Fungal pigments are extremely important for biotechnological exploitation. The present study was conducted to detect and analyze the pigments produced by selected Aspergillus and Penicillium isolates. The pigment producing fungi were isolated from soil and air. Fungi producing yellow and orange-red pigments were cultured on Potato dextrose broth and Czapek-Dox broth separately. Cellular pigments were extracted from mycelial mass and secretory pigments were extracted from culture filtrates using chloroform and ethyl acetate separately. Visible pigments were observed mostly in mycelial mass extracted in ethyl acetate. UV-Visible spectroscopic analysis provided detection of yellow pigment (380 nm) in Aspergillus isolate and orange-red pigment (463 nm) in Penicillium sp. The results also indicated that, the production of pigments in these fungi is dependent on the availability of nutrients in the medium. Extractability of the pigments was dependent on the solvent. These fungi may be exploited biotechnologically by maintaining suitable culture conditions for industrial production of pigments.

“…Estes são obtidos de plantas, insetos (Boo et al, 2012;Deveoglu et al, 2012;Unagul et al, 2005) e microrganismos (Cho et al, 2002;Jiang et al, 2005;Méndez et al, 2011;Yang et al, 2009), sendo que os últimos são os principais utilizados para a sua produção. Dentro deles, os fungos filamentosos possuem vasta versatilidade metabólica, o que possibilita o emprego dos mesmos em diversos processos industriais, como a produção de ácidos orgânicos, polissacarídeos, enzimas, alcaloides, antibióticos e colorantes (Babitha et al, 2007;ElEnshasy, 2007;Velmurugan et al, 2010).…”

RESUMO -Os líquidos iônicos (LIs) têm ganhado grande importância nas áreas da biotecnologia como solventes alternativos aos orgânicos, uma vez que a demanda por tecnologias mais limpas tem aumentado. Dentro deste tema, LIs podem ser adicionados a sistemas micelares de duas fases aquosas (SMDFA) para melhorar a extração de biomoléculas por esta técnica. SMDFA apresentam habilidade de manter as conformações e atividades das biomoléculas de interesse enquanto migram de fase sendo de grande interesse para extrair biomoléculas do meio fermentado. Assim, o objetivo deste trabalho foi avaliar e comparar a extração de colorantes naturais vermelhos produzidos por cultivo submerso de T. amestolkiae utilizando SMDFA composto pelo surfactante não-iônico TX-114 com cloreto de colina([Ch]Cl) e butanoato de colina ([Ch]But) como adjuvantes. Foram realizados experimentos para determinação das curvas binodais dos LIs e, posteriormente, experimentos de partição com os sistemas já caracterizados. O melhor sistema foi aquele que continha butanoato de colina em sua composição.

“…Li et al reported that the yield of hypocrellin under the solid-state fermentation (SSF) was about 0.2 mg/g [12]. Yang et al found that the strain S. bambusicola UV-62 produced hypocrellin by submerged fermentation, and the production could reach 0.0196% [13]. In our previous works, we had isolated and identified a new HA producing strain, Shiraia sp.…”

Hypocrellin A production by Shiraia sp. SUPER-H168 was studied under solid-state fermentation. Corn was found to be the best substrate after evaluating eight kinds of agro-industrial crops and residues. The optimized solid-state fermentation conditions were as follows: inoculum size 3 x 10(6) spores, substrate particle size 0.8-1 mm, initial moisture content 50%, and temperature 30 degrees C. Six kinds of external carbon source and seven kinds of external nitrogen source were evaluated, respectively, for HA production. Glucose and NaNO(3) were the best. The combination of them was optimized by the response surface method. The optimum compositions of the supplementary glucose and NaNO(3) were 1.65 g/100 g and 0.43 g/L, respectively. Hypocrellin A production reached 4.7 mg/g.
