Seleksi Dan Uji Antibakteri Aktinomisetes Asal Tanah Gambut Rimbo Panjang Kampar Riau Terhadap Escherichia Coli Dan Salmonella Typhi
Actinomycetes is one of microorganisms that can be used as a natural antibiotic. Metabolites produced by actinomycetes have antagonistic activity on bacteria, therefore it can be used as antibacteria. The purposes of this study were to select and test the antibacterial activity of actinomycetes isolated from peat soil in Desa Rimbo Panjang Kabupaten Kampar Riau to inhibit the growth of Escherichia coli and Salmonella typhi. This study was conducted from December 2013-January 2014 at the Microbiology Laboratory, University of Riau. Serial dilutions and pour plate method used for isolation of actinomycetes while agar disk method used for antibacterial test. The result found a total of 24 actinomycetes isolates, 10 isolates inhibiting E. coli and 16 isolates inhibiting S. typhi. The inhibition zone diameter of E. coli and S. typhi were 8,3 to 16,9 mm and 7,8 to 12,9 mm, respectively.
