Effects of Heavy-Metal Stress on Cyanobacterium Anabaena flos-aquae

Abstract The influence of two metals, copper and cadmium, was studied on the growth and ultrastructures of cyanobacterium Anabaena flos-aquae grown at three different temperatures: 10°C, 20°C, and 30°C. The highest concentration of chlorophyll a was observed at 20°C and the lowest at 10°C. Both toxic metal ions, Cu2+ and Cd2+, inhibited growth of the tested cyanobacterium. Chlorophyll a concentration decreased with the increase of metal concentration. A 50% decrease in the growth of A. flos-aquae population, compared with the control, was reached at 0.61 mg l−1 cadmium and at 0.35 mg l−1 copper (at 20°C). Copper at all temperatures tested was proven to be more toxic than cadmium. At 3 mg l−1, the lysis and distortion of cells was observed; however, after incubation at 9 mg l−1 cadmium, most of the cells were still intact, and only intrathylakoidal spaces started to appear. Copper caused considerably greater changes in the protein system of A. flos-aquae than did cadmium; in this case, not only phycobilins but also total proteins were destructed. The aim of this study was also to identify the place of metal accumulation and sorption in the tested cyanobacterium. Analysis of the energy-dispersion spectra of the characteristic x-ray radiation of trichomes and their sheaths showed that cadmium was completely accumulated in cells but was not found in the sheath. Spectrum of the isolated sheath after treatment with copper exhibited only traces of the metal, but isolated cells without a sheath showed a high peak of copper.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
