Inoculums Preparation Primary isolation was initiated by nutrient agar plating and subsequently transferred to selective media like Pseudomonas Isolation Agar‚ MacConkey Agar and EMB agar for better isolation. Using sterile inoculation loop colonies of the test organism are transferred to 5ml of sterile nutrient broth and incubated at 37 0C overnight for 24hrs. Then this bacterial

Two methods were employed for propolis activity evaluation; firstly by agar well diffusion method using 40µl of propolis extracts and ethanol 70% as the solvent control per well against tested bacteria and fungus and more commonly used antibiotics were used in comparison to propolis samples. The second method was employed by measuring

active transport? What is passive transport? How is osmosis related to diffusion? How can we demonstrate active transport? How can we demonstrate Brownian movement? How can we demonstrate diffusion (2 ways)? How can we demonstrate osmosis (3 ways)? In terms of relationships between substances‚ how can we define “hypertonic”‚ “isotonic”‚ and “hypotonic”? What is the relationship between the size of a molecule and its rate of diffusion? ____________________________________________________________________________

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
