Background: Nowadays, the use of the organic pigments produced by the microorganisms according ‎to their nature and safety is increasing. These pigments are various in their nature and have different ‎properties. The aim of the recent research was to extract the new bacterial pigments that are produced ‎in the cold environments. ‎ Materials and methods: Ten soil samples from different areas of Torghabeh city were collected and ‎cultivated. Ten days after, 14 pigmented bacterial colonies were selected then the isolates were ‎identified using the biochemical tests and polymerase chain reaction (PCR). Using the methanol and ‎glass powder, bacterial pigments were extracted and in order to purification TLC was performed. ‎Pigments of two strains, A8 and A13, which had a suitable purity, were used for cell toxicity using ‎three cell lines HepG2, human embryonic fibroblasts, and gastric cancer. ‎ Results: Among 14 pigmented bacterial strains, the strain A8 that was Aeromonas hydrophyla, could ‎prevent the growth of the cells on different cancerous cell line. Also, the pigment that was named A13, ‎had no cytotoxic effects on all the used cell types and can be used as a natural coloring agent in the ‎food industry. ‎ Conclusion: As the results indicate based on the biological properties of the extracted bacterial ‎pigments, they can be used in different areas such as medicine and technology.‎ Keywords: Psychrotrophic bacteria, Pigments, Food industry, Anti cancer effect.‎
