Referred to as resting cells in some books, myxospores are capable of surviving such harsh environmental conditions as UV light, high temperatures, and desiccation. Myxospores : A myxospore is a type of spore that is produced by myxobacteria/ Myxobacterates (slimy molds bacteria). They are also less resistant to tough environmental conditions and have a tough cell wall that is waterproof in place of the peptidoglycan layer found on the cell wall of bacterial endospores ![]() * Unlike endospores, cysts are non-reproductive cells. When conditions in the environment become unfavorable, the cells come together in a manner that allows them to survive. Sporosarcina ureae).Ĭysts: Cysts are a group of cells that join together in order to survive harsh environmental conditions. Bacillus anthracis) and Sporosarcina bacteria (e.g. They are typically produced by Clostridium (e.g. * Some filamentous cocci have also been shown to be capable of sporulation (producing endospores)ĭepending on the type of bacteria, four types of spores are produced.Įndospores: Endospores are the most common types of spores. Although some Gram-negative bacteria have been shown to be capable of producing spores, it's only a few species found in a few genera. These include aerobic Bacillus and anaerobic Clostridium species. in the genus Methylosinus)Ī majority of spore-forming bacteria are Gram-negative bacilli (rod-shaped). Exospores - Exospores are a type of spores that are produced outside the cell (e.g.Endospores - Type of spores that are produced within the organism (e.g.Microspores of plants (develop to formmale gametophyte).Megaspores of plants (female gametophyte). ![]()
