Efficacy of araçá extract in reducing biofilms on teat cup linings
Abstract The objective of this work was to evaluate the efficacy of araçá (Psidium cattleianum) fruit extract in removing Staphylococcus aureus and Staphylococcus epidermidis biofilms from teat cup liners. New and used rubber liners were tested. Biofilm formation and removal were evaluated using a standardized protocol. The surface of the teat cup liners was analyzed with scanning electron microscopy. The used liners had a rougher surface, which promotes biofilm growth. The araçá extract outperformed sodium hypochlorite, being up to 21 times more effective in reducing biofilms on the used liners. Therefore, araçá extract shows potential as a biodegradable alternative for removing biofilms from teat cup liners.
