Two specific examples of how microorganisms play a vital role in our lives: a. Nitrogen fixation: Certain bacteria, such as Rhizobium, convert atmospheric nitrogen into ammonia, which plants can use for growth. This process is essential for the fertility of soil Show more…

Staphylococcus aureus (underline genus and species names separately). Remember to capitalize the first letter of the genus and lowercase the first letter of the species: Staphylococcus aureus (all capital letters). Staphylococcus aureus (italicized genus and species). ONLY USE THIS IF YOU ARE TYPING. Do not try to write in italics. Is it okay to label your petri dish across the center of the plate? Why or why not? If not, where should you write your labelings? Is it better to label your petri dish on the lid or on the base of the plate? Why? Give an example of what could happen if you labeled your dish on the lid versus the base. In your own words, describe how to properly transfer bacteria from liquid culture (broth) to another liquid culture using aseptic techniques. Please begin from when you first enter the lab. You may do bullet points or numbering for this question.

Complete the following paragraph to describe the beneficial effects of microorganisms. The large number of bacteria living on or within your body are considered normal. Beneficial bacteria in the gut assist in the digestive process and produce vitamins, which humans are incapable of synthesizing for themselves. Beyond the benefits to us individually, microorganisms play an important role as decomposers that help to various organic and inorganic materials in ecosystems. Wastewater leaving many human households is cleaned by the metabolic activities of at water treatment plants. Microorganisms are important to us as participants in nutrient cycles but have also played an incredibly important role in the health industry. The first antibiotics discovered were naturally produced by bacteria or living in soil.
