Isolasi Dan Karakterisasi Parsial Mikroba Dari Tanah Tanaman Kelapa Sawit (Elaeis Gueneensis Jacq.) Di Kecamatan Kandis
ABSTRACT
The presence of microbes in the soil (bacteria, fungi and actinomycetes) is very much found starting from the top layer of soil to the bottom layer of soil. The number of populations and microbial activity in the soil can be an indication of soil fertility, one of which is in oil palm plantations. Oil palm plantation soil has environmental characteristics that support microbial growth and has the potential to be taken and used as a material to search for beneficial microbes. Soil microbes (bacteria, fungi, and actinomycetes) have the ability to provide nutrients in the soil, break down organic matter, promote plant growth, and act as biological agents to control pests and plant diseases. The purpose of this study was to isolate and characterize partial microbes found in oil palm plantation soil with different plant ages in Kandis District, Siak Regency. Observation of microbial colonization was carried out macroscopically and microscopically using Nutrient Agar (NA) medium, Potato Dextosa Agar (PDA) medium and Starch Casein Agar (SCA) medium. The results of this study obtained 29 isolates (17 bacterial isolates, 12 fungal isolates and none of the isolates from actinomycetes) with various macroscopic and microscopic characteristics.
Keywords: Bacteria, Fungi, Actinomycetes, Isolation, Characterization.
