  journal={Antonie van Leeuwenhoek},
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 and 17 nm to the peptidoglycan. Knob-like surface structures previously observed in freeze-fracture… CONTINUE READING
