Description
Byline: Abdul Rehman, Farah R. Shakoori and Abdul Rauf Shakoori* Abstract.- The multiple heavy metal resistant ciliates, Oxytricha fallax and Paramecium caudatum, isolated from industrial wastewater have been shown to be potential bioremediator of contaminated wastewater. The O. fallax showed tolerance against Zn2+ (17 ug/ml), Hg2+ and Ni2+ (18 ug/ml), and Cu2+ and Cd2+ (16 ug/ml). P. caudatum was found to tolerate Ni+2+,Cu2+, Hg2+, Zn2+, and Cd2+ at a concentration of 18, 15, 17, 15 and 14 ug/ml, respectively. The metal ions slowed down the growth of the ciliates as compared to the culture grown without metal stress. The reduction in cell population of O. fallax was 70% for Cd2+, 59% for Hg2+, 28% for Zn2+, 71% for Cu2+ and 70% for Ni2+ after 8 days of metal stress.
