► Pure gum presented higher activity against all studied bacteria with the exception of L. acidophilus. ► Crude gum presented activity only against Gram-positive bacteria and at higher CMI values than pure gum. ► Only crude gum presented bactericidal concentrations and only for Gram positive bacteri...
