Yet others use organic carbon as carbon source and inorganic molecules for energy. Some bacteria produce endospores. This is a specialized structure which gives the cell resistance to environmental stresses. The actinomycete group of bacteria produce various asexual reproduc-tive spores. Generally, bacterial reproduction is asexual and occurs by binary fission resulting in identical daughter cells.
Many bacteria produce a capsule.
This is generally mucoid in nature and consists of lipids and polysaccharides. The capsule provides protection for the organism in certain environments.
