Vegetative cells of bacteria were first shown to be inactivated by pressures above about 100 MPa (MegaPascals) more than 100 years ago by Hite (1899), while bacterial spores were shown to be much more resistant, surviving pressures above 1200 MPa (Larson et al., 1918; Basset and Machebouf, 1932). 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. Ø They develop into an active vegetative cell. Examples of bacteria producing endospores: Aerobic endospore producing bacteria: Bacillus subtilis, B. megaterium, B. anthracis (cause Anthraxes).
An example of a spore forming bacteria is Bacillus anthracis, which is the agent of anthrax. Image of page 2.

Bacteria can form endospores in approximately 6 to 8 hours after being exposed to adverse conditions. The normally-growing cell that forms the endospore is called a vegetative cell.

Bacteria can form endospores in approximately 6 to 8 hours after being exposed to adverse conditions. The normally-growing cell that forms the endospore is called a vegetative cell.
Now I think you are asking about the endospores, since this is the most common. The vegetative cells of some bacteria may put them under a great deal of stress, especially in a certain environment wherein they are deprived of nutrients such as carbon and nitrogen. As a result, they produce inactive form-endospore. 2020-07-16

There are three ways by which the reproduction of bacteria occurs; those processes are (1) Vegetative, (2) Asexual and (3) Sexual.Let us go on a discussion: 1. Vegetative Reproduction of Bacteria: The vegetative reproduction of bacteria may be divided into two process : The Binary fission process and Budding process. One side then engulfs the other.
