| dc.description.abstract | Ralstonia solanacearum is one of soil pathogen bacteria that attack horticulture plant. Chemical pesticides are used commonly to control bacteria. Using chemical pesticides continously can give negative effect for living things and the evironment. Some soil microbes produce antibacterial compounds. This study aimed to test the potential of peat land microbes at Rimbo Panjang Kampar to inhibit Ralstonia solanacearum. This study used agar disk method to calculate the ratio activity between the inhibition zone and the colony diameter (Z/K) and then grouped into high, medium and low criteria. Twenty isolates of fungi that produced antibacteria against Ralstonia solanacearum consisted of genus Penicillium and Trichoderma. Isolate RPL2-29 (Penicillium) had the highest ratio (2.12) and isolate RPL2-38 (Penicillium) had the lowest ratio (1.14). Eleven isolates of actinomycetes that produced antibacteria consisted of Streptomyces, Micromonospora while 2 isolates has not been unidentified.Isolate RB3S51 (Streptomyces sp.) had the highest ratio (2.87) and RB3S57 (Streptomyces sp.) had the lowest ratio (1.29).The high criteria was dominated by actinomycetes isolates of the genus Streptomyces. Isolate RB3S51 (Streptomyces sp.) had the highest ratio (2.87) and the lowest ratio of fungal isolates RPL2-38 with ratio 1.14. Based on the characterization, the fungi were classified into the genus Penicillium | en_US |
