13. Production of red pigments by Monascus ruber in culture media containing corn steep liquor
The production of red pigments by Monascus ruber was evaluated utilizing complex culture media composed of glucose or sucrose (10 g/L), corn steep liquor (5 or 10 g/L) and monosodium glutamate (0, 5.0, 7.6, 11.4 or 15.2 g/L). Medium containing 10 g/L glucose, 5 g/L corn steep liquor and 7.6 g/L monosodium glutamate resulted the highest values of extracellula

14. Produção e caracterização parcial de poligalacturonases produzidas pelo fungo termofílico Monascus sp N8 e pelo termotolerante Aspergillus sp N12 em fermentação em estado sólido
A produção de poligalacturonases pelas linhagens fúngicas recentemente isoladas, Monascus sp N8 e Aspergillus sp N12, foi estudada através de fermentação em estado sólido usando como substratos misturas de farelo de trigo, bagaço da cana-de-açúcar e bagaço de laranja. A atividade máxima de exo-Pg produzida por Monascus sp (6,6 U/mL) foi obtida qu

15. Biopigments from Monascus: strains selection, citrinin production and color stability
Fungos do gênero Monascus são uma fonte promissora de corantes vermelhos naturais. No entanto, antes de se aplicar Monascus a alimentos, é importante selecionar linhagens capazes de produzir grandes quantidades de pigmentos, com o mínimo possível de citrinina. Além disso, a estabilidade de cor desses pigmentos deve ser adequadamente investigada. Com o

16. Concentration determination of extracellular and intracellular red pigments produced by Monascus sp
Monascus sp. é um fungo filamentoso cuja principal aplicação industrial está relacionada à sua capacidade de produzir pigmentos vermelhos, utilizados como corantes naturais em alimentos, em substituição aos sintéticos. Neste trabalho a produção de pigmentos vermelhos foi avaliada (por meio de espectrofotometria de varredura) em meio semi-sintético

17. Fungos filamentosos isolados de produtos derivados do milho comercializados em Recife, Pernambuco
A diversidade de fungos filamentosos foi analisada em três produtos derivados do milho: fubá, xerém e farinha de milho pré-cozida. Foi utilizado o método de plaqueamento em superfície e profundidade, utilizando meio de dicloran rosa de bengala cloranfenicol (DRBC). Foram isoladas 23 espécies de fungos filamentosos distribuídos em oito gêneros: Absid

18. Digenea (Trematoda) of Micropogonias furnieri (Desmarest) (Perciformes, Sciaenidae) from Rio Grande do Sul, Brazil
Micropogonias furnieri (Desmarest, 1823) from the coast of Rio Grande do Sul State were examined and six trematodes species were recovered: Aponurus laguncula Looss, 1907, A. pyriformis (Linton, 1910), Monascus filiformis (Rudolphi, 1819), Opecoeloides catarinensis Amato, 1983, O. stenosomae Amato, 1983, and Pachycreadium gastrocotylum (Manter, 1940). All sp

19. Pigment Production from Immobilized Monascus sp. Utilizing Polymeric Resin Adsorption
Pigment production by the fungus Monascus sp. was studied to determine why Monascus sp. provides more pigment in solid culture than in submerged culture. Adding a sterilized nonionic polymeric adsorbent resin directly to the growing submerged culture did not enhance the pigment production, thus indicating that pigment extraction is probably not a factor. Mon

20. Sexal reproductive cycle of Monascus in submerged shaken culture.
A strain of Monascus was grown in submerged, shaken culture using a glucose-salts mediumn. The formation of ascospores was studied by microscopic examination of samples taken at regular intervals for 6 days. All the stages of sexual reproduction previously described for Monascus were observed. The unusual feature of the strain studied was that it produced se

21. Production of Extracellular Pigment by a Mutant of Monascus kaoliang sp. nov
A hyperpigment-producing mutant, R-10847, was derived from Monascus kaoliang F-2 (ATCC 26264) through a series of mutagenesis steps. The mutant produced a large quantity of Monascus pigment when grown in mantou (steamed bread) by solid culture. The mutant produced pigments extracellularly by extruding the pigments outside the cell in a lump together with som

22. Biosynthetic Pathway of Citrinin in the Filamentous Fungus Monascus ruber as Revealed by 13C Nuclear Magnetic Resonance
Carbon isotope distribution of [13C]citrinin from Monascus ruber incubated with [13C]acetate revealed that the biosynthesis of the toxin originated from a tetraketide, instead of a pentaketide as has been shown for Penicillium and Aspergillus species. The production of polyketide red pigments and citrinin by M. ruber may therefore be regulated at the level o

23. Pigmentation and Antibacterial Activity of Fast Neutron- and X-Ray-induced Strains of Monascus purpureus Went
Seven new strains of Monascus purpureus Went were induced by neutron and x-ray irradiation. The quantity and quality of pigments produced by these strains differed. Strains N4S and N11S produced twice as much pigment as normal, while another strain, N14S, was albino. An unknown orange pigment was found in young colonies of the N11S strain. This orange pigmen

24. Production, Purification, and Characterization of α-Galactosidase from Monascus pilosus
A Monascus pilosus strain was selected for production of intracellular α-galactosidase. Optimum conditions for mycelial growth and enzyme induction were determined. Galactose was one of the best enzyme inducers. The enzyme was purified by ammonium sulfate precipitation, gel filtration, and ion exchange chromatography and was demonstrated to be homogeneous b
