Subject: Workshop on enzymes
"Enzymes and Their Targets for Conservators" (3 day workshop) Hal Erickson, Instructor Atlanta Art Conservation Center Atlanta, GA February 23-25, 2007 Presented by Southeast Regional Conservation Association (SERCA) with a grant from AIC $175 for SERCA or AIC members, $250 for non-members Register by January 10, 2007 Designed for conservators with varied backgrounds, this course does not require prior experience with specific instrumentation or techniques; however, it is assumed the participant has a basic understanding of and interest in the physical and chemical nature of archival and artifact materials. Included in this course is a chemistry refresher module covering the following topics: * Properties and solvation of molecular and ionic materials including solvation shells and surfactancy * Acidity and alkalinity in aqueous environments, and consequences for materials of biological origin * Structural proteins (e.g. collagen and fibroin); catalytic proteins (i.e., enzymes); lipids (e.g. fats and oils); carbohydrates (e.g. starches, cellulose, chitin, and related materials); and relevant aspects of the aging of these biomacromolecules. The three day workshop will focus on the safe and effective use of enzymes to digest adhesives and related residues. After the refresher course, topics covered will include the following: * The structure and activity of enzymes (e.g. amylases, proteases, lipases, and chitinase) * Enzymatic activity as related to pH and ionic balance * Spot tests for materials to be digested * Structures and vulnerabilities of adhesives and residues * Treatment approach and artifact safety-choice of the appropriate enzyme for the target and artifact * Pre-treatments that facilitate enzyme activity * Solvation strategies for the removal of enzymes and degradation products. A DVD containing Erickson's presentation of molecular biological basics to NARA's 2000 Deacidification Reconsidered conference will be available for those wishing to have a brief "pre-refresher refresher" on the basic types of structural biomacromolecules found in paper, textiles and adhesives.
