They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane.. Gram-negative bacteria are found everywhere, in virtually all 2020-05-02 The vegetative cells of most bacteria, including food pathogens, spoilage bacteria, and the lactic acid bacteria used in vegetable fermentations, are readily destroyed by heating to 160°F (71°C), especially when the pH is low. Acid and low pH are also toxic to most bacteria. This is why vegetable fermentations are useful for food preservation. 2021-01-24 Characterization of radiation-resistant vegetative bacteria in beef.

When the environment becomes more favorable, the endospore can reactivate itself to the vegetative state. Most types of bacteria cannot change to the endospore form. Examples of bacterial species that can form endospores include Bacillus cereus , Bacillus anthracis , Bacillus thuringiensis , Clostridium botulinum , and Clostridium tetani .
