Growth at 42°C Test- Principle, Procedure and Result Interpretation

What is Growth at 42°C Test? The growth at 42°C test is a presumptive identification test used to differentiate between the species of the fluorescent pseudomonas group as well as other non-fermentative bacteria. The test is based on the ability of an organism to grow at 42°C, which allows the differentiation of Pseudomonas aeruginosa from the other fluorescent pseudomonads. Temperature …
