We believe that Amyris's renewable base oil technology would be highly complementary to our existing product line and would provide our customers with access to high performing lubricants with reduced environmental impact," said John Schmidt, CEO of U.S. Venture.

Under the planned arrangement, Amyris would become the majority economic beneficiary of the joint venture.
