Abstract
Heavy metals from industrial processes are of special concern
because they produced to water and accusing chronic poisoning in aquatic
animal. Heavy metals can damage the cell membranes, alter enzymes
specificity, disrupt cellular functions and damage the structure of the
DNA.
The concentration of copper, lead and cadmium in the wastewater
must be below that (1, 0.1 and 0.001) mg/ L, respectively.
Living and deeding biomass of actinomycetes used in
bioremediation heavy metals. The cell wall of actinomycetes species
generally contains three components, namely peptidoglycan, teichoic acid
and surface protein, which could play an important role in the biosorption
of metal ions.
Dead biomass more advantages than living biomass. These
advantages include their ease of treatment and no metal toxicity that can
result in cell death in live cells. Additionally, the dead biomass don’t
required supplementation with nutrients which can increase the biological
and chemical oxygen demands on the treated. The following results were
obtained from our results.
1- Sixty-six of different morphologically actinomycetes were isolated
from collected wastewater (27 isolates), sediment (14 isolates) and soil
samples (25 isolates) from Egypt
2- Living and dead biomass of actinomycetes were screened for
biosorption of Cu2+, Pb2+ and Cd2+ singly from aqueous solution. The data
revealed that the isolates kw 9, kw 14, kw 27, kw 28, kw 36, kw 40, kw 42,
kw 49, kw 52, kw 58, kw 66, were recorded the highest biosorption
percentage above 70% for heavy metals ions singly (one at least).
