Cadmium, and its compounds, has been placed on the blacklists of most international pollution conventions by virtue of its toxicity, potential for bioaccumulation and persistence (Taylor, 1983).The ability of many marine molluscs, and in particular gastropods, to accumulate Cd to a high degree in apparently unregulated fashion has led to their frequent use in monitoring programmes. Thus Cd levels in the winkle,Littorina littorea(L.) closely reflect gradients in environmental contamination (Bryanet al. 1983), demonstrating the excellent ‘indicator’ properties of this group.

Heavy Metal Binding

Water pollution with toxic heavy metals is of growing concern because heavy metals could bring about serious problems for not only ecosystems in the water environment but also human health. Some metal removal technologies have been in practical use, but much energy and troublesome treatments for chemical wastes are required to operate these conventional technologies. In this study, heavy metal-binding proteins (HMBPs) were obtained from metal-stimulated activated sludge culture with affinity chromatography using copper ion as a ligand. Two-dimensional electrophoresis revealed that a number of proteins in activated sludge culture were recovered as HMBPs for copper ion. N-termini of five HMBPs were determined, and two of them were found to be newly discovered proteins for which no amino acid sequences in protein databases were retrieved at more than 80% identities. Metal-coordinating amino acids occupied 38% of residues in one of the N-terminal sequences of the newly discovered HMBPs. Since these HMBPs were expected to be stable under conditions of water and wastewater treatments, it would be possible to utilize HMBPs as novel adsorbents for heavy metal removal if mass volume of HMBPs can be obtained with protein cloning techniques.

The Relationship

Metallothioneins (MTs) are cysteine-rich metal-binding proteins. These proteins play a pivotal role in heavy metal homeostasis and have been widely studied by biochemists, toxicologists, nutritional scientists, and molecular biologists. It is well established that MTs are inducible proteins. They are normally synthesized at low basal levels, but exposure to a wide variety of heavy metals and many organic compounds will dramatically increase synthesis of MTs. This paper summarizes MT induction by reviewing the chemicals that induce these proteins, the molecular mechanism involved in this induction, and the relationship between MT induction and biological function.

Biodegradation Process

The metabolic potential of microorganisms plays an important role in the biodegradation of petrochemical waste. The characteristics of the microbial community involved in industrial wastewater treatment have been reviewed in many studies. Within this review, a complete understanding was provided about the characteristics of microorganisms such as bacteria, yeast, micromycetes, and the role of enzymes in the biodegradation process. Data on the structure of the microbial community and the metabolic potential of individual strains are promising for improving the procedure for preliminary wastewater treatment with an increase in the spectrum of strains that can degrade more toxic and resistant xenobiotics. Deciphering the structure of the microbial community is the key to create a rationally and functionally stable purification system.
