A cell of a bacterium or unicellular alga that is actively growing rather than forming spores. ‘These bacteria exist either as spores or as vegetative cells.’. ‘The pollen grain (male gametophyte) is a three-celled structure composed of two generative cells encased within the vegetative cell.’.

Spore-forming bacteria can survive conditions that eliminate vegetative cells. Many of these spore-formers are pathogens and/or cause spoilage. Both of these situations will result in economic losses.

Vegetative Cells. Vegetative cells are nonmotile and exhibit a variety of growth forms, from unicellular and globose or cylindrical to colonial and coenocytic, or filamentous.

Vegetative bacteria cells meaning

The vegetative cells of L. sphaericus are effective against Ae. aegypti larvae, meaning that it could be used in the biological control of these mosquito species. Since the L. sphaericus consortium was effective against temephos-resistant Ae. aegypti, vegetative cells could be an alternative to overcome insecticide-resistant populations. The vegetative cells of B. anthracis showed similar UV sensitivity to those of Burkholderia pseudomallei, Shigella sonnei, and a wild-type strain of Escherichia coli. Yersinia enterocolitica and Vibrio cholerae appeared more sensitive to UV and Salmonella typhi slightly more resistant to UV than E. coli. The sensitivity (at 254 nm) of all Vegetative bacteria are the bacterial cells that are metabolizing and undergoing binary fission. They are "alive" and replicating.
