Bacterial Spores: Structure and Spore-Forming Bacteria
Bacterial spores are highly resistant, dormant structures (i.e. no metabolic activity) formed in response to adverse environmental conditions. As bacterial spores are formed within the parent cell, these are called endospores.
Bacterial Spore - an overview | ScienceDirect Topics
Bacterial spore is a resistant structure to unfavorable environmental conditions. Each cell produces only one spore and each spore germinate to one vegetative cell. The spore is just a part of the life cycle of spore forming bacteria under unfavorable conditions.
Bacterial Spore: structure, types, sporulation and germination
2017年7月25日 · Bacterial Spore: structure, types, sporulation and germination. Spore is metabolically dormant structure produced during unfavorable condition by the process called sporulation; Sporulation occur during late log phase or early stationary phase; Under favorable condition spores germinate to give vegetative cell. Size: 0.2 µm

2012年5月10日 · The structure and chemical composition of bacterial spores differ considerably from those of vegetative cells. These differences largely account for the unique resistance properties of the spore to environmental stresses, including disinfectants and sterilants, resulting in the emergence of spore-forming bacteria such as Clostridium difficile ...
Bacterial Spore - an overview | ScienceDirect Topics
Bacterial spores are extremely resistant and metabolically quiescent cell forms mainly produced by members of two genera of Gram-positive bacteria, the aerobic or facultative anaerobic Bacilli and the strictly anaerobic Clostridia (Fritze, 2004). These organisms share the ability to form a spore from a vegetative cell in response to ...
