Leuconostoc kimchii sp. nov., a new species from kimchi.
A Gram-positive, catalase-negative, facultatively anaerobic, coccus-shaped bacterium, designated IH25T, was isolated from kimchi, a traditional Korean vegetable product. Phylogenetic analysis based on almost complete 16S rDNA sequences placed the isolate in a monophyletic clade corresponding to the genus Leuconostoc. All validly described species in the genus Leuconostoc, with the exception of ...
متن کاملIdentification and characterization of Leuconostoc fallax strains isolated from an industrial sauerkraut fermentation.
Lactic acid bacterial strains were isolated from brines sampled after 7 days of an industrial sauerkraut fermentation, and six strains were selected on the basis of susceptibility to bacteriophages. Bacterial growth in cabbage juice was monitored, and the fermentation end products were identified, quantified, and compared to those of Leuconostoc mesenteroides. Identification by biochemical fing...
متن کاملVancomycin-resistant streptococci or Leuconostoc sp.
Two strains of gram-positive cocci highly resistant to vancomycin (MICs of 512 and 1,024 micrograms/ml) were isolated from blood cultures in two compromised patients. These organisms were identified as Leuconostoc spp. Leuconostoc spp. are gram-positive cocci found in vegetables and dairy products; they had not been isolated previously from clinical specimens. The susceptibility of eight Leucon...
متن کاملMeningitis caused by vancomycin-resistant Leuconostoc sp.
A rare case of purulent meningitis caused by vancomycin-resistant Leuconostoc sp. is reported. The patient was treated successfully with penicillin G, and there were no neurological sequelae. We recommend that all gram-positive cocci isolated from cerebrospinal fluid and blood be fully identified so as not to confuse Leuconostoc spp. with more commonly isolated pathogens such as pneumococci and...
متن کاملCharacterization of six Leuconostoc fallax bacteriophages isolated from an industrial sauerkraut fermentation.
Six bacteriophages active against Leuconostoc fallax strains were isolated from industrial sauerkraut fermentation brines. These phages were characterized as to host range, morphology, structural proteins, and genome fingerprint. They were exclusively lytic against the species L. fallax and had different host ranges among the strains of this species tested. Morphologically, three of the phages ...
