Many microbiologists work in laboratories.
They may isolate and grow organisms to better understand their relationship to human, plant and animal life, and how these microorganisms function in the production of vitamins, antibiotics, amino acids and alcohols . Microbiologists must be familiar with research techniques and complex lab equipment, and skilled in analytical techniques. Knowledge of computers is also useful when conducting experiments and interpreting computer-generated experimental and control data from modern research and diagnostic equipment. To become a licensed medical technologist in California, the graduate must take a state examination plus complete a one-year internship in the field. Various entry-level trainee positions in business and industry are available for graduates.
