What is the function of prodigiosin?
Prodigiosin received renewed attention for its wide range of biological activities, including activities as antimalarial, antifungal, immunosuppressant, and antibiotic agents. It is perhaps best known for its capacity to trigger apoptosis of malignant cancer cells.
What is the function of prodigiosin in Serratia marcescens?
Prodigiosin is a red pigment produced as a secondary metabolite by Serratia marcescens, characterized with unique tripyrrole structure which is regarded as responsible for its reported pharmacological characteristics as anti-cancer, anti-microbial, anti-oxidant and immunosuppressant [4] and it s unique application as a …
Is prodigiosin sensitive to temperature?
The paper above does state that temperature does effect prodigiosin expression. Such that at higher temperatures a physiological response is invoked rather than a genetic change in prodigiosin expression. Besides temperature, pH and nutrients are important in prodigiosin expression (pigment expression).
What media does Serratia marcescens grow on?
Serratia, like other Enterobacteriaceae, grow well on ordinary media under anaerobic and aerobic conditions. They grow well on synthetic media using various compounds as a single carbon source. Optimum growth of all strains of Serratia has been observed at pH 9 and at temperatures from 20–37°C.
Where is prodigiosin found?
Prodigiosin, a red linear tripyrrole pigment, is normally secreted as a secondary metabolite of microbial origin. Its native producer is the opportunistically pathogenic bacterium Serratia marcescens.
How do you extract prodigiosin?
These colonies were inoculated into the LB broth and placed in CO2 incubator under room temperature for 48 hrs. After 48 hrs, the prodigiosin pigment was observed. Serratia strain was extracted from the soil and streaked on Luria Bertani agar plate. The plate was placed at room temperature for 48 hrs.
What is the optimal temperature for production of prodigiosin?
Williams et al. (1971) defined 27°C as the optimum temperature for prodigiosin production in S. marcescens, and that the pigment is synthesized during the stationary phase of growth.
Is prodigiosin production dependent on certain environmental conditions?
The production of prodigiosin has been observed to be effected by several environmental factors, inorganic phosphate availability, media composition, temperature and pH (Williamson et al.
Does Serratia marcescens grow on blood agar?
Serratia marcescens. Medium-sized colonies that appear buff in colour on Blood Agar. The bacteria produce a red pigment which is easily seen when grown on blood-free media such as nutrient agar or Kings agar B. This culture has been incubated at 30°C.
Is prodigiosin a protein?
A protein associated to prodigiosin formation was found in Serratia marcescens. The protein was not found in nonpigmented strains and was correlated with the pigment level.
What temperature does E coli grow?
E. coli is a mesophilic bacterium able to grow well in the temperature range from 21 °C to 49 °C, with an optimum at about 37 °C.
