Abstract

In this research work, a microorganism of the genus Streptomyces sp. was isolated and 3 ATCC bacteria of the genus Streptomyces (S. violaceoruber, S. puniceus, S. albidoflavus) were used, which were financed thanks to the Le Qara research center. Sampling was carried out in the city of Arequipa in the districts of Cayma and La Joya, and a strain of the genus Streptomyces with the ability to produce blue extracellular pigment was isolated and characterized macroscopically and microscopically. The production of the natural pigment produced by the native strain was evaluated, achieving favorable results, using the Gauses medium, as well as for the species S. albidoflavus, S. violaceoruber, while for S. puniceus the results were not satisfactory. After the production of pigments, alpaca fiber, cotton fiber and acrylic wool were dyed with alum and acetic acid as mordant using the pigments produced by the species of the genus Streptomyces and finally the color of each of them was identified using the reading in CMYK, RGB, HEX and Pantone coordinates.  It is concluded that using bacteria of the genus Streptomyces it is possible to produce natural pigments that can be used in the dyeing of textile fabrics.
