| paracoccus contaminans sp. nov., isolated from a contaminated water microcosm. | a beige-pigmented, oxidase-positive bacterial strain (wpan02t), isolated as a presumably airborne contaminant of an axenic bacterial microcosm, was studied using a polyphasic taxonomic approach. cells of the isolate were coccoid and stained gram-negative. a comparison of the 16s rrna gene sequence of strain wpan02t with sequences of type strains of the most closely related species of the genus paracoccus showed highest sequence similarities to paracoccus chinensis (97.7 %), paracoccus marinus (9 ... | 2016 | 27599853 |
| paracoccus cavernae sp. nov., isolated from a show cave. | a gram-stain-negative, aerobic, non-motile, non-spore-forming bacterium, strain 0511ard5e5t, was isolated from an air sample collected in ardales cave (malaga, spain). strain 0511ard5e5t grew at 4-37 °c and in the presence of 0-4 % (w/v) nacl [optimally at 25 °c and with 1 % (w/v) nacl]. cells were catalase- and oxidase-positive. the major respiratory quinone was ubiquinone-10. the predominant fatty acids were c18:1ω7c and c16:0. the dna g+c content was 63.2 mol%. phylogenetic analysis based on ... | 2016 | 26971128 |
| paracoccus chinensis sp. nov., isolated from sediment of a reservoir. | a gram-negative, short ovoid- to coccus-shaped, aerobic, motile, non-spore-forming bacterium (designated strain ks-11(t)) was isolated from sediment of the eutrophic guanting reservoir in beijing, china. colonies grown on r2a agar plates were circular, convex and colourless to orange. the strain grew in the presence of up to 1 % nacl (optimum, 0 % nacl). growth occurred at 25-40 degrees c (optimum, 28-37 degrees c) and at ph 6.0-9.5 (optimum, ph 7.5-9.0). on the basis of 16s rrna gene sequence s ... | 2009 | 19625438 |
| paracoccus aestuarii sp. nov., isolated from tidal flat sediment. | a gram-negative micro-organism, designated strain b7(t), was isolated from tidal flat sediment and subjected to a polyphasic taxonomic study involving morphological, physiological, biochemical and 16s rrna gene sequence analyses. a phylogenetic analysis based on the 16s rrna gene sequence indicated that strain b7(t) belonged to the genus paracoccus and was closely related phylogenetically to paracoccus marcusii mh1(t) (97.5 % sequence similarity), paracoccus marinus kkl-a5(t) (97.5 %), paracoccu ... | 2009 | 19329608 |
| paracoccus marinus sp. nov., an adonixanthin diglucoside-producing bacterium isolated from coastal seawater in tokyo bay. | two novel marine, gram-negative, non-motile, catalase- and oxidase-positive, aerobic bacteria were isolated from coastal seawater in tokyo bay. analysis of almost-complete 16s rrna gene sequences showed that the two isolates are members of the genus paracoccus, sharing highest 16s rrna gene sequence similarity (96.5 %) with paracoccus aminophilus nbrc 16710(t). the dna-dna reassociation values between p. aminophilus nbrc 16710(t) and these isolates were only 10-20 %, in contrast to the high dna ... | 2008 | 18218935 |
| major carotenoid isolated from paracoccus schoinia nbrc 100637t is adonixanthin diglucoside. | the structure of a novel major carotenoid glycoside (nearly 80% of total carotenoids) from a newly isolated bacterium, paracoccus schoinia nbrc 100637t, was determined to be adonixanthin diglucoside using spectral data. by contrast, carotenoid diglycosides are rare and are usually minor carotenoids in nature. the minor carotenoids in this bacterium included astaxanthin diglucoside, zeaxanthin diglucoside, canthaxanthin, echinenone, zeaxanthin, beta-cryptoxanthin, and beta-carotene. | 2006 | 17190471 |
| paracoccus niistensis sp. nov., isolated from forest soil, india. | a gram-negative, non-motile, catalase-positive and oxidase-positive, aerobic bacterium designated as nii-0918(t) was isolated from soil sample in western ghat forest, india. 16s rrna gene sequence analysis showed that strain nii-0918(t) belongs to the subclass α-proteobacteria, being related to the genus paracoccus, and sharing highest sequence similarity with paracoccus chinensis nbrc 104937(t) (99.4%), paracoccus marinus nbrc 100640(t) (97.3%), paracoccus koreensis ch05(t) (97.1%) and paracocc ... | 2010 | 20936429 |
