As an entry-level microbiologist, your job is to work in a laboratory and use a variety of methods to test each microorganism, collect data, and use analysis procedures to explain the results. Microbiologists typically focus on science and research, but as an entry-level employee, your main job is to learn the various aspects of this job by participating in a variety of studies. Entry-level microbiologists often clean and sterilize equipment, manage lab inventory, document information, take notes, collect environmental samples, and complete other tasks as assigned. You may work unusual hours due to the extra time and attention required to get the job done. For example, you may be asked to work ten hours a day for four days each week.
