What is Citrate Utilization Test? By measuring an organism’s ability to use citrate as its sole form of energy, the IMViC test (Indole, Methyl Red, Vogues-Proskauer, and Citrate Test) can discriminate between different types of organisms. One part of this examination is the Citrate Utilization Test. Along with the other IMViC tests, the citrate test …

Hydrogen Sulfide Test Definition The capacity of some microbes to break down molecules containing Sulphur (Sulphur) into hydrogen sulphide (H2S) during metabolism is frequently used as a laboratory test for microbiological confirmation. Methods for detecting H2S generation by bacteria are affected by the supply of Sulphur and the metal salts employed to indicate H2S creation. …
