Protective perfumes: the role of vegetative volatiles in plant defense against Airborne induction and priming of plant resistance to a bacterial
This paper presents quantitative fluorescence measurements from vegetative cells of the bacteria Escherichia coli (gram negative) and Bacillus subtilis (gram positive). Dispersed fluorescence spectra are recorded from 270 to 560 nm .
This bacterium exists in two forms: vegetative cells and spores. The vegetative cells of Clostridium botulinum are killed by oxygen. The spores allow the organism to survive when nutrients are low and/or oxygen levels are too high. The vegetative cells produce the toxin. This toxin is very potent. 2006-08-27 This stain is designed to distinguish vegetative cells of bacteria (active, living cells) from endospores. A bacterial smear is first placed over a water bath and the stain malachite green is applied.

Next the peptidoglycan cortex forms between the two layers and the bacterium adds a spore coat to the outside of the forespore. Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded. This bacterium exists in two forms: vegetative cells and spores. The vegetative cells of Clostridium botulinum are killed by oxygen. The spores allow the organism to survive when nutrients are low and/or oxygen levels are too high.
When the favorable condition prevail, (i.e. availability of water, appropriate nutrients) spores germination occurs which forms vegetative cells of pathogenic bacteria.
Cell shape is generally characteristic of a given bacterial species, but can vary depending on growth conditions. Some bacteria have complex life cycles involving the production of stalks and appendages (e.g. Caulobacter) and some produce elaborate structures bearing reproductive spores (e.g. Myxococcus, Streptomyces).

The cell which produces spores and which is metabolically active is known as a vegetative cell. Vegetative cell grows rather than producing spores. It contains a high amount of water content, and it is not resistant to harsh environmental conditions. Unlike spores, vegetative cells are susceptible to disinfectants, heat, chemicals, radiation, etc.
