The genus derxia first described in 1960 by H. L. Jenson. Derxia Gummosa are gram-negative bacteria found in tropical soils. It was named in honor of Dutch microbiologist Henri George Derx born in 1894. He was an industrial chemist who researched microbiology and botany. He would during the Second World War be imprisoned in a concentration camp during part of 1943 and 1944. He would go on to contribute to a number of areas including the discovery of a new genus of sporobolomycetaceae which he named Itersonilia perplexans. He also contributed to the discovery diacetyl the flavoring agent of butter.
