The conversion of ammonia nitrogen to nitrite and nitrate forms of nitrogen has aroused much attention in the past and continues to receive much of the energy of the present day researcher.
It has been known for many years that the phenomenon of nitrification is almost in its entirety a biological process. In 1862, Louis Pasteur demonstrated the microbiological nature of the oxidation of alcohol to acetic acid. He suggested that the oxidation of ammonia might be of similar nature. In 1877 this suggestion was verified by schloesing and Muntz, and for the next ten years the process received much attention, culminating in 1891 in the isolation of the responsible organisms by Winogradsky.
