300833 Lecture Notes - Lecture 11: Basal Body, Cell Envelope, Flagellin
Document Summary
Filament: the filament is the longest and most obvious component of the bacterial. Flagella , it extends from the cell surface to the tip. The hook is made up of different protein subunits. Structure of a bacterial endospore and explain the differences between endospores and vegetative cells. Structure of bacterial endospore: the structure of a bacterial endospore consists of a core, Exosporium, coat, outer membrane, inner membrane , germ cell wall and a cortex. Vegetative growth and endospore comparison: vegetative growth: vegetative growth is the normal, continuous cycle of growth and division. Sporulation: sporulation contrastingly is a complex process that occurs in a highly organised fashion over several hours. Why bacterial endospores are of particular concern to the food industry. Bacterial endospores are very problematic for the food industry as it"s not impossible to always apply enough heat during food processing to kill spores. Bacterial spores caused food poisoning in many restaurants, hospitals and homes through meat dishes.
