Abstract


Streptomyces is a gram-positive bacterium of the Actinomycetes group. These bacteria are known as beneficial bacteria in human life, both for humans themselves and for plants. The secondary metabolites of Streptomyces can be used as an antibacterial, antifungal, insecticide for plants and as an anthelmintic for humans. This research is motivated by the absence of research that discusses Streptomyces sp in the plant rhizosphere of the Liliaceae tribe in the Sumber bening village area. So that researchers are interested in doing this research. This study aims to determine the diversity of Streptomyces sp in the soil rhizosphere of Liliaceae plants in the Sumber Bening area. This study uses the Research and Development method. The study was conducted by isolating Streptomyces sp from the Rizosphere of three plants of the Liliaceae tribe, namely shallots (Allium cepa), Onions (Allium fistulosum) and Kucai (Allium schoenoprasum L) using YPGA medium (Yeast Peptone Dextrose Agar) and pouring down isolation techniques. After the isolates are obtained, the isolates will be purified by means of a scratch technique. Pure Streptomyces sp isolates were identified based on their morphological characteristics both microscopically and macroscopically. The results showed that there were 11 species of Streptomyces sp found in three Liliaceae plant rhizosphere with 6 species found in the onion rhizosphere, 3 species found in the leek rhizosphere and 2 species found in the rhizosphere of chives. There are Streptomyces griseourubiginosus, Streptomyces albovinaceus, Streptomyces griseus, Streptomyces albohelvatus, Streptomyces viridaris, Streptomyces hirsutus, Streptomyces nigrescens, Streptomyces herbaricolor, Streptomyces aureofaciens, Streptomyces nigrogriceolus,dan Streptomyces albolongus.
