  1. The effects of spices on the growth of microorganism Speakers:許耕嘉 陳詠暄 Teacher:許慶文

  2. Purpose of the study • Study the effects of different spices on inhibiting the growth of microorganism • Observe the growth of microbes to enable the identification and characterization of the microbes.

  3. Materials and Apparatus • Garlic • Hot pepper • Giant white radish • Ginger • Onion • Water • Petri dish • Blender • thermostatic container • SDA medium

  4. Methods • Chop up hot pepper into pieces in a blender • Put 3 grams of it into petri dish and mix it with 20g of the SDA medium • Put it in a thermostatic container and set the temperature at 30 degrees Celsius • Observe the growth of microorganism for 7 days • Change hot pepper into ginger, garlic, giant white radish, onion, and repeat the above steps

  5. The effects of spices on inhibiting the growth of microorganisms • Control group White radish Ginger Onion Garlic Hot pepper

  6. A closer look at the microorganisms 1. 2. Two types of microorganisms The white hypha appear

  7. Future study • Cultivate different kinds of microorganisms and study the effects that different spices have on each of them. • Explore the factors in the growth of microorganisms and investigate the strategies fungi use in face of competition • Analyze the chemical compositions of different spices and find the properties that inhibit the growth of microorganisms.

  8. Thank you for listening
