Research Question: How does increasing the concentrations of Dettol Antiseptic Liquid from 0% to 100% affect the growth of Escherichia coli bacteria on the agar plates? Hypothesis: As the concentration of Dettol Antiseptic Liquid increases the inhibition of bacterial growth around the antiseptic disks also increases. Variables: |Type of variable

In a study by Karim‚ Asma and Kamal et al.‚ (2016) in vitro antimicrobial activity of Sudanese Cucumis melo L. fixed oil was investigated. Agar cup diffusion assay was performed against two fungal species (Candida albicans and Aspergillus niger)‚ two gram positive bacteria (Staphylococcus aureus and Bacillus subtilis) and two gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa).

REVIEW OF RELATED LITERATURE This investigatory project aims to make use of rambutan peeling extracts that is high in phenolic compounds such as tannin and saponin that exhibits antioxidant activity and antibacterial activity against pathogenic bacteria. Although the seeds contain such compounds the peeling exhibit greater amount of the said compounds. Rambutan is a very popular fruit cultivated in the Philippines and it is eaten in large amounts. The rambutans rind is quickly discarded and

Chapter One INTRODUCTION Herbal medicines tend to look primitive and unscientific when compared to synthetic (conventional) drugs‚ which are thought to be more reliable than those made from plants. Herbal medicine is still the mainstay of about 75-80% of the world population‚ mainly in the developing countries for primary health care (Kamboj‚ 2000). This is primarily because of the general belief that herbal drugs are without any side effects‚ besides being cheap and locally available. The
