The "Enzymatic Processes and Enzyme Production" session focused on the manufacture and use of enzymes. The"IndustrialChemicals"sessionemphasizedrecentdevelop mentsintheintegratedproductionandscale-upofchemicalsfrombiologi cal rather than petrochemical routes. Special interest was on separation methods and their integrationintonew fermentation orhybrid processes. 35 oral presentations, a roundtable The technical program consisted of forum, two special topic discussions, and a poster session of 135 posters.
