Mark the false statement regarding L forms of bacteria

L-forms bacteria/asL-phase bacteria Also known as L-phase variants or cell wall-deficient(CWD)bacteria Grow as spheroplasts or protoplasts. 1st isolated working on a culture of "Streptobacillus moniliformis." L forms may not initiate a disease however they can lead to bacterial persistence during antibiotic treatment = Recurrence of infection. It was used in Lister institute in London 2 types Unstable L-forms - Spheroplasts that are capable of dividing, but can reve to the original morphology Stable L-forms - L-forms that are unable to reve to the original bacteria. Although L-forms can develop from Gram positive as well as from Gram negative bacteria but during Gram stain, the L-forms always colour Gram-negative, due to the lack of a cell wall.
