Associated research grant:14/01580-3 - Biotechnological process for the development of new natural colorants from microorganisms for industrial application, AP.JP


In last year's there is a trend to replace synthetic colorants by natural ones because they have lower adverse effects to human health, may possess biological activity, and are well accepted by consumers. These compounds can be produced by plants, insects and microorganisms; however, microorganisms have gained importance due to bioprocess that can generate high throughput. In this scenario, the filamentous fungi Penicillium purpurogenum, is not mycotoxigenic and is an alternative source of natural colorants with antioxidant and antimicrobial activity. Thereby, efficient techniques for the extraction and/or purification of these biocompounds from the fermented broth are of great interest aiming its industrial application. The objective of this project is to purify natural colorants from fermented broth of P. purpurogenum DPUA 1275 by liquid-liquid extraction with organic solvents, followed by determination of their chemical structure and evaluate aqueous two-phase systems based on Ionic Liquids (ABS-IL) as an alternative extraction technique. Initially the conventional technique liquid-liquid extraction using organic solvents of different polarities will be used to purify the natural colorants and subsequently, determinate its chemical structure by spectroscopic methods. In the second stage of this work, ABS-IL formed by different families of ionic liquids will be studied, followed by countercurrent chromatography to increase the purity of the extracted colorant. These techniques will be compared in order to show the effectiveness of the proposed alternative system. Thus, this project will address the extraction and/or purification of natural colorants by conventional and alternative techniques, which will be the basis for the extraction and/or purification of other compounds from microrganism.
