โœฆ Synopsis

The influnce of UV-B irradiance was examined on three strains of a cyanobacterium, Anacystis nidulam.

These include wild type A. nidulans (An) and strains resistant to cadmium (Cd? and cyanophage As-1 (As-1"). The results indicated that although, the UV-B radiation considered in the present study was damaging to all the three strains, As-1' offered some degree of protection from UV-BLas far as changes in chlorophyll, phycocyanin, "CO, uptake and photosynthetic O2 evolution were concerned. Cadmium resistant strain appeared to be most sensitive to UV-B among the three. The observations form the first report of UV-B effects on a metal resistant and a cyanophage resistant strain of cyanobacterium.

Photosynthetic properties of high temperature (38 "C) grown (HTG)' and low temperature (25 "C) grown (LTG) cells of /Inncysfi5 were examined. The results revealed several characteristic changes in the HTG cells which included light absorption property of the pigments, DCMU binding affinity of the ph
