ABSTRACT — The objective of this research was to determine antimicrobial activity against Grampositive bacteria represented by the following reference strains : Streptococcus pyogenes ( ATCC 19615 ), Staphylococcus aureus ( ATCC 25923 ), Listeria monocytogenes ( ATCC 19114 ), Bacillus cereus ( ATCC 10876 ), and Clostridium perfringens ( ATCC 13124 ) of three extracts of Thuja occidentalis smaragd , Thuja occidentalis golden smaragd , and Thuja occidentalis fastigiata . The plant material used was obtained through the pruning of live fences . The method of microdilution in a culture medium , which is one of the simplest methods , was used for testing antimicrobial sensitivity . Following our research , we can conclude that the extracts inhibit Gram-positive bacteria , especially at the first concentration tested . The demonstrated effect of Thuja occidentalis golden smaragd recommends it as a possible candidate for natural products with antimicrobial activity . Our discoveries might pave the way for utilising Thuja occidentalis golden smaragd blends in diverse applications , including developing dermatological treatments for bacterial infections and the food industry .
