Abstract
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.
