Bacterium formosanum Okabe 1935: Chlorobacter cichorii Patel and Kulkarni 1951, probable synonym: Pseudomonas papaveris
Lelliott and Wallace 1955).
Gram negative rods, 0.7-0.8 x 0.2-3.6 μm, motile with polar multitrichous flagella.
Colony morphology: circular, convex, smooth, glossy, translucent.
Produce fluorescent diffusible pigment, particularly in iron-deficient media. No lipolytic.
No slime produced on sucrose media.Obligately aerobic, optimal growth temperature
30-35 ºC. No growth at 41 ºC.
Organic growth factors not required. Growth slow in mineral media with single carbon
sources and relatively slow in complex media.
Media: Trypticase Soy Agar, Nutrient agar, LB medium, King’s medium B.
Isolated from Cichorium intybus and Cichorium endivia.
Pathogen to plants – leaf spotting and blighting in Cichorium spp., Lactuca sativa, Chrysanthemum morifolium (also, few reports for  
Plecthrantus australis, Hedera helix, Curcuma longa, Ocimum basilicum L., Brassaia actinophylla, Dizygotheca elegantissima,
Gerbera jamesonii, Polyscias fruticosai
