AKTIFITAS ANTIBAKTERI ACTINOMYCETES YANG DIISOLASI DARI TPA PUTRI CEMPO MOJOSONGO SURAKARTA
Abstract: Actinomycetes are
procaryotic organisms which are found in many habitats, such as: land, water,
and plant tissue. They have numerous function for the production of antibiotics
and diversity benders to pest and disease in plants. There were many
researchers explored new isolates that produces a compound of a novel
metabolites. One of them is screening actinomycetes isolated from the soil samples in Putri Cempo Landfill
in Surakarta. The isolates obtained by testing the bacterial activity with well
diffusion methods on the Gliserol-Yeast Extract media against four pathogenic
bacteria, namely: Ralstonia solanacearum, Bacillus subtilis, Escherichia coli,
and Staphylococcus aureus. In this research obtained 10 isolates of
actinomycetes, three of them have the ability to inhibit bacterial growth of R.
solanacearum, one isolate having the power to against Bacillus subtilis, one
isolates having the power of an abstruent against Staphylococcus aureus, and
two isolates capale in inhibiting the growth of E. coli. The antibacterial
activity were characterized from the inhibitory clear zone arround the ccolony
of Actinomycetes. These isolates were: PC 12, PC 13 dan PC 15. The inhibitory
clear zone were measured showed the power spectrum of the third of the isolates
are belong to the broad spectrum due to their diameter of the clear zone is
more than 8 mm.
