identification and characterization of endophytic bacteria isolated from in vitro cultures of peach and pear rootstocks.endophytes are microorganisms which live symbiotically with almost all varieties of plant and in turn helping the plant in a number of ways. instead of satisfactory surface sterilization approaches, repeatedly occurring bacterial growth on in vitro rootstock cultures of peach and pear was identified and isolated as endophytic bacteria in our present study. five different isolates from peach rootstocks were molecularly identified by 16s rrna gene sequencing as brevundimonas diminuta, leifsonia sh ...201628330195
proposals of sphingomonas paucimobilis gen. nov. and comb. nov., sphingomonas parapaucimobilis sp. nov., sphingomonas yanoikuyae sp. nov., sphingomonas adhaesiva sp. nov., sphingomonas capsulata comb. nov., and two genospecies of the genus sphingomonas.based on the partial nucleotide sequence analysis of 16s ribosomal ribonucleic acid (rrna), presence of unique sphingoglycolipids in cellular lipid, and the major type of ubiquinone (q10), we propose sphingomonas gen. nov. with the type species sphingomonas paucimobilis (holmes et al, 1977) comb. nov. from the homology values of deoxyribonucleic acid-deoxyribonucleic acid hybridization and the phenotypic characteristics, three new species, sphingomonas parapaucimobilis, sphingomonas yanoikuyae, ...19902111872
predictive modeling for hot water inactivation of planktonic and biofilm-associated sphingomonas parapaucimobilis to support hot water sanitization programs.hot water sanitization is a common means to maintain microbial control in process equipment for industries where microorganisms can degrade product or cause safety issues. this study compared the hot water inactivation kinetics of planktonic and biofilm-associated sphingomonas parapaucimobilis at temperatures relevant to sanitization processes used in the pharmaceutical industry, viz. 65, 70, 75, and 80°c. biofilms exhibited greater resistance to hot water than the planktonic cells. both linear ...201627319816
isolation and characterization of indigenous endophytic bacteria associated with leaves of switchgrass (panicum virgatum l.) cultivars.to isolate and characterize indigenous bacterial endophytes from cultivars of switchgrass and study their antimicrobial and growth promoting potential.201323190162
sphingomonas yabuuchiae sp. nov. and brevundimonas nasdae sp. nov., isolated from the russian space laboratory mir.on the basis of phenotypic and genotypic characteristics and 16s rrna gene sequence analysis, novel species belonging to the genera sphingomonas and brevundimonas were identified from samples taken from the russian space laboratory mir. strain a1-18(t) was isolated from the air. 16s rdna sequence analysis showed that strain a1-18(t) formed a coherent cluster with sphingomonas sanguinis, sphingomonas parapaucimobilis, sphingomonas paucimobilis and sphingomonas roseiflava with sequence similarity ...200415143030
distribution of nevskia ramosa and other rosette-forming neustonic bacteria.samples from 27 natural and artificial aquatic environments were analyzed for the presence of rosette-forming bacteria by a combined cultivation and molecular biological approach. rosette-forming bacteria developed in 20 enrichment cultures with ammonia-free medium under air. three morphotypes could be distinguished. the most abundant type i resembled nevskia ramosa and formed hydrophobic, flat, and dichotomously branching rosettes. type ii rosettes were three-dimensional and were observed in 10 ...200415054677
