Abstract
Brown discoloration was observed in the crust of commercial frozen steamed stuffed buns (FSSBs) during resteaming. Culture-dependent and culture-independent analyses demonstrated that Serratia marcescens, a prodigiosin-producing species, was more abundant in spoiled samples than in unspoiled samples. Inoculation of experimental FSSBs with S. marcescens isolated from spoiled FSSBs confirmed that this species causes brown discoloration of FSSBs during resteaming. S. marcescens formed prodigiosin only between 15 and 28 °C but brown discoloration appeared only upon resteaming after storage at 4 °C. High-performance liquid chromatography analyses revealed that prodigiosin was absent from yellow-brown FSSBs. The pigmentation observed during resteaming is thus likely attributable to the intermediate 2-methyl-3-amylpyrrole. These findings provide valuable insights into the microbial contamination of FSSBs and will facilitate the prevention of spoilage of FSSBs.

Abstract
Prodigiosin is a red pigment commonly produced as a secondary metabolite by Serratia marcescens. It exhibits inherent bioactivities, including antimicrobial and anticancer, with low to no toxic effects on normal cells. The present study investigates a bioactive prodigiosin production from an atypical, red-pigmented, potentially novel Janthinobacterium sp. ERMR3:09 isolated from a glacial moraine. Statistically optimized culture parameters, i.e., w/v 1.0% glucose and 0.08% peptone as carbon and nitrogen sources, temperature 20 °C, and media pH 7, resulted in a four-fold increase in the pigment yield. The upscaled production in an 8 L volume resulted in higher pigment production within a shorter period of 48 h. The ultra-performance liquid chromatography (UPLC) analysis validated the identity of the purified pigment as prodigiosin that showed thermostability at 75 °C for 3 h. Evaluation of antimicrobial activity showed potent inhibitory effects (> 50%) against the opportunistic pathogenic fungal and Gram-positive bacterial strains. The pigment showed significant cytotoxicity (p < 0.05) towards A549 and HeLa cell lines with IC50 values of 42.2 μM and 36.11 μM, respectively. The study demonstrated that microbial communities from extreme niches can be ideal sources of bioactive pigments with immense pharmaceutical potential vital for the development of non-synthetic therapeutic agents.

Abstract
Microbial life present in the marine environment has to be able to adapt to rapidly changing and often extreme conditions. This makes these organisms a putative source of commercially interesting compounds since adaptation provides different biochemical routes from those found in their terrestrial counterparts. In this work, the goal was the identification of a marine bacterium isolated from a sample taken at a shallow water hydrothermal vent and of its red product. Genomic, lipidomic, and biochemical approaches were used simultaneously, and the bacterium was identified as Serratia rubidaea. A high-throughput screening strategy was used to assess the best physico-chemical conditions permitting both cell growth and production of the red product. The fatty acid composition of the microbial cells was studied to assess adaptation at the lipid level under stressful conditions, whilst several state-of-the-art techniques, such as DSC, FTIR, NMR, and Ultra-High Resolution Qq-Time-of-Flight mass spectrometry, were used to characterize the structure of the pigment. We hypothesize that the pigment, which could be produced by the cells up to 62 °C, is prodigiosin linked to an aliphatic compound that acts as an anchor to keep it close to the cells in the marine environment.

Abstract
Regulation of prodigiosin biosynthesis is received wide attention due to the antimicrobial, immunosuppressive and anticancer activities of prodigiosin. Here, we constructed a transposon mutant library in S. marcescens FS14 to identify genes involved in the regulation of prodigiosin biosynthesis. 62 strains with apparently different colors were obtained. Identification of the transposon insertion sites revealed that they are classified into three groups: the coding region of cyaA and two component system eepS/R and the promoter region of rpoH. Since the effect of cyaA and eepS/R genes on prodigiosin was extensively investigated in Serratia marcescens, we chose the mutant of rpoH for further investigation. Further deletion mutation of rpoH gene showed no effect on prodigiosin production suggesting that the effect on prodigiosin production caused by transposon insertion is not due to the deletion of RpoH. We further demonstrated that multicopy expression of RpoH reduced prodigiosin biosynthesis indicating that transposon insertion caused RpoH enhanced expression. Previous results indicate that RpoS is the sigma factor for transcription of pig gene cluster in FS14, to test whether the enhanced expression of RpoH prevents prodigiosin by competing with RpoS, we found that multicopy expression of RpoS could alleviate the prodigiosin production inhibition by enhanced RpoH. We proposed that multicopy expressed RpoH competes with RpoS for core RNA polymerase (RNAP) resulting in decreased transcription of pig gene cluster and prodigiosin production reduction. We also demonstrated that RpoH is not directly involved in prodigiosin biosynthesis. Our results suggest that manipulating the transcription level of sigma factors may be applied to regulate the production of secondary metabolites.

