What is Elicitation of Streptomyces coelicolor with dead cells of Bacillus subtilis and Staphylococcus aureus in a bioreactor increases production of undecylprodigiosin about?

Since microorganisms normally co-exist with other species in nature, they have developed complex metabolic and physiological responses as a result of such interspecies interactions. We utilized some of these interactions by introducing heat-killed cells of Bacillus subtilis and Staphylococcus aureus to Streptomyces coelicolor cultures and, as a result, stimulated undecylprodigiosin production. Undecylprodigiosin is not only an antibiotic; it has also been attributed with antitumor activities, but, in a defined medium, pure cultures of S. coelicolor produced only low concentrations. Elicitation with B. subtilis increased the maximum undecylprodigiosin concentration by threefold and S. aureus by fivefold compared with the pure culture of S. coelicolor. Growth and glucose consumption of elicited S. coelicolor, however, remained similar to those observed in the pure culture. Furthermore, another positive outcome of the elicitation with both B. subtilis and S. aureus was the earlier onset of undecylprodigiosin production by 24 h compared with the pure culture of S. coelicolor. This is the first time that such a phenomenon has been seen in 2L bioreactors. Our work supports the use of bio
