Bacteria and fungi share only a few similarities. Both are cells and microscopic. Both the bacteria and fungi also has a cell wall and a cell membrane. However, these two cells are very much different with respect to each other in many ways. Bacteria, in terms of the cell wall, has a soft cell wall in which the main component is peptidoglycan while for fungi their cell wall is mostly made up of chitin which makes it hard. Bacteria grows by binary fission while fungi grows through branching and elongation. Penicillium is a genus of a fungi with a major role in antibiotic production. Therefore Penicillium share the same characteristics with fungi.
