Abstract

Abstract: The making of perfume from the combination Magnolia alba (M. alba) flower oil, Cananga odorata (C. odorata) and Mimusops elengi L (M. elengi) fixed with Pogostemon cablin oil (P. cablin) have been done. Essential oil of M. alba and C. odorata was distilled by water distillation and extraction essential oil of M. elengi flower using n-hexane evaporated solvent method. Composition perfume through organoleptic test obtained with a ratio of 4% v/v, 4% v/v, and 2% v/v for each essential oil M. alba, C. odorata and M. elengi. Antibacterial activity of the perfume and each of the volatile oil was performed by the disc diffusion method. Antibacterial activity test showed that perfumes were able to inhibit the growth of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) bacteria, but less active. Antibacterial activity of the perfume was more active against E. coli with an inhibitory zone of 8.3 mm and 39.81% inhibitory power than S. aureus bacterial 7.3 mm inhibition zone with 37.55% inhibitory power. Perfumes after storage for one, and two months had better antibacterial activity than before storage with an average inhibitory zone of 11-15 mm and inhibitory power of 50- 68,18%.

Abstract

The search for novel DNA Polymerases I, with higher fidelity and better polymerization rate, is essential to improve the Polymerase Chain Reaction method. A thermo-halophilic bacterium has been isolated from an undersea hot spring, dubbed Pria Laot Sabang (PLS) A strain. The 0.9 kb DNA Polymerase I gene fragments from the isolate were amplified, sequenced, and identified. The fragments were part of the polymerization domain of the enzyme. Homological analysis of the gene sequence showed that the PLS A strain was closely related to Bacillus caldolyticusstrain XM. However, Swissprot structural analysis reveals that PLS A strain had high homology to Geobacillus stearathermophilus. Full sequence analysis is still needed to identify the species and evaluate the intact enzyme structure.
