Bioremediation

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.

In this study the earthworm Eisenia andrei and sunflower dwarf sensation (Helianthus annuus) were used as tools to accumulate Pb and stable Cs. The aim of this study was to evaluate bioremediating Cs and Pb in contaminated soils using the selected biota. The efficacy of this bioremediation was evaluated using integrated soil microcosms (ISM)–a multispecies mini ecosystem with soil contaminated with Cs alone at 25 mg/kg and 250 mg/kg; Pb alone (1500 mg/kg) and Pb (1500 mg/kg) together with Cs (250 mg/kg) in the laboratory.

In this work, we review various PhCs detected in water treatment plants. We propose that fungi, particularly white-rot fungi (WRF), can be used for their bioremediation and describe the main mechanisms used for degrading this type of emerging pollutants; however, we also highlight the need to prospect for new fungal models.

In the present investigation, bacterial species such as E. coli, S. aureus and S. bongori were isolated from soil by using serial dilution. Bioremediation results showed the S. aureus was highly efficient on Diazinon removal by 62%, 63.2% and 68.6%, Pirimicarb removal was 44%, 52.4% and 53.8%, and Atrazine removal was 61%, 65.6% and 70.6%. and the efficiency of E. coli removal on Diazinon was 59%, 60.8% and 63.8%; on Pirimicarb was 44%, 52.4% and 53.8%; and for Atrazine 57%, 60.8% and 64.4%. S. bongori efficiency on Diazinon was 49%, 51.2% and 55.8%; on Pirimicarb removal was 61%, 63.

Bioremediation presents a potentially low cost and environmentally agreeable alternative to current physico-chemical remediation strategies. However, heavy metals such as mercury cannot be converted into non-toxic forms by naturally occurring bacteria. Annual global emissions estimates for mercury released into the environment are in the thousands of tons per year [1,2] while the remediation cost is in the thousands of dollars per pound. Finding new bioremediation technologies is an urgent need.

Bioremediation strategies use microorganisms to remove hazardous sub-stances, such as aromatic molecules, from polluted sites. The applicability of these techniques would greatly benefit from the expansion of the cata-bolic ability of these bacteria in transforming a variety of aromatic com-pounds.
