Model Structure
On the outside, the cell wall of
gram-positive bacteria has a 20 to
80 nm thick murein layer (peptidoglycan), which is separated from the
cell membrane by the narrow periplasm. Gram-negative bacteria, on
the other hand, only have a 2 to 3 nm
thick murein layer, the outside of
which is covered in a thin lipoprotein
layer. However, both groups develop
an outer mucus layer (capsule),
which covers the cell in an even
thickness
Height: 22 cm., width: 36 cm., depth: 39 cm., weight: 4.3 kg
Cleaning and disinfecting your SOMSO Model:
Spray a rapid and effective water based
disinfectant for use on surfaces and wipe with a soft cloth.
