Thank you any other gram as S aureus and other gram t bacter

any other gram as S. aureus and other gram t bacteria do not have membranes part of their cell walls; their cell walls contain riboic acid, which has a positive charge, and part of it is embedded in the LPS.

Solution

The statement is false on 2 places. First of all, gram + bacteria have teichoic acid as part of the cell wall not riboic acid. Secondly, the gram positive bacteria do not have LPS. LPS i.e. lipopolysachcharide is present only in Gram negative bacteria.
