Abstract
Most dyes used in everyday life (e.g., for dyeing fabrics) are obtained by chemical synthesis which generate a vast amounts of environment pollution. In addition, the substrates for chemically obtained dyes are based on fossil fuels, which is also undesirable. Finding new, more environmentally friendly methods of obtaining pigments are the aim of many scientific research all over the world. In general, green synthetic pathways are preferred over common chemical reaction protocols in order to reduce the carbon footprint of the whole process. Therefore, in recent years, biosynthesis of synthetic dyes substituents have become more important. One of the examples of above approach is the biotechnological synthesis of indigoidine-based dyes. The aim of this research was to development of biotechnological approach for obtaining the indigoidine from the bacterial strain of the Pseudarthrobacter polychromogenes and to elaborate of method for extracting this dye. In order to notice the dye color changes in different solvents absorption measurements the indigoidine solution were carried out in water, acetone, acetonitrile, dimethyl sulfoxide, ethyl acetate, methanol and isopropanol in two aqueous solutions (2% formic acid solution, 10 mM ammonium acetate solution) and in mixture water and acetone solutions (2% formic acid solution, 10 mM ammonium acetate solution). To compare the differences in the spectra of the obtained dye and from comercial indigoidine, absorption measurements of the commercial dye were also performed.
