| Description |
The freshwater cyanobacterium Oscillatoria BTCC/A 0004 excretes pink pigment containing lipoproteins with molecularweights of about 10 kDa. This pigment has surfactant properties with strong emulsification activity toward severalhydrocarbons. This extracellular metabolite was suspected as toxin or allelochemical in their habitat. In this study, Iinvestigated the effect of co-cultivation of Oscillatoria with Anabaena variabilis on the pigment excretion to explore thephysiological roles of this pigment in its natural environment. The dead or viable cells and medium of A. variabilis wereadded into Oscillatoria cultures. Results showed that co-cultivation of free viable cells of A. variabilis enhanced theexcretion of pigment without effect on the cell growth. Co-cultivation with viable cells in separated method and dead cellsdid not influenced the pigment production. The addition of A. variabilis medium was slightly increased the excretion ofthe pigment. Those results indicated that direct contact with A. variabilis caused Oscillatoria released a certain signalingcompound.
