摘要：
Chlorophyllase (Chlase) activity measured as the in vitro degradation of chlorophyll (Chl) was variably enhanced by various heavy metals (Cd2+, Pb2+, Mn2+, Co2+, Ni2+ and their mixture). The enzyme activity on Chl a was higher than that on Chl b. Chlase isolated from chlorella fusca or Kirchneriella lunaris responded differently to the heavy metals. The inclusion of Ca2+ in the assay media affected the enzyme activity. While some concentrations were stimulatory, others were inhibitory depending on particular heavy metal, the algal species, and the Chl a or b.
