Examples include: Nutrient Broth, Blood agar, and chocolate agar. Chemically Defined Media - ANSWER- Composed of precise amounts of pure chemical and generally not practical for routine laboratory use (invaluable in research) Selective Media - ANSWER- Inhibit the growth of unwanted organisms (allow o...

Student Name: Ashley Anderson. Access Code (located on the underside of the lid of your lab kit): AC-VRIKUTP. Pre-Lab Questions 1. What is the difference between chemically defined and chemically complex media? Give either a clinical or environmental research example for which each media type would be the most appropriate choice for culturing microorganisms. Chemically defined media is media where the exact chemical compositions are known and made with purified ingredients. This type of...

BIOS 242 Week 5 Assignment; Lab 9 of 14 Onsite; Food Safety. Lab 9: Food Safety Learning Objectives: To learn about effectiveness of hand washing To learn about cleaning produce To learn about appropriately storing foods GI infections occur due to contaminated food and water. Clean drinking water, washed produce, appropriate storage of food and simple personal hygiene habits such as hand washing help tremendously in reducing the incident of GI infections. In this lab, we will test the ef...

Growth media - nutrient-rich environment for isolating and culturing microorganisms, includes sugars, amino acids, and vitamins, also called nutrient broth, grows microbes in a suspension Lysogeny broth - most common nutrient broth, can grow a vast array of microbes, plates are yellow, non-selective and non-differential media, commonly used for growing e coli (easily produces recombinant proteins) Selective media - suppress growth of unwanted bacteria and encourage growth of desired microb...
