Two corynefonn organisms (A 1082 and A 1062) isolated from the skin mucus of Arctic cod, are described in detail. Strain A1032 may be a new species; strain A 1062 is a strain of Corynebacterium erythrogenes. Three carotenoid pigments, all with very similar absorption spectra, were found in both strains. Two of these pigments were identified as neoxanthin and sarcinaxanthin. "he third pigment ha...

Cellular fatty acid (CFA) compositions of 561 asporogenous, aerobic gram-positive rods were analyzed by gas-liquid chromatography as an adjunct to their identification when grown on blood agar at 35 degrees C. The organisms could be divided into two groups. In the first group (branched-chain type), which included coryneform CDC groups A-3, A-4, and A-5; some strains of B-1 and B-3; "Corynebacte...

Corynebacterium callunae DSM 20147(T) is a member of the genus Corynebacterium which contains Gram-positive and non-spore forming bacteria with a high G + C content. C. callunae was isolated during a screening for l-glutamic acid producing bacteria and belongs to the aerobic and non-haemolytic corynebacteria. As this is a type strain in a subgroup of industrial relevant bacteria for many of whi...

Systems metabolic engineering is a multidisciplinary area that integrates systems biology, synthetic biology and evolutionary engineering. It is an efficient approach for strain improvement and process optimization, and has been successfully applied in the microbial production of various chemicals including amino acids. In this review, systems metabolic engineering strategies including pathway-...

L-citrulline plays important roles in many physiological processes, and its application range is expanding rapidly. Corynebacterium glutamicum strains have the potential to be efficient producers. In this study, we performed optimization of biosynthesis operon C. ATCC13032 for production. Chromosomal integration integral argBEc gene from Escherichia coli (encoding natively insensitive N-acetylg...

We report the case of a 32-year-old woman who presented upon returning from India with cutaneous ulcers on the feet and pharyngitis. Microbiological testing showed the causative organism to be a toxigenic strain of Corynebacterium diphtheriae. She was treated successfully with penicillin and diphtheria antitoxin. This case emphasises the importance of maintaining a high index of suspicion for s...

objective: erythrasma is a chronic superficial infection of the intertriginous areas. most laboratories use methylene blue stain and 10% koh smear to identify corynebacterium minutissimum (c. minutissimum) by direct observation of filamentous bacilli. occasionally atypical forms can be seen that create problems in diagnosis. this study aims to use the polymerase chain reaction (pcr) method in o...

We present here the complete genome sequence of Corynebacterium pseudotuberculosis strain 12C, isolated from a sheep abscess in the Brazil. The sequencing was performed with the Ion Torrent Personal Genome Machine (PGM) system, a fragment library, and a coverage of ~48-fold. The genome presented is a circular chromosome with 2,337,451 bp in length, 2,119 coding sequences, 12 rRNAs, 49 tRNAs, an...

A total of 102 strains received as Corynebacterium 'group JK' were characterized by SDS-PAGE of their whole-cell proteins. Numerical taxonomy based on the protein pattern absorbance profiles indicated that 91 of the strains formed a cluster. Seventy strains isolated in the UK were identified as group JK, indicating the increasing detection of this group as opportunistic pathogens. Fine differen...

An organism resembling Corynebacterium striatum was isolated from the blood of a patient with acute aortic valvular insufficiency and no history of valvular heart disease. At autopsy, histopathologic examination of the aortic valve revealed pleomorphic gram-positive bacilli and destruction of valvular tissue. Our isolate differed from other nondiphtherial corynebacteria, including the type stra...
