two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The initial streak-plate procedure was performed and placed in the incubator at 37◦C for 24-48 hours. Upon observing the growth on this plate‚ it is fairly obvious that one of the organisms is Serratia

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your
