Cov kab mob daj-pigmented, raug xaiv hom GZGR-4(T), raug cais tawm ntawm lub hauv paus ntawm Hylomecon japonica (Thunb.) Prantl thiab Kündig sau los ntawm Taibai Roob hauv Shaanxi Province, sab qaum teb-sab hnub poob Tuam Tshoj.Cells ntawm hom GZGR-4(T) yog Gram-negative, qws-zoo li tus, nruj me ntsis aerobic, non-endospore-forming thiab tsis-motile.Phylogenetic tsom xam raws li 16S rRNA gene sequences qhia tias hom GZGR-4(T) yog ib tug tswv cuab ntawm cov genus Sphingobium, nthuav tawm qhov zoo sib xws ntawm Sphingobium aromaticonvertens DSM 12677(T) (97.3%).16S rRNA cov noob caj noob ces zoo sib xws ntawm hom GZGR-4(T) thiab hom hom kab mob ntawm lwm hom Sphingobium nrog cov npe luam tawm siv tau los ntawm 93.4-96.5%.Qhov tseem ceeb ua pa quinone ntawm hom GZGR-4 (T) yog ubiquinone-10 (Q-10) thiab cov cellular fatty acids loj tau suav nrog feature 8 (suav nrog C18: 1 ω7c thiab / lossis C18: 1 ω6c), summed feature 3 ( suav nrog C16:1 ω7c thiab/los yog C16:1 ω6c), C16:0 thiab C14:0 2-OH.Spermidine yog polyamine loj.Polar lipid profile muaj phosphatidylglycerol, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, sphingoglycolipid, ib qho tsis paub phosphoglycolipid, ib qho tsis paub phospholipid, ib qho lipid unidentified aminolipid.DNA G + C cov ntsiab lus yog 63.6 mol%.DNA-DNA muaj feem xyuam rau hom GZGR-4(T) nrog rau kev hwm rau nws qhov ze tshaj plaws phylogenetic txheeb ze S. aromaticonvertens DSM 12677(T) yog 22.6 ± 5.3%.Raws li cov ntaub ntawv polyphasic taxonomic nthuav tawm, hom GZGR-4 (T) raug suav hais tias yog sawv cev ib hom tshiab ntawm genus Sphingobium, uas lub npe Sphingobium endophyticus sp.nov.yog npaj.The type strain is GZGR-4(T) (=CCTCC AB 2013305(T) = KCTC 32447(T)).
