Abstract
ABSTRACT
Pitrianty Satura.2015.Research had titled "Potential Test Antimicrobial Endophytic Fungi On the Roots of Rice (Oryza sativa)". Biology Department. Faculty of Mathematics and Natural Sciences. State University of Gorontalo. Supervisor I Prof. Dr. Ani M. Hasan, M. Pd, Supervisor II Dr. Jusna Ahmad, M.Si.
The objectives of study are to know the potential of endophhyte mold in roots of rice as manufacture of antimicrobial. This methodology of research used Descriptive method. The technique of collected the data are secondary metabolite produced seven isolates was result of test drag power in bacteria. That's result are Eschericia coli and Staphyloccocus, to know there are potential as a manufacture of antimicrobial. And the technique analyze of the data in this research are to measure the drag zone formed. Based on the test results of drag power, seven isolates there are A, B, C, D, E, F, G, capable of inhibiting Staphylococcus aurous bacteria growth with a diameter drag zone amounted to 12.6, 11.3, 11, 10, 10.3, 22.3, 9.3 mm and includes a strong category whereas isolates A, B, C, D, E, F, G, is able to inhibit the growth of bacteria Eschericia coli. Drag zone diameter of 7.6, 7.1, 7.2, 7.3, 8, 7, 8 mm and include the category of being. Positive control of streptomycin are able to inhibit the bacteria S.aureus and E. coli resistance area with a diameter of 20 mm and 20 mm. Based on the results of the study it can be concluded that at the root of rice plant (Oryza sativa) can be found 7 isolates mold endophyte can produce antimicrobials, but drag the resulting zone is the zone of partial drag.
Key words: Endophyte, Mold, Root of Rice Plant, Antimicrobial.
