Question

5 multiple choice 0.8 points which organism produces a pigment only at room temperature, but not at 37c? escherichia coli staphylococcus epidermidis serratia marcescens micrococcus luteus previous

Explanation:

Serratia marcescens is known to produce a red pigment (prodigiosin) at room temperature (around 25°C). However, at 37°C (body temperature), the production of this pigment is inhibited. Escherichia coli does not produce such a temperature - dependent pigment. Staphylococcus epidermidis is usually white or light - colored and does not have this temperature - specific pigment production. Micrococcus luteus is typically yellow - pigmented and its pigment production is not temperature - regulated in this way.

Answer:

Serratia marcescens
