Abstract
The biosynthesis of prodigiosin (PG) from Serratia marcescens involves the coupling of a bipyrrole, 4-methoxy-2,2'-bipyrrole-5-carboxaldehyde (MBC), with a monopyrrole, 2-methyl-3-n-amyl-pyrrole (MAP), and formation of a linear tripyrrole (PG). We constructed mutant strains in which either the MBC biosynthesis by S.marcescens BMJ816 or the MAP biosynthesis by S.marcescens AMJ817. S.marcescens BMJ816 and AMJ817 confirmed that they lose the ability to synthesize PG when they are cultivated alone. An experiment was also conducted in which cultures of the two mutant strains were grown to the early exponential phase in a semi-defined medium, and one suspension culture was inoculated with the other. This approach yielded 103mg/L PG. The findings suggest that the addition of precursors may enhance PG production by microorganisms.
