Originally designated in the genus Chryseomonas, the species has since been reassigned to the genus Pseudomonas. MorphologyPseudomonas luteola is a Gram-negative, motile aerobe. Its motility is created by multitrichous flagella. They grow as rods of 0.8 μm to 2.5 μm.[2] Colonies produce a yellow-orange pigment. Optimal temperature for growth is 30 °C. Importantly for classification, it grows best on heart infusion agar supplemented with 5% horse blood.[3] It is also able to grow on TSA, Nutrient Agar, Mac Conkey or CASA Agar.[2]BiosorptionPseudomonas luteola can absorb certain heavy metals such as Cr(VI) and Al(III).[4] Both ions are found in industrial wastewaters.[4] These metals are specifically targeted by P. luteola strain TEM05.[4] Under relatively acidic conditions (pH: 4 and 5 for each ion respectively).[4] Experiments indicated a maximum adsorption capacity of 55.2 mg g−1 for Al(III) and 3.0 mg g−1 for Cr(VI).[4]This same strain is also known to produce an exopolysaccharide (EPS) utilized in the adsorption of nickel and copper.[5] In order to adsorb Ni and Cu at significant levels, the strain must be immobilized in a calcium alginate beads. With this enhancement, maximum adsorption capacities range from 45.87–50.81 mg g−1 and 52.91–61.73 mg g−1, respectively.[5] PathenogenicityThe pathogenic form of Pseudomonas luteola is a saprophyte.[2] It is an opportunistic pathogen that can cause bacteremia, meningitis, prosthetic valve endocarditis, peritonitis in humans and animals.[2] P. luteola is registered by the CDC as group Ve-1.[3] Most strains are susceptible to broad-spectrum antibiotics, such as cephalosporins, aminosids, and ciprofloxacin.[3] However, infections associated with foreign material are highly resistant, and infected prostheses have to be removed if possible.[3] References1. ^{{cite journal |doi=10.1099/00207713-47-2-249 |title=The Phylogeny of the Genera Chryseomonas, Flavimonas, and Pseudomonas Supports Synonymy of These Three Genera |year=1997 |last1=Anzai |first1=Yojiro |last2=Kudo |first2=Yuko |last3=Oyaizu |first3=Hiroshi |journal=International Journal of Systematic Bacteriology |volume=47 |issue=2 |pages=249–51 |pmid=9103607}} 2. ^1 2 3 http://www.tgw1916.net/Pseudomonas/luteola.html{{full citation needed|date=January 2013}} 3. ^1 2 3 {{cite journal |doi=10.1128/JCM.42.4.1837-1839.2004 |title=Chryseomonas luteola Identified as the Source of Serious Infections in a Moroccan University Hospital |year=2004 |last1=Chihab |first1=Wafae |last2=Alaoui |first2=Ahmed S. |last3=Amar |first3=Mohamed |journal=Journal of Clinical Microbiology |volume=42 |issue=4 |pages=1837–9 |pmid=15071064 |pmc=387548}} 4. ^1 2 3 4 {{cite journal |doi=10.1007/s00253-003-1479-0 |title=Chromium and aluminum biosorption on Chryseomonas luteola TEM05 |year=2004 |last1=Ozdemir |first1=G. |last2=Baysal |first2=S.
