EFFECTS OFTEMPERATURE AND pH ON THE GROWTH RESULTS 17 Resistance to Heat Treatment E. coli NIH] ]C-2,K. The former is smaller in size when compared to the average coliform bacteria. we can claim that production and growth duration was 24 h shorter. Serratia grow in many complex growth media, these include LB, PDA and NA [5-8]. Extremely low or high temperature and even pH are lethal to S. marcescens. Therefore, B. cereus surviving in final products may show a greater tendency to form the biofilm at higher temperatures than their optimal temperature in comparison with low temperatures. All Gram staining is based on 24-hour cultures. The oxygen relation of the microorganism was determined to be facultative; it had optimal growth when in- Effect of various stress conditions viz. Serratia marcescens is production of the red pigment, prodigiosin, at roomtemperature. Seed culture and optimum growth condition. In laboratory settings, Serratia species can grow on solid media at temperatures ranging from 20 C to 37 C while, in liquid media from 5 C to 40 C with optimum pH values of 5-9. Listeria monocytogenes and Serratia marcescens had an optimum growth at a temperature of 35C, after which there was a steep decline in bacterial growth due to bacterial death.

S. marcescens is an opportunistic pathogen which can live in a variety of environments, including inside insect and mammalian hosts, 76 with an optimal growth temperature close to 31 C (Grimont and Grimont, 1978; Flyg et al., 1980; Ketola et al., 2013). with a growth optimum between 25C and 40C (Madigan, 2002). Serratia marcescens is best known for its red or pink pigment (Fig. Serratia marcescens]. Maximum enzyme activity was expected at 20C for Chrombacteriaceae . "Serratia has dark history in region".SFGate. This is owing to the fact that ribosome and enzyme deactivation may occur at temperatures below or above the optimal temperature (30 C). (A) S. marcescens incubated at room temperature for 16 hours. Envi-ronmental conditions such as temperature of in-cubation and type of growth medium influence pigment formation, although the effects of these conditions were not thoroughly examined in quantitative terms. G. stearothermophilus grow in temperatures ranging from 30-75 degrees C, with an optimal growth temperature at 55C. Figure 2: Counting cells by colony growth and optical density. Perhaps it is noteworthy that the optimal growth range for Serratia marcescens is 25-37C, and it is above this temperature range that pigment production ceases. A factorial design was applied to generate a set of 32 experimental combinations to study the optimal conditions for pigment production using crude glycerol obtained from local biodiesel facility as carbon source for the growth of Serratia marcescens.

In addition, it can survive in soapy chlorhexidine . Perhaps the most well-known and defining characteristic of certain Serratia spp., including S. marcescens, is the production of a reddish pigment known as prodigiosin (Figure 2a).2 Certain strains can also produce another pigment, known as pyrimine.2 Colony pigmentation The bacterial strain was found to grow between 4 to 45C (opt. Thermophiles Optimal growth between 50C and 80C. The best nitrogen and carbon source for production were found to be peptone and maltose with . S. marcescens, optimal growth temperature is 37C, but optimal temperature for enzymatic activity (not for all enzymes) is 25C, because only at this temperature the orange-red prodigiosin pigment is produced. Most strains produce abundant pigment from 25-30 C, although the bacteria grow from 4-42C; the pigment may form at 12 . Once the growth temperature of Serratia marcescens is raised to 37 degrees, the pigment stops being produced. S. marcescens IBB Po15 cells grown at 37C produced protease and the enzyme production decreased in cells exposed to aromatic compounds, as compared with the control cells.
