A 4-h alpha-mannosidase test for identification of Arcanobacterium haemolyticum strains (n = 139) and differentiation of A. haemolyticum from Actinomyces pyogenes strains (n = 30) and other gram-positive rods was evaluated. Practically all A. haemolyticum strains (138 of 139) and the Listeria monocytogenes type strain were alpha-mannosidase positive, while all A. pyogenes strains and Corynebact...

In this work, we present the complete genome sequence of Corynebacterium ulcerans strain 210932, isolated from a human. The species is an emergent pathogen that infects a variety of wild and domesticated animals and humans. It is associated with a growing number of cases of a diphtheria-like disease around the world.

Here, we present the genome sequence of Corynebacterium ulcerans strain FRC11. The genome includes one circular chromosome of 2,442,826 bp (53.35% G+C content), and 2,210 genes were predicted, 2,146 of which are putative protein-coding genes, with 12 rRNAs and 51 tRNAs; 1 pseudogene was also identified.

A lipophilic coryneform bacterium isolated from a blood culture from a patient with signs of septicaemia was characterized by means of phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of cell-wall chemotype IV and short-chain mycolic acids, which are consistent with the genus Corynebacterium. The isolate was characterized biochemically by the very ...

Abstract Corynebacterium glutamicum is a microbial production host established in the industry 60 years ago. It mainly used for of feed and food amino acids. As C. strain development has been cutting edge since its discovery, it engineered plethora valuable products. This review will focus on recent developments engineering biotransformation fermentation processes towards flavor fragrance molec...

Confirmed isolates of nontoxigenic Corynebacterium diphtheriae in England and Wales increased substantially from 1986 to 1994. Ribotyping of 121 isolates confirmed in 1995 showed that 90 were of a single strain isolated exclusively from the throat; none had previously been identified in toxigenic strains from U.K. or non-U.K. residents. The upward trend in nontoxigenic C. diphtheriae probably r...

Bioremoval and bioreduction activities of hydrocarbon (diesel) isolation from environmental samples were studied by the activity of biosurfactant production, and calculating emulsification index, gravimetric, and FTIR analysis along with the estimation of bacterial biomass. Sample from soil near petrol, diesel pumps and water sample from Thesjaswini River near Padannakad, Kasaragod, Kerala, Ind...
