Cell wall the cell membrane is the bacterial cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria, although L-form bacteria can be produced in the laboratory that lack a cell wall. The antibiotic penicillin is able to
Fungi of Australia came to Australia over the past couple of centuries brought no strong fungal cultural traditions of their own. Fungi have also been largely overlooked in the scientific exploration of Australia. Since 1788, research on Australian fungi, initially by botanists and later by mycologists, has been spasmodic and intermittent. At governmental level, scientific neglect of Australian fungi continues: in the country's National Biodiversity Conservation Strategy for 2010-2030, fungi are mentioned only once, in the caption of one illustration, and some states currently lack mycologists in their respective fungal reference collections. The exact number of fungal species recorded from Australia is not
