It was first isolated from sediment samples from hydrothermal systems collected in the Azores. The species is named in honor of German-American microbiologist Alfred M. Spormann, in recognition of his work on the field microbial electrosynthesis.
The optimum growth temperature for "K. spormannii" is 55 °C, and can grow in the 45-65 °C range. Its optimum pH is 5.5, and grows in pH range 4.5-7.0.
