The Responses of Carotenoids in Anabaena cylindrica to Single and Combined Metals of Nickel, Aluminum and Lithium
In the real polluted environment, the metals usually do not present in single pure form, but occur in mixture. Cyanobacteria are the most commonly available aquatic organisms in these environment, thus, there is a need to study the responses of carotenoids, a kind of antioxidant in cyanobacteria...

| 要約: | In the real polluted environment, the metals usually do not present in single pure form,
but occur in mixture. Cyanobacteria are the most commonly available aquatic
organisms in these environment, thus, there is a need to study the responses of
carotenoids, a kind of antioxidant in cyanobacteria towards combined heavy and light
metals. In this paper, Anabaena cylindrica was immobilized using agarose and exposed
to the different concentration of single and combined Ni, Al and Li for 2 hours. The
responses of carotenoids were determined using spectrophotometer at λ = 450 nm. The
result showed that immobilized A. cylindrica responded differently to the exposure of
single and combined metals. The cells were sensitive to single and combined Ni, Al and
Li within the detection range of 0.001 mg/L to 10.000 mg/L. The value of R2 indicated
the immobilized A. cylindrica responded in correlation to the concentration of the
metals. Thus, A. cylindrica has the potential to be used as bioindicator for detection of
single and combined metals. |
