Asid piroligneous (PA) yang merupakan cecair yang terhasil daripada kondensasi wap dan gas yang terbebas semasa pembuatan arang kayu di kilang arang di Kuala Sepetang, Perak telah digunakan dalam kajian ini. Asid piroligneous ini dipekatkan dengan menggunakan alat pemeruap berputar pada 80°C kepada satu per sepuluh (1/10) isipadu asalnya memberikan cecair asid piroligneous pekat (CPA). Ujian awal aktiviti antimikrobial menunjukkan PA dan CPA mempunyai ciri-ciri antimikrob terhadap 14 spesies mikroorganisma yang diuji iaitu 10 spesies bakteria, 2 spesies yis dan 2 spesies kulat. Pyroligneous acid (PA) a liquid produced from the condensation of vapours and gases escaped during the production of charcoal in charcoal village Kuala Sepetang, Perak was studied in this research. This PA was concentrated to one tenth of its original volume at 80°C using rotary evaporator and resulted in concentrated pyroligneous acid (CPA). Antimicrobial screening of PA and CPA showed that they possessed the antimicrobial properties against 14 microbial species i.e. 10 bacterial species, 2 species of yeasts and 2 species of fungi.
