“…TA can bind to proteins through hydrogen bonding and hydrophobic interactions and is often used as a natural compound to impart antibacterial properties to materials . Crucially, TA penetrates the cell wall of bacteria, reaches the inner membrane, and interferes with cell metabolism, leading to bacterial death. , A larger inhibition zone appeared against S. aureus because the antibacterial activity of TA was higher against Gram-positive bacteria than against Gram-negative bacteria, which have bilayered membranes …”
