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...

In the present study, synthesis, characterization, and the antibacterial activity of silver nanoparticles from native isolate of Corynebacterium glutamicum has been reported. Silver nanoparticles were synthesized by challenging the dried biomass of C. glutamicum with aqueous diamine silver ([Ag (NH3)2]+) containing 1 mM AgNO3. Synthesized silver nanoparticles (AgNPs) were characterized by ultra...

A new functional Corynebacterium glutamicum insertion sequence (IS) element, IS13655, was isolated using a suicide vector. The IS element was 1,293 bp in size and contained 26-bp imperfect inverted repeats (IRs) and 3-bp target site duplication as direct repeats (DRs). IS13655 harbored two ORFs with high similarity to the transposase of IS1206, an IS3 family element. IS13655 revealed relatively...

production of lysine by corynebacterium glutamicum (ptcc 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. for this purpose, ammonium sulphate was selected as a constant nitrogen source. the effect of different nitrogen sources was also investigated with glucose as a constant carbon source. the production of l-lysine was exam...

The biocatalytic efficiency of recombinant Corynebacterium glutamicum ATCC 13032 expressing the secondary alcohol dehydrogenase of Micrococcus luteus NCTC2665 was studied. Recombinant C. glutamicum converts ricinoleic acid to a product, identified by gas chromatography/mass spectrometry as 12-ketooleic acid (12-oxo-cis-9-octadecenoic acid). The effects of pH, reaction temperature, and non-ionic...

Chorismate mutase (CM) catalyses the rearrangement of chorismate to prephenate and is also the first and the key enzyme that diverges the shikimate pathway to either tryptophan (Trp) or phenylalanine (Phe) and tyrosine (Tyr). Corynebacterium glutamicum is one of the most important amino acid producers for the fermentation industry and has been widely investigated. However, the gene(s) encoding ...

Deletion and mutational analysis of the promoter P-dapA from Corynebacterium glutamicum was performed to identify regions and particular nucleotides important for its function. An extended -10 region and a stretch of six T's at positions -55 to -50 were found to be the most important elements in the promoter function. The results of mutational analysis of P-dapA are consistent with the conclusi...

The genus Corynebacterium represents one of the earliest described bacterial genera. Recently, we can observe an increasing number of publications describing different incidents of infections, where species of Corynebacterium are isolated as the etiological factor[1-6]. This genus was originally proposed for the causative organism of Corynebacterium diphtheriae (Lehmann and Neumann, 1896) for d...

Singularized cells of Pichia pastoris, Hansenula polymorpha, and Corynebacterium glutamicum displayed specific growth rates under chemically and physically constant conditions that were consistently higher than those obtained in populations. This highlights the importance of single-cell analyses by uncoupling physiology and the extracellular environment, which is now possible using the Envirost...
