ABSTRACT

Biosorption is a physiochemical process that occurs naturally in certain biomass which allows it to passively concentrate and bind contaminants onto its cellular structure. Though using biomass in environmental cleanup has been in practice for a while, scientists and engineers are hoping this phenomenon will provide an economical alternative for removing toxic heavy metals from industrial wastewater and aid in environmental remediation. It wasn’t until the late 1970’s when scientists noticed the sequestering characteristic in dead biomass which resulted in a shift in research from bioaccumulation to biosorption. Pollution interacts naturally with biological systems. It is currently uncontrolled, seeping into any biologic within range of exposure. The most problematic contaminants include heavy metals, pesticides and other organic compounds which can be toxic to wildlife and humans in small concentration. Thus this study was carried out to suggest a control measure for heavy metal pollution through Biosorption by Penicillium.

Keywords: Biosorption, Contaminants, Pollution, Environmental Remediation and Penicillium.
