Biodegradation of Phenolic Components in Wastewater by Micro Algae: A Review

The biodegradation of phenolic contaminant present in wastewater by micro algae has been investigated in the current research. The study focused on algae growth requirements and factors affecting algae growth in contaminated water leading to the best treatment. Different techniques used to functionalize microalgae in the treatment such as batch and continuous operation modes have been further investigated. Mechanisms for microalgae pollutants degradation and microalgae growth kinetics were also highlighted to present the required knowledge in phenol contaminant biodegradation field by microorganisms

Bioremoval Capacity of Phenol by Microalgae

Bio-treatment of phenol contaminated wastewater by 3 types of algae (Anabaena fetilissima Sps., Chroococuss minor Sps., Westiellopsis prolifica Sps.) had been investigated by current study. This work was conducted using synthetic wastewater with different concentrations of phenol (0.5, 2 and 5 mg/L). The comparison between algae capacity for removal was established according to the cell concentration, initial phenol concentration and pH, this study was extended to include testing algae in treating high phenol concentration. Complete removal of phenol as a single aqueous solution in different concentrations (0.5, 2, 5 mg/L) was observed by Anabaena fetilissima species under optimum treatment conditions. Furthermore, Anabaena algae was able to remove high phenol concentration upto 100 mg/L with the minimal doubling time, high specific degradation and growth rate. These results nominated Anabaena algae to be the most sufficient and useful algae in treating phenolic among the studied algae species examined. The results indicated that the potential of natural resources as effective agent for pollution control
