Both Culture technicaly and chemically were unable to control this pathogen because they ability to form Clamydospore and to infect alternative hosts. The use of antagonistic bacteria such as Pseudomonas fluorescens and Bacillus subtilis were able to control plant pathogens both in rhizosphere or in phyllosphere because their ability to produce secondary metabolites such as siderophore, antibiotics, volatile substances, Cyanide acid, extracellular enzymes and phytohormones.

Both Culture technicaly and chemically were unable to control this pathogen because they ability to form Clamydospore and to infect alternative hosts.

The use of antagonistic bacteria such as Pseudomonas fluorescens and Bacillus subtilis were able to control plant pathogens both in rhizosphere or in phyllosphere because their ability to produce secondary metabolites such as siderophore, antibiotics, volatile substances, Cyanide acid, extracellular enzymes and phytohormones. The steps of research included exploration of antagonistic bacteria using Schaad methods, identification using Schaad, Palleron, Lelliot and Stead Methods.

Last steps were done by in vitro and in vivo tests. Fulltext in PDF. How to Cite. Jurnal Pengendalian Hayati , [S.

The essential oils were extracted by hydro-distillation using a Clevenger apparatus, and their antibacterial activities were measured by paper disk diffusion method. Significant differences in the antibacterial activity of essential oils, depending on plant source and on bacterial strain, were detected. The highest antibacterial activity against all tested bacteria was determined in TEO with a diameter of inhibition zone ranging from

The antagonistic rhizobacterium, Pseudomonas fluorescens strain LRB3W1, controls cabbage Fusarium yellows caused by Fusarium oxysporum f. Conversely, Serratia marcescens strain B2, known as a biocontrol bacterium, did not inhibit growth of F. Colonization of each bacterium in the cabbage rhizosphere was not influenced by the presence of the other bacterium. When bud-cells of the pathogen were treated with 2,4-diacetylphloroglucinol from strain LRB3W1 and fungal cell wall degrading enzyme from strain B2 simultaneously, an additive inhibitory effect was observed.

Continuous measurements of nitrous oxide isotopomers during incubation experiments. The revised manuscript was not accepted. N2 - Nitrous oxide N2O is an important and strong greenhouse gas in the atmosphere and part of a feed-back loop with climate. N2O is produced by microbes during nitrification and denitrification in terrestrial and aquatic ecosystems. The main sinks for N2O are turnover by denitrification and photolysis and photo-oxidation in the stratosphere. It has been demonstrated that nitrifying and denitrifying microbes have a different relative preference for the terminal and central position.
