Aspergillus Niger Gh1

This work was performed to study Castilla Rose (Purshia plicata) as a potential source of polyphenols obtained by solid-state fermentation (SSF)-assisted extraction using the microorganism Aspergillus niger GH1 and to evaluate the antioxidant activity of the extracted compounds. First, water absorption capacity (WAC) of the plant material, radial growth of the microorganism, determination of best fermentation conditions, and maximum accumulation time of polyphenols were tested. Then, a larger-scale fermentation, polyphenols isolation by column liquid chromatography (Amberlite XAD-16) and recovered compounds identification by HPLC-MS were made. Finally, the antioxidant activity of the recovered compounds was tested by ABTS, DPPH, and lipid oxidation inhibition assays. The best fermentation conditions were temperature 25 °C and inoculum 2 × 106 spores/g, while the maximum extraction time of polyphenols was 24 h (173.95 mg/g). The HPLC/MS analysis allowed the identification of 25 different polyphenolic compounds, and the antioxidant activity of the obtained polyphenols was demonstrated, showing ABTS assay the most effective with inhibition of 94.34%.

Curcuma longa L. es una especia aromática originaria del sudeste asiático, su rizoma tiene aplicaciones en las industrias de alimentos y farmacéutica debido a que su principal fitoquímico es la curcumina, la cual se ha extraído por diversos métodos (maceración, Soxhlet, ultrasonido, microondas etc.). El objetivo del presente trabajo fue explorar la extracción de pigmentos de la cúrcuma asistida por fermentación en estado sólido (FES) empleando cepas fúngicas. Se utilizaron 3 g de material seco con 70% de humedad del rizoma como soporte suplementado con el medio Czapek-Dox para el crecimiento de Aspergillus niger GH1 y PSH, Aspergillus oryzae DIA-FM, Aspergillus sp. ITV, y Aspergillus terreus ITV. Las condiciones de fermentación fueron 25 °C por 240 h, midiendo el crecimiento radial cada 24 h y cuantificando a tiempo final el contenido de curcumina. Los resultados obtenidos demostraron la capacidad de crecimiento de cada cepa sobre el material vegetal, siendo A. niger GH1 y PSH las que tuvieron mayor velocidad de crecimiento (0.039 h-1 y 0.036 h-1 , respectivamente) así como la mayor capacidad para liberar curcumina (58.42 y 58.21 mg/g). La FES es un método útil para la extracción de curcumina utilizando cepas del género Aspergillus.

Eleven fungal strains (4 Penicillium commune, 2 Aspergillus niger, 2 Aspergillus rugulosa, Aspergillus terricola, Aspergillus ornatus and Aspergillus fumigatus) were isolated, characterized morphologically and by their capacity to degrade tannins. Aspergillus niger Aa-20 was used as control strain. Several concentrations of hydrolysable tannin (tannic acid) were used as sole carbon source. All strains were able to degrade hydrolysable tannins. Aspergillus niger GH1 and PSH showed the highest tannin-degrading capacity (67 and 70%, respectively). Also, the fungal capacity to degrade condensed tannin (catechin) was tested. Aspergillus niger PSH and Penicillium commune EH2 degraded 79.33% and 76.35% of catechin. The results demonstrated the capacity of fungi to use hydrolysable and condensed tannins as carbon source.
