Contained Use (Greenhouse)
Status :
Ongoing
Cooperating Institution:
Supervising IBC:
Project Leader(s) :
Lilia M. Fernando
Andrew D. Montecillo
Ma. Theresa Jonna A. Atienza
Experimental Facility/Site:
BIOTECH-UPLB
Purpose / Objectives :

To determine the gene responsible for the AuNP production of PGPB through the aid of transposon mutagenesis

Biosafety measures:

1. Proper laboratory attire (lab gown, closed shoes, gloves, etc.) will be worn at all times.

2. The correct containers will be used in conducting transposon mutagenesis experiments.

3. The isolates and other materials will be handled carefully to avoid spills.

4. Work surface will always be sterilized before and after every activity.

5. The researcher will wash and disinfect her hands after working with the isolates and before leaving the laboratory.

6. Eating, drinking, smoking, handling contact lenses, applying cosmetics, and storing food for human consumption are not permitted in the laboratory.

7. All materials that were in contact with the isolates will be disinfected and/or decontaminated.

8. The cultures and containers will be decontaminated once the project has been terminated.

Executive Summary:

One of the most exciting fields in nanotechnology is the synthesis of nanoparticles. These nano particles have broad range of uses from medicine to cosmetics. The synthesis of gold nanoparticles (AuNPs) gained attention due to its use in the field of medicine. Biological synthesis of AuNPs using microorganisms allows the production of homogeneous and monodispersed AuNPs. Some plant growth promoting bacterial (PGPB) isolates were found to synthesize gold nanoparticles in the 10-100 nm size range. However, the genese and pathway for AuNPs synthesis is not yet elucidated.

This project will utilize transposon mutagenesis to determine the gene/s responsible for the gold nano particles (AuNPs) biosynthesis of PGPB. Other advanced molecular biology techniques will also be employed in the study. The study involves the insertion of the plasmid pRL27 containing Tn5 from Escherichia coli to a PGPB isolate through becterial conjugation. This will be followed by the characterization of the transconjugants and the wild type via AuNP production assay. Genomic DNA extraction and polymerase chain reaction of kanamycin resistance gene, and the transformation of E. coli and selected bacterial strains by electroporation will also be performed. All the experiments will be performed at the Nano-Biotech Information and Translational Laboratory (NBITRL) in BIOTECH-UPLB from November, 2016 to March, 2017.
