| Abstract | ||
| The Blue green algae ( cyanobacterium ) Anabaena sp can fix aconsider able amount of atmospheric nitrogen and convert it to ammonium ( NH4 ) that can be used in protein synthesis and the food chain . This Anabaena was isolated from some pond near the coast of the Libyan ; and was tested for the effects of ultraviolet radiation( UV-B ; 285 ; 320 nm )on photosynthetic pigments ; growth and protein contents . Growth patterns of the cell treated with UV-B revealed that Anabaena sp was very sensitive to this radiation . complete killing of all cells occurred after 150 min of UV-B exposure .Pigments content; particularly phycocyanin , severely decreased following UV-B irradiation in all cells tested. The protein contents of the cells treated with UV-B showed a remarkable decrease with increase in UV-B exposure time . | ||