Abstract
Prodigiosin is a promising food color due to its antibacterial, antimalarial, antimycotic characteristics, immunomodulating, and antitumor activities. Novel prodigiosin producing strain isolated from sugarcane field soil of Banaras Hindu University, India, characterized as Serratia marcescens bhu prodig by 16 sRNA. The effect of carbon, nitrogen source, and physical parameters (pH and temperature) on pigment yield was studied. The highest amount of pigment produced, which was 800.95 ± 0.05 mg/L, was detected when sorbitol and peptone were used as nitrogen and carbon source with pH 7 at 30 °C. The optimized condition scale-up in a bioreactor with a working capacity of 3.0 L, gave maximum pigment yield of 825 ± 0.05 mg/L with µ (Maximum specific growth rate), Yp/x, which represents the product yield coefficient, and Yp/s, which signifies the specific product yield coefficient and productivity of 0.3/h, 0.62, 0.80, and 0.02 g/L/h, respectively, after 72 h of cultivation in submerged fermentation (SMF). The isolated pigment was characterized as prodigiosin by the analysis of spectral data and GC-MS. The mass spectrophotometry investigation characterized pigment as 4-methoxy-5(5 methyl-4-pentyl-2H-pyrrol-2-ylidene)- 2,2-bipyrrole ring structure. The GC-MS chromatogram showed m/z of 323, representing prodigiosin. The prodigiosin yield and productivity obtained in the current finding were higher than in previous reports.

Abstract
The antibacterial activities of prodigiosin are well-established but, as a hydrophobic molecule, the mechanisms used to introduce it to susceptible microbes has never been studied. We found here, in contrast to violacein, another hydrophobic antibiotic that can be transferred using membrane vesicles (MVs), prodigiosin is also carried from
Serratia marcescens
in MVs released but its resulting activities were severely mitigated compared to the freely added compound, suggesting it is more tightly bound to the MVs than violacein.

Abstract
The Rcs phosphorelay is a bacterial stress response system that responds to envelope stresses and in turn controls several virulence-associated pathways, including capsule, flagella, and toxin biosynthesis, of numerous bacterial species. The Rcs system also affects antibiotic tolerance, biofilm formation, and horizontal gene transfer. The Rcs system of the ocular bacterial pathogen Serratia marcescens was recently demonstrated to influence ocular pathogenesis in a rabbit model of keratitis, with Rcs-defective mutants causing greater pathology and Rcs-activated strains demonstrating reduced inflammation. The Rcs system is activated by a variety of insults, including β-lactam antibiotics and polymyxin B. In this study, we developed three luminescence-based transcriptional reporters for Rcs system activity and used them to test whether antibiotics used for empiric treatment of ocular infections influence Rcs system activity in a keratitis isolate of S. marcescens. These included antibiotics to which the bacteria were susceptible and resistant. Results indicate that cefazolin, ceftazidime, polymyxin B, and vancomycin activate the Rcs system to varying degrees in an RcsB-dependent manner, whereas ciprofloxacin and tobramycin activated the promoter fusions, but in an Rcs-independent manner. Although minimum inhibitory concentration (MIC) analysis demonstrated resistance of the test bacteria to polymyxin B and vancomycin, the Rcs system was activated by sub-inhibitory concentrations of these antibiotics. Together, these data indicate that a bacterial stress system that influences numerous pathogenic phenotypes and drug-tolerance is influenced by different classes of antibiotics despite the susceptibility status of the bacterium.

Abstract
Serratia marcescens is a bacterial species that produces an antibacterial pigment (Prodigiosin) showing a wide adaptive response to environmental stresses. The study aimed to investigate Prodigiosin production in S. marcescens wild-type strains, as well as its relation to photoprotection and antigenotoxicity against UVB. Prodigiosin yield was spectrophotometrically assayed in extracts of bacterial strains grown in different culture media. In vitro photoprotection efficacy was evaluated using the in vitro indices sun protection factor (SPFin vitro ) and critical wavelength (λc). The percentage of UVB antigenotoxicity estimates (%GI) in the SOS Chromotest was also evaluated. Correlation analysis was used to examine the relationship between Prodigiosin yield, SPFin vitro , %GI estimates and environmental traits (altitude, temperature, rainfall and solar irradiance). Prodigiosin yield in S. marcescens strains varied depending on culture media used for its growth, and it was correlated with environmental variables such as temperature and solar irradiance. SPFin vitro estimates were well correlated with Prodigiosin concentration and %GI values in the bacterial strains being studied. UVB photoprotective efficacy of the extracts obtained from S. marcescens strains depends on the strain's Prodigiosin yield and its antigenotoxic potential. The extracts with Prodigiosin yield higher than ˜17 μg mL-1 could be used as sources of sunscreen ingredients.

