Corynebacterium ihumii strain GD7(T) sp. nov. is proposed as the type strain of a new species, which belongs to the family Corynebacteriaceae of the class Actinobacteria. This strain was isolated from the fecal flora of a 62 year-old male patient, as a part of the culturomics study. Corynebacterium ihumii is a Gram positive, facultativly anaerobic, nonsporulating bacillus. Here, we describe the...

A taxonomic study was performed on strain D7015T, which was isolated from coastal sediment close to a coal-fired power station in Qingdao, China. Cells of strain D7015T were Gram-positive, non-motile, diphtheroid rods that grew in the presence of 0-8% (w/v) NaCl and at 4-37 degrees C, with optimum growth at 1% (w/v) NaCl and 30-32 degrees C. The DNA G+C content was 65.0 mol%. The major fatty ac...

Twenty unidentified Gram-positive, rod-shaped organisms were recovered from the cloacae of apparently healthy wild penguins (Spheniscus magellanicus) and subjected to a polyphasic taxonomic analysis. On the basis of cellular morphology and biochemical criteria, the isolates were tentatively assigned to the genus Corynebacterium, although the organisms did not appear to correspond to any recogni...

In recent years we can observe an increasing number of publications describing different incidents of infections, where species of Corynebacterium are isolated as the etiological factor of infection (Anderson et al., 2008; Campanile et al., 2009; Chiner et al., 1999; Dela et al., 2008; Fernandez-Roblas et al., 2009; Funke et al., 1997a; Funke et al., 1997b; Lagrou et al., 1998; Otsuka et al., 2...

Two small polypeptides, PorA and PorH, are known to form cell wall channels in Corynebacterium glutamicum and in Corynebacterium efficiens. The genes coding for both polypeptides are localized in close proximity to one another between the genes coding for GroEl2 and a polyphosphate kinase (PKK2). In this study, we investigated the relationship of PorA and PorH to one another. The results sugges...

Corynebacterium terpenotabidum Takeuchi et. al 1999 is a member of the genus Corynebacterium, which contains Gram-positive and non-spore forming bacteria with a high G+C content. C. terpenotabidum was isolated from soil based on its ability to degrade squalene and belongs to the aerobic and non-hemolytic Corynebacteria. It displays tolerance to salts (up to 8%) and is related to Corynebacterium...

Three Gram-positive, rod-shaped, oxidase-negative, non-spore-forming, non-motile bacteria (KSS-3Se(T), KSS-4Se and KSS-10Se) were isolated from a coolant lubricant. 16S rRNA gene sequence analyses revealed almost identical sequences, with only a few (<10 positions) differences for these three isolates. Comparisons showed the highest similarities to Corynebacterium pilosum NCTC 11862(T) (97.6 % ...

Three glutamic-acid-producing coryneform strains were isolated from soil and vegetable samples. Chemotaxonomic investigations indicated that these strains belonged to the genus Corynebacterium. Phylogenetic studies, based on 16S rDNA analysis, demonstrated that the three strains formed a distinct cluster within the genus Corynebacterium and that their nearest relatives were Corynebacterium glut...
