Answer: It has peptidoglycan
Step-by-step explanation:
The kingdom Eubacteria is the domain of prokaryotic bacteria. These are unicellular and prokaryotic organisms. Their cell membrane is made up of lipids. The cell wall is made up of peptiodoglycan which gives rigidity to the cell wall. It gives the structural strength to the bacterial cell wall, gives the strength to the bacteria, and it will counteract the osmotic pressure develop in the cytoplasm.
Lactobacillus acidophilus possess the peptidoglycan in the cell wall this establishes its relationship with kingdom Eubacteria.
