Copper biosorption by Bacillus pumilus OQ931870 and Bacillus subtilis OQ931871 isolated from Wadi Nakheil, Red Sea, Egypt.

ABSTRACT:

Background

Despite being necessary, copper is a toxic heavy metal that, at high concentrations, harms the life system. The parameters that affect the bioreduction and biosorption of copper are highly copper-resistant bacteria.

Results

In this work, the ability of the bacterial biomass, isolated from black shale, Wadi Nakheil, Red Sea, Egypt, for Cu²⁺ attachment, was investigated. Two Cu²⁺ resistance Bacillus species were isolated; Bacillus pumilus OQ931870 and Bacillus subtilis OQ931871. The most tolerant bacterial isolate to Cu²⁺ was B. pumilus. Different factors on Cu²⁺ biosorption were analyzed to estimate the maximum conditions for Cu biosorption. The q_max for Cu²⁺ by B. pumilus and B. subtilis determined
