Pseudomonas fildesensis sp. nov., a psychrotolerant bacterium isolated from Antarctic soil of King George Island, South Shetland Islands
The strain KG01(T) was isolated from a soil sample from King George Island, Antarctica. Cells of KG01(T) are rod-shaped and motile by means of multiple polar flagella. The absence of arginine dihydrolase activity could be a key feature to readily distinguish KG01(T) from its closest phylogenetic rel...
