spheroplast


Also found in: Dictionary, Encyclopedia, Wikipedia.

spheroplast

 [sfēr´o-plast]
a bacterial, yeast, or fungal cell that results after partial removal of the rigid cell wall, which forms a membrane-bound cell with a spherical shape that is dependent for its integrity on an isotonic or hypertonic medium.

sphe·ro·plast

(sfē'rō-plast),
A bacterial cell from which the rigid cell wall has been incompletely removed. The bacterium loses its characteristic shape and becomes round.
[sphero- + G. plastos, formed]

spheroplast

(sfîr′ə-plăst′, sfĕr′-)
n.
A bacterial cell whose cell wall has been degraded, often by the action of an antibiotic or a lysozyme, causing the cell to assume a spherical shape.
