Abstract
The results revealed that salinity application (80 and 160 mM) after 20 minutes of inoculation significantly increased the yield of phycobilisome system. Increasing the time up to 40 minutes after inoculation will restore all parts of the photosynthetic system. After this time, cyanobacteria are able to rearrange and activate photosystem II, phycobilisome, and light-collecting complex. Athough, the behavior of cyanobacteria at salinity of 160 and 80 mM are opposite at times of 20 and 60 min. Compared to the untreated sample, pretreatment application within less than one hour changesin growth rate and attenuation at time intervals of 24 and 96 hours. The sample is capable of moderating the destructive effects of 160 mM for 20 minand 80 mMin 60 min treatments over 24 hours, which is not complete. The growth rate of up to 96 h in 80 mM for 20 min and 160 mM for 60 min treatments was higher than those without salinity. While,the system changes its pattern after 24 hours, the initial pattern remains unaffected by the time and salinity levels after this time
