Fructan from Erwinia herbicola.
Levan production by strains of Erwinia herbicola is common, and this property has some taxonomic significance for species differentiation within the "herbicola" group. The extracellular polysaccharide elaborated by strain 403 was characterized by nuclear magnetic resonance spectroscopy and methylation analysis. Results showed it to be a typical bacterial levan.
متن کاملErwinia tasmaniensis sp. nov., a non-phytopathogenic bacterium from apple and pear trees.
Bacteria were isolated from flowers and bark of apple and pear trees at three places in Australia. In Victoria, Tasmania and Queensland, strains with white colonies on nutrient agar were screened for dome-shaped colony morphology on agar with sucrose and were found to be closely related by several criteria. The isolates were not pathogenic on apples or pears. They were characterized by a polyph...
متن کاملErwinia gerundensis sp. nov., a cosmopolitan epiphyte originally isolated from pome fruit trees.
A survey to obtain potential antagonists of pome fruit tree diseases yielded two yellow epiphytic bacterial isolates morphologically similar to Pantoea agglomerans, but showing no biocontrol activity. Whole-cell MALDI-TOF mass spectrometry and analysis of 16S rRNA gene and gyrB sequences suggested the possibility of a novel species with a phylogenetic position in either the genus Pantoea or the...
متن کاملProduction of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola
To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...
متن کاملErwinia papayae sp. nov., a pathogen of papaya (Carica papaya).
Bacterial canker of papaya (Carica papaya) emerged during the 1980s in different islands of the Caribbean. Nineteen strains of Gram-negative, rod-shaped, non-spore-forming bacteria isolated from papaya were compared to 38 reference and type strains of phytopathogenic Enterobacteriaceae and related bacteria. Phylogenetic analysis of 16S rRNA gene sequences showed that the papaya strains belonged...
