Outline of Final Research Achievements

To evaluate an effect of anti-ribosome for microorganisms using LNA/DNA oligonucleotides, in vitro gene expression suppression experiments were conducted. From the experimental results, the designed LNA/DNA oligonucleotides had inhibitory effects depended on the dose concentrations, and the inhibitory effects were varied on its targeted site. So, as a next experiment pure bacterial cultures were used for inhibitory evaluations. From the results of growth inhibition experiments using E.coli strain AS19, little inhibitory effects were observed even thought higher concentration of LNA/DNA was used. Then, peptide added LNA/DNA oligonucleotides were designed and conducted the same experiment described above. The peptide added LNA/DNA oligonucleotides had a inhibitory effect in a certain extent but further research is needed to establish the microbial growth control technology for environmental engineering.
