Pengaruh pH terhadap Produksi Antibakteri oleh Bakteri Asam Laktat dari Usus Itik
Abstract: This study aimed to
determine the effect of pH on the production of antibacterial by lactic acid
bacteria. This study uses a completely randomized design factorial 3X 5 (3 X 5
treatment of bacterial isolates pH) with three replications. The first factor
consisted of pH 4, pH 5, pH 6, pH 7, pH 8, and the second factor that isolates
B2, B7, B8, whereas the parameters consists of a clear zone. The amount of
production is determined by the size of the diameter of antibacterial
inhibition zone against Salmonella sp. Differences in the production of
antibacterial determined based on the results of analysis of variance. The
treatment significantly further test BNT at 5% level. The results showed that
the effect of media pH test based on the potential for the production of
antibacterial effect. The diameter of the largest clear zone produced by B7
isolates at pH 6 was 17.2 mm, 17.1 mm B8 and B2 at pH 7 at 16.7 mm. The
smallest diameter of the clear zone produced by B8 at pH 4 was 15.1 mm, B2 at
pH 6 there is a clear zone of 12.7 mm and isolate B7 at pH 5 of 11.5 mm
