Derivatives with L-Phe, D-Phe, L-Tyr, and D-Tyr exhibited high activities against Gram(+) and Gram(-) bacteria with MIC values of c. 4-8 microg mL(...
متن کاملPigments and citrinin biosynthesis by fungi belonging to genus Monascus.
Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...
متن کاملAssessment of the dyeing properties of pigments from Monascus purpureus
Monascus purpureus C322 was cultivated on well-established production media to yield prevailingly red or orange pigment-rich ethanolic extracts. Once these extracts had been diluted by an overall factor of 50, they were used as such to dye raw wool standard specimens differently premordanted using alum or stannic chloride. Independently of the mordant used, the specimens dyed with the red pigme...
متن کاملLv. Studies on Bile Pigments
THE study of bile pigment derivatives is important because these substances represent the end-products of haemoglobin metabolism. The destruction of haemoglobin both normal and pathological can thus be measured by quantitative determination of the urobilin and urobilinogen in urine and faeces. On the other hand, when pathological destruction of haemoglobin can be excluded, urobilinor urobilinog...
متن کاملEffect of media composition on citrinin and bio-pigments production by Monascus ruber
Article history: Received on: 06/12/2016 Accepted on: 19/01/2017 Available online: 20/03/2017 Monascus species are used for production of red bio-pigments, which are used as food coloring agents. However, presence of the mycotoxin citrinin, which is a secondary metabolite produced in conjunction with the red pigments, prevents the use of these pigments in large scale. In the present study, Mona...
