Running averages of leucine aminopeptidase activity in different sample fractions from September 1994 to December 1996 (A). Sample fractions: not filtrated (solid black line), <3 µm (dashed line), <0.2 µm (dotted line). Dependence of incubation temperature: calculated regression slopes of individual incubation experiments are shown (A, solid grey line) and exemplary, individual thermatron experiments from January 1995 (B, open circles) and June 1996 (B, filled circles)
