Pengaruh Sumber Karbon Terhadap Daya Antagonistik Bakteri Pseudomonas Pendar Fluor Terhadap Erwinia Carotovora
Abstract
This research was conducted to study antimicrobial stimulation of fluorescent
pseudomonad to inhibit Erwinia carotovora. We used several carbon sources to stimulate
antimicrobial substances from fluorescent pseudomonad that available to inhibit E.carotovora in vitro.
The results shown that mannitol 10% was the best stimulant agent to increase antagonistics of
fluorescent psudomonad againts E. carotovora. Also, mannitol increased antimicrobial substances
twohold compared with control without stimulant agent. Detection of antimicrobial substance using
TLC showed that only one antimicrobial was detected with retention factor (Rf) of 0,68. However,
identtification and characterisation of that substance is needed.
