Proskauer

Biochemical tests are usually performed after pure cultures have been obtained. The standard indole, methyl red, Voges-Proskauer, citrate, and litmus milk tests may be used to show important physiological characteristics. To study the functional diversity of bacteria, the utilization of carbohydrates, amines, amides, carboxylic acids, amino acids, polymers, and other carbon and nitrogen sources can be tested.28 Dilution-based most-probable number (MPN) techniques with phospholipid fatty acids as biomarkers have been employed for studying different bacterial species in lakes.40 The patterns of antibiotic resistance in bacteria isolated from natural waters have been useful for identifying sources of water pollution.34...

Along with the need to "spread the news" of polymer science was the increasing need to develop an adequate vehicle which would focus on the dissemination of generated experimental results in polymer chemistry. In 1940 Drs. Maurits Dekker and E.S. Proskauer of Interscience Publishers consented to begin the publication of a series of Monographs on polymer chemistry, "High Polymers", with H. Mark and G.S. Whitby as editors. The response was so positive...

According to Levine, the methyl red test checks with the Voges-Proskauer reaction. The test for B. coli of fecal origin is the development of a red coloration in the medium after twelve hours incubation. 

Methyl red medium is made by adding methyl red to a phosphate broth and Voges-Proskauer medium is made by adding 10% KOH solution to the phosphate broth.
