accidentally by Sir Alexander Fleming in 1928 at St. Mary’s hospital in London when he forgot to clean a Petri dish before leaving on vacation. Fleming’s experimentation with the left-behind mold led him to discover its dissolving effects on the Staphylococcus aureus bacterium. Through further trials he discovered that a pure culture of the mold effectively killed the harmful bacteria. 3) The Human Genome Project The crusade to map all human genes began in 1990 and was completed in 2003.

Chromatographic separation of the leaf ethanol extract by Erasto et al. (2006) yielded vernolide and vernodalol. The compounds exhibited a significant bactericidal activity against the Gram-positive bacteria (B. cereus‚ S. epidermidus‚ S. aureus‚ M. kristinae and Streptococcus pyrogens) while no activity

CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms
