Purification and characterization of prodigiosin produced by integrated bioreactor from Serratia sp. KH-95

Antibacterial Colorants: Characterization of Prodiginines and Their Applications on Textile Materials

“…To confirm the pattern of all the carbon atoms, 13 C NMR, DEPT90, and DEPT135 spectra were generated (Table 2). On the basis of these spectra all the quaternary carbon, CH, CH 2 and CH 3 carbons were identified, and the 13 C NMR data were found to be identical to literature values (14,15), which supported the chemical structure of the compound (C2).…”

Production, Extraction and Characterization of Red Pigment Produced by Serratia rubidaea JCM 1240T isolated from Soil

“…Absorption spectrum of the pigment produced by Serratia rubidaea JCM was dependent on pH value similar to that reported earlier (Song et al, 2006). Thus at pH 2.0, the pigment was red and showed a maximum absorption at 535 nm, which is identical to that of prodigiosin hydrochloride.…”

“…Prodigiosin was reported to display a characteristic absorption spectrum in ethanol, with a maximum at 534 nm (Slater et al, 2003) and single peak absorbance at 535 Nm (Giri et al, 2004;Song et al, 2006;Montaner et al, 2000) extracted prodigiosin by shaking the S. marcescens 2170 cells with a mixture of methanol/lN HCl in the ratio 24:l.…”

Prodigiosin biosynthesis gene cluster in the roseophilin producer Streptomyces griseoviridis

“…[1][2][3][4] S. griseoviridis 2464-S5 produces prodigiosin R1 5 and roseophilin, 6 a structurally related compound containing two pyrrole and one furan rings, as shown in Figure 1. Roseophilin is considered to be biosynthesized partially with the same pathway as prodigiosin R1.…”
