Summary:
A generally accepted, 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials has been shown to be incorrect by a team of scientists led by Donald Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State and a research professor in the Department of Chemistry and Biochemistry at Montana State University. The research, which will be published in the journal Science on Dec. 16, is expected to help scientists discover new ways of genetically engineering bacteria to manufacture biofuels -- energy-rich compounds derived from biological sources. Many textbooks, which cite the 44-year-old interpretation as fact, likely will be revised as a result of the new discovery.
Critique:
will the bifuel cost more or less once they find out if the certain bacteria can make energy?
Impact:
help the world be more eco-friendly.
