Abstract

Endophytic microbes are microbes that during their entire life cycle are in plant tissues. Actinomycetes is one of the endophytic microbes that produce secondary metabolites and can be found in the roots of onions. This study aimed to isolate, characterize and determine the growth rate of endophytic actinomycetes from Allium ascalonicum L. Palu cultivar. The isolation was done by spread plate method using SCA (Starch casein agar) medium, then purified and characterized their properties macroscopically (morphology of colony) and microscopically (morphology of cell) before it is determined their growth rate. Actinomycetes were isolated from the roots of onion namely, JO1, JO2, and JO3 which showed different in characters of each isolate. The result also showed that Actinomycetes growth rate was quicker on onion root extract than it was in SCB (Starch casein broth) medium. Based on that data, it can be concluded that endophytic Actinomycetes can be grown in onion root extract medium.
