pseudomonas peli pseudomonas peli pseudomonas peli is a gram-negative, non-fluorescent, non-sporulating, motile, rod-shaped bacterium isolated from a commercially available nitrifying inoculum used in aquaculture. the type strain is lmg 23201. after approximately 24 hours of growth at 28 °c in tryptic soy agar medium, pseudomonas peli colonies are 1–2 mm in diameter, beige to yellow in color and have non-uniform edges while the cells themselves are rod shaped (width near 1μm and length between 2-3 μm) with rounded ends. cells are motile, do not form spores, are non-fluorescent and they have not been observed to grow anaerobically. pseudomonas peli scientific classification domain: bacteria phylum: pseudomonadota class: gammaproteobacteria order: pseudomonadales family: pseudomonadaceae genus: pseudomonas species: p. peli binomial name pseudomonas pelivanparys, et al., 2006