Abstract
Despite the great potential of Serratia marcescens in industrial applications, lack of powerful genetic modification tools limits understanding of the regulatory networks of the useful metabolites and therefore restricts their mass production. To meet the urgent demand, we established a genome-editing strategy for S. marcescens based on Red recombineering in this study. Without host modification in advance, nucA and pigA were substituted by PCR-amplified resistance genes. No long homologous arms were required at the two sides of resistance genes. Using this procedure, the fragment at the S. marcescens as large as 20 kb was easily deleted. Then we constructed a counter-selection gene kil constructed under the control of inducible PBAD operon, which demonstrates obvious lethality to S. marcescens. Subsequently, GmR-kil double selection cassette was inserted into the CDS of pigA gene. Using single-stranded DNA-mediated recombination, this insertion mutation was efficiently repaired through kil counter-selection. A powerful genetic modification platform based on Red recombineering system was successfully established for S. marcescens. Multiple types of modification and multiple recombination strategies can all be performed easily in this species. We hope this study will be useful for the theoretical research and the research of metabolic engineering in S. marcescens.

Abstract
Prodigiosin is a natural red pigment derived primarily from secondary metabolites of microorganisms, especially Serratia marcescens. It can also be chemically synthesized. Prodigiosin has been proven to have antitumor, antibacterial, antimalaria, anti-insect, antialgae, and immunosuppressive activities, and is gaining increasing important in the global market because of its great potential application value in clinical medicine development, environmental treatment, preparation of food additives, and so on. Due to the low efficiency of prodigiosin chemical synthesis, high-level prodigiosin of production by microorganisms are necessary for prodigiosin applications. In this paper, the production of prodigiosin by microorganism in recent decades is reviewed. The methods and strategies for increasing the yield of prodigiosin are discussed from the aspects of medium composition, additives, factors affecting production conditions, strain modification, and fermentation methods.

Abstract
Serratia marcescens is a prolific producer of the red, membrane-associated pigment prodigiosin. Earlier work has established both a positive role for prodigiosin in ATP production during the population lag phase and a negative role during high-rate, low cell density growth. This study uses the growth rate and growth phase modulation afforded by chemostat culture to extend prodigiosin functional analysis to the high-density and stationary phases. Cellular levels of prodigiosin were positively associated with cellular levels of ATP during high-density growth, and artificial pigment induction during this phase increased cellular ATP levels. Following peak high-density ATP per cell, the early stationary phase enabled significant population growth, while prodigiosin levels remained high and ATP declined. During the late stationary phase, ATP per cell was positively associated with prodigiosin per cell, while both declined during continued growth. These results provide correlational evidence for the multiple effects of prodigiosin pigment on ATP production throughout the growth cycle. Earlier work and the data presented here enable the formulation of a working model for the oscillating relationships between cellular levels of ATP and prodigiosin during batch culture.

Abstract
Rubber tree is an economically important tropical crop. Its endophytic bacterial strain Serratia marcescens ITBB B5-1 contains an intracellular macrovesicle and red pigment. In this research, the red pigment was identified as prodigiosin by quadrupole time-of-flight mass spectrometry. Prodigiosin has a wide range of potential medical values such as anticancer and antiorgan transplant rejection. The strain ITBB B5-1 accumulated prodigiosin up to 2000 mg/L, which is higher production compared to most known Serratia strains. The formation of the macrovesicle and prodigiosin biosynthesis were highly associated and were both temporal- and temperature-dependent. A mutant strain B5-1mu that failed to produce prodigiosin was obtained by ultraviolet mutagenesis. Whole genome sequencing of wild-type and mutant strains indicated that the PigC gene encoding the last-step enzyme in the prodigiosin biosynthesis pathway was mutated in B5-1mu by a 17-bp deletion. Transmission electron microscopy analysis showed that the macrovesicle was absent in the mutant strain, indicating that formation of the macrovesicle relied on prodigiosin biosynthesis. Immunoelectron microscopy using prodigiosin-specific antiserum showed the presence of prodigiosin in the macrovesicle, the cell wall, and the extracellular vesicles, while immuno-reaction was not observed in the mutant cell. These results indicate that the macrovesicle serves as a storage organelle of prodigiosin, and secretes prodigiosin into cell envelop and culture medium as extracellular vesicles.
