“…Aunque, no se ha definido su papel en la fisiología de la bacteria, se ha reportado su actividad antifúngica, bactericida, antitumoral y antiprotozoaria [21,22]. la cepa CCEI-1 de S. marcescens presentó un óptimo crecimiento con una pigmentación roja en agar BUG suplementado al 5% v/v con sangre (BIOlOG), agar Tributirina, agar Rhodamina B y agar MacConkey (Figura 5B), mientras que, en agar GEN, a pesar de tener un crecimiento óptimo, la pigmentación disminuyó por la presencia de la glucosa en el medio de cultivo que inhibió la síntesis de la prodigiosina (Figura 5A), posiblemente, debido a una represión catabólica [22,23].…”

“…marcescens es una bacteria mesófila pero hay reportes que indican que a 37°C disminuye su pigmentación [21]. En este estudio S. Marcescens CCEI-1a un pH de 8,0 tuvo la capacidad de sintetizar lipasas y el pigmento, (aunque con menor intensidad) a 50°C en el medio de cultivo mínimo FAM + aceite de oliva.…”

“…We have isolated a pink-red pigment prodigiosin, which has been reported to show several bioactive properties including antibacterial [45], anticancer [46], immunosuppressive [47], insecticidal [48] and larvicidal [49] activities. In this study, we have studied the antagonistic potential of prodigiosin against zygomycete and ascomycete fungi.…”

AbstractAssociation of bacteria with fungi is a major area of research in infection biology, however, very few strains of bacteria have been reported that can invade and reside within fungal hyphae. Here, we report the characterization of an endofungal bacterium Serratia marcescens D1 from Mucor irregularis SS7 hyphae. Upon re-inoculation, colonization of the endobacterium S. marcescens D1 in the hyphae of Mucor irregularis SS7 was demonstrated using stereo microscopy. However, S. marcescens D1 failed to invade into the hyphae of the tested Ascomycetes (except Fusarium oxysporum) and Basidiomycetes. Remarkably, Serratia marcescens D1 could invade and spread over the culture of F. oxysporum that resulted in mycelial death. Prodigiosin, the red pigment produced by the Serratia marcescens D1, helps the bacterium to invade fungal hyphae as revealed by the increasing permeability in fungal cell membrane. On the other hand, genes encoding the type VI secretion system (T6SS) assembly protein TssJ and an outer membrane associated murein lipoprotein also showed significant up-regulation during the interaction process, suggesting the involvement of T6SS in the invasion process.

“…The rapid production of its red flashy pigment, chemical nature, and the properties of prodigiosin has made it the subject of many studies into its possible industrial applications, especially as a food additive [1][2][3][4][5] . However, the usage of prodigiosin pigment is limited because its color quickly fades or changes upon exposure to light and it is insoluble in water 6 .…”

Encapsulation technique via spray drying can be employed to enhance the natural pigment's properties. In this study, spray-dried microparticles containing red pigment (prodigiosin) extracted from Serratia marcescens was produced using κ κ κ κ κcarrageenan and maltodextrin as encapsulation agents. The effect of spray-drying parameters on the encapsulation yield (EY), particle size and color intensity of the prodigiosin microcapsules were studied. The most intense color was obtained at a 1:1 ratio (volume ratio of prodigiosin in ethyl acetate to κ κ κ κ κ-carrageenan solution) with a 200 o C inlet temperature, a feed flow rate of 60 m 3 /h, a pressure of 1.5 bars and a feed rate of 3 mL/min. The characterization of spray-dried prodigiosin using FTIR and FESEM confirmed that the particles were properly coated with encapsulating agents and pigment morphology showed that the particles were regular shaped spheres. The results suggest that the spray-dried prodigiosin can be useful as a colorant under the above optimum operating conditions.
