Enzyme technology has been a recognised part of bioprocess engineering since its inception
in the 1950s and 1960s. In this article the early history of enzyme technology is discussed and
the subsequent developments in enzyme isolation, enzyme modification and process
technology are described. These creative developments have put enzyme technology in a
position of huge potential to contribute to environmentally compatible and cost effective
means of industrial chemical synthesis. Recent developments in protein modification to
produce designer enzymes are leading a new wave of enzyme application.
