B I O F U M I G A T I O N Glucosinolate hydrolysis Glucosinolates are organic anions possessing a thioglucose moiety, a sulfonated oxime, and any one of a variety of aliphatic or aromatic R groups. At least 120 structurally different glucosinolates have been identified in 16 different families of angiosperms. Although glucosinolates themselves possess limited biological activity, enzymatic degradation by thioglucoside glucohydrolase (E.C. 3.2.3.1), or myrosinase, results in the formation of a number of compounds including isothiocyanates, nitriles, SCN-, oxazolidinethione, epthionitriles, and organic thiocyanates. The products formed from any one glucosinolate are controlled by both the chemistry of the glucosinolate itself as well as reaction conditions such as pH, Fe2+ concentration, and the presence of specifier proteins and coenzymes. Much of our research has focused on identifying and quantifying the biologically active molecules produced by mustard and rapeseed tissues once they are incorporated into soil. Our most recent work showed that SCN- is produced from the primary glucosinolate in Sinapis alba meal by way of a unstable isothiocyanate intermediate.
