    Improvement of cell growth and L-lysine production by genetically modified Corynebacterium glutamicum during growth on molasses J Ind Microbiol Biotechnol . 2013 Dec40121423-32. doi 10.1007s10295-013-1329-8.Improvement of cell growth and L-lysine production by genetically modified Corynebacterium glutamicum during growth on molasses J Ind Microbiol Biotechnol . 2013 Dec40121423-32. doi 10.1007s10295-013-1329-8.Abstract. To date the genus Corynebacterium comprises 88 species. More than half of these are connected to human and animal infections, with the most prominent member of the pathogenic species being Corynebacterium diphtheriae, which is also the type species of the genus.They may be straight or slightly curved with tapered and sometimes clubbed ends. One species Corynebacterium matruchotii has a whip-handle shape. Cells are usually arranged singly or in pairs, often in a V formation or in palisades of several parallel cells. Size 0.3-0.6 micrometers by 1.5-8.0 micrometers in length.

  • Ultrastructure Of The Corynebacterium Glutamicum Cell Wall

    The cell wall structure of the Gram-positive Corynebacterium glutamicum was evaluated by electron microscopy of thin sections after freeze-substitution and conventional fixation with glutaraldehyde. For the cell wall an overall thickness of approximately 32 nm was determined, with 8.5 nm corresponding to an outer layer, 6.5 nm to an electron translucent region ETR as found in mycobacteria ...The cell wall structure of the Gram-positive Corynebacterium glutamicum was evaluated by electron microscopy of thin sections after freeze-substitution and conventional fixation with glutaraldehyde.

This set-up avoids ethical problems of animal testing and has the additional advantage of lower costs. However, the influence of cell culture media on bacterial growth and metabolism is not considered or investigated in most cases. To address this question growth and proteome adaptation of .Jun 07, 2013 Two types of bacteria, Corynebacterium-diphtheriae-intermedius CDI, and Pseudomonas aeruginosa PA, were used. The collector-bacteria interaction was characterized by Fourier transform infra-red FTIR, frothing height and Zeta potential. The results show that the collector-bacteria interaction improves the flotation selectivity.
