Environment
Coagulation experiments conducted with polyaluminium chloride (PACl). Throughout the coagulation experiments the zeta potential and turbidity changes of cyanobacteria and algae were observed. The results showed that the zeta potentials of Synechococcus sp. and M. aeruginosa were positive at acidic condition, with a maximum of +12.16

Thawing of semen straws at 40oC for 30 S was suggested by Dhami et al. (1994); Vale (1997). Slower thawing rates have also been tried by Kumar et al. (1993); Ramakrishnan and Ariff (1994); Fabbrocini et al. (1995) and reported various suitable times and temperatures: 37oC for 30 S, 35oC for 30 S and 39oC for 30 S, respectively.
