16 Questions
What role do microorganisms play in the biosphere?
Microorganisms play a primary role in capturing energy from the sun and completing critical segments of the cycles of carbon, oxygen, nitrogen, and other essential elements for life.
What developments in the 1940s marked the birth of biochemical engineering?
Complementary developments in biochemistry, microbial genetics, and engineering ushered in the era of antibiotics.
How did biotechnology change in the 1940s?
Biotechnology began to change from empirical art to predictive, optimized design.
What has research in microbial genetics led to?
Research in microbial genetics has led to fundamental understanding of many of the controls and catalysts involved in complex biochemical syntheses conducted by living cells.
What foundation has recombinant DNA technology been built upon?
Recombinant DNA technology has been erected on the foundation of basic knowledge obtained from research in microbial genetics.
What is the focus of biochemical engineering?
Biochemical engineering focuses on engineering processes using catalysts, feedstocks, and/or sorbents of biological origin.
What did Schleiden and Schwann propose in 1838?
The cell theory
What is the diameter of most microorganisms?

What are the three main components found in even the simplest microorganisms?
Chemical reactors, information and control systems, and mass-transfer operations
What did observations with the electron microscope reveal about cells?
Two markedly different kinds of cells
What is the approximate diameter of most microorganisms?
0.1 mm or less
What is the study of living organisms too small to be seen clearly by the naked eye?
Microbiology
Test your understanding of the application of biotechnology concepts in biochemical engineering processes and the interactions of small living microorganisms with human activities. Explore the role of microorganisms in capturing energy from the sun and their biological activities in the biosphere.
