Abstract
Rosilene Welter investigated the use of enzymatic and photocatalysis to produce biodiesel. She developed an immobilized microbiocatalyst with high enzymatic activity, stability and re-usability. Likewise, she devised photocatalytic protocols that utilized various feed stocks, including waste cooking oil, and achieved high biodiesel yields.
