Biocolour Formation From Pigment Producing Bacteria And Its Application In Textile Industry.

Shweta Nakul, Poonam Gupta

Abstract :

In present study, two bacterial strains PG 1 and PG 2 isolated from fruit and vegetable waste soil sample are potential source for pigment production. On the basis of biochemical characterization,strains were belonged to Micrococcus species. The orange pigment produced by PG1 showed Rf value 0.76 and λmax was 350nm which was similar to torulene compound and yellow pigment produced by PG2 showedRf value 0.69 and λmax was 400nm which was similarto β–carotene compound. Germination assay showed that these pigments are nontoxicto plant. PG 2 species allowed the maximum seed germination percentage of 90% and PG 1 showed 85%. The two colours were used for dyeing of fies with lime as mordant and their wash performance showed that colours are stable. In future,present study can be implemented to replace synthetic colorants used in textile and dying industries.
