Paraburkholderia elongata
Paraburkholderia elongata is a Gram-negative bacterium belonging to the genus "Paraburkholderia". The type strain is "P. elongata" 5N, which was isolated from the Arnot research forest, near Van Etten, New York, using agar medium supplemented with soil-extracted, solubilized organic matter. The same isolation effort and methodology led to the isolation of "P. solitsugae" 1N. "P. elongata" was named after its tendency to form elongated, filamentous cells when grown in concentrated growth media. Phosphate concentration was found to regulate the conditional filamentation of "P. elongata", resulting from the accumulation of intracellular polyphosphate.
