title: Evaluation of Acacia nilotica (L.) del. and Casuarina equisetifolia forst. for tolerance and growth on microbially treated dyestuff wastewater.
abstract: Two tree species, Acacia nilotica (L.) Del. and Casuarina equisetifolia Forst., were tested for their tolerance and growth on dyestuff wastewater containing phenol, aniline, and methyl violet. The wastewater was treated microbially by using a culture of Pseudomonas alcaligenes in a fixed-film bioreactor. The plants were watered with untreated and treated wastewater and tap water (control) at the rate of 2 litre per plant per week. A. nilotica exhibited 100% survival with both untreated and treated wastewater, and growth (increase in height) was comparable to that of control plants. However, growth of C. equisetifolia was adversely affected. It exhibited 100% survival with treated wastewater but only 87% survival with untreated waste-water and the percentage increase in height was less with both treated and untreated wastewater. There was no effect on soil except for an increase in chloride content.
