Answer:Serratia genes for pigment production are induced at certain temperatures
Explanation:
The red pigment production is dependents on temperature.
Some bacteria are thermophile doing very well in extreme temperature while some are very sensitive to temperature changes.
The red pigment production is regulated by certain gene in the bacteria but can only be activated at certain temperature. 25°C was suitable for the red pigmentation that is why the plate color changed this indicate the sensitivity of the pigment production to temperature changes.
Conclusion - To get the best of serratia it is best to keep them at a temperature lower than the normal room temperature for the gene to be activated and full express itself.
