Toxicity of these xenobiotic compounds causes serious environmental problems. Bacillus sp ih1 was isolated from top cliff soil collected from Antarctica. The bacteria was first grown on Antarctic bacterial medium and later transferred to a minimal medium containing 2, 2, dichloropropionic acid as carbon source. It grew slowly in the minimal media in different concentrations of 10mM, 20mM, 30mM and 40mM of 2, 2 DCP. The best growth was observed in 20mM of 2, 2-DCP with doubling time 32hours. To monitor the degradation activity of the bacteria, halide ion assay was carried out to check the release of chloride ion. The best release of chloride was 0.657 mmol/L in 20mM of 2, 2-DCP. The bacteria was identification using 16S rRNA, genomic DNA extraction method and PCR amplification of 16S rRNA was performed using universal primers 27F and 1492R. Nucleotide blast (BLASTn) showed 97% similarity with bacillus sp. Results from biochemical tests further confirm the bacteria as bacillus sp. Using phylogeny.fr, sequences from nucleotide blast result were used to build a phylogeny tree based on neighbour to neighbour joining. 2016 Thesis http://eprints.utm.my/id/eprint/79326/ http://eprints.utm.my/id/eprint/79326/1/IsmailHarunaMFBME2016.pdf application/pdf en public masters Universiti Teknologi Malaysia, Faculty of Biosciences and Medical Engineering Faculty of Biosciences and Medical Engineering
