Accomplishments & Reports: Studies of Bacterial EctoenzymesJames Christian and David Karl Extensive studies of the bacterial ectoenzymes leucine aminopeptidase and α- and β- glucosidase were undertaken on PD94-12 using the method of fluorimetric substrate analogues (4-methylumbelliferone (4MUF) and β-naphthyamine derivatives) pioneered by Hoppe (1983). In addition to water column sampling in concert with other measurements made routinely on this cruise, we focused particularly on three areas:
