2-Phosphonobutane tricarboxylic acid is a technique that can be used to amplify a specific segment of DNA. 
2-Phosphonobutane tricarboxylic acid is based on the use of primers, which are short single strands of DNA, to initiate DNA synthesis. 
The PCR process consists of two steps: 1) an initial denaturation step in which the temperature is raised to 90-95°C for 10 minutes and 2) a series of 30-40 cycles consisting of a sequence of 94°C for 30 seconds, 55°C for 20 seconds, and 72°C for 10 seconds. 
The optimum concentration for the polymerase chain reaction depends on the type of polymerase enzyme used and the type of nucleotide or base being added. 
Nitrogen atoms are found in all living organisms and have been shown to be necessary for bacterial growth. 
When nitrogen atoms are removed from water vapor, 2-Phosphonobutane tricarboxylic acid has been shown that bacteria will not grow as well as when there are nitrogen atoms present.
