Indigo is one of the brilliant blue dyes, which was used to be extracted from plants, but now synthesized chemically. Indigo is also produced by bacteria. In recent years, Ensley, B. D. (1983) and Mermod, N. (1986) reported a pathway producing indigo of bacteria. We are currently studying indigo formation by bacteria. Using Pseudomonas sp. S13 harboring naphthalene degradation plasmid as donor and E. coli as recipient, conjugates and transformants with the plasmid were obtained. The conjugates and transformants were not only able to grow in medium with naphthalene as the sole carbon and energy source, but also to synthesize indigo in Lennox medium. The conjugates and transformants were grown in Lennox medium at 30 degrees C for 48 hr then resulted in synthesis of indigo. The production of indigo is increased in the presence of tryptophan or indole. Indigo formation was enhanced if the bacteria was grown in a medium supplemented with either 0.1% of naphthalene or 1% of salicylic acid. The present work opens a field for the synthesis of dyes by microbes and it might shed light on the potential use in controlling environmental pollution by engineering bacteria.
