Pemencilan dan pencirian bakteria asid laktik daripada jeruk bambangan yang memberikan aktiviti antimikrobial
Published 2011“…Ujian sensitiviti antibiotik bagi bagi 56 isolat BAL melalui ujian penyaringan teknik penyerapan lubang menunjukkan hanya 12 isolat BAL menunjukkan sensitiviti terhadap bakteria patogenik yang diuji dan selepas peneutralan pH dan penyingkiran H202 hanya 3 isolat BAL menghasilkan zon perencatan pada pH 5.5 iaitu Lactobacillus plantarum (Lab40) sebanyak 8.3mm, Lactobacillus plantarum 1 (Lab 57) sebanyak 9.7mm dan Lactobacillus pentosus (Lab 50) sebanyak 9.1mm. pH memberi kesan yang nyata terhadap aktiviti antimikrobial dimana pada pH menghampiri neutral tiada perencatan bakteria patogenik yang diuji dicatatkan. …”
