Abstract
The population and modernization of society have increased dramatically from past few decades. In order to meet societal expectations, there has been a massive industrialization and resource exploitation. Anthropogenic practices like disposal of hazardous waste, large carbon footprint release variety of xenobiotic substances into the environment, which endanger the health of the natural ecosystem. Therefore, discovering proper long-term treatment approaches is a global concern. Various physical and chemical approaches are employed to remove contaminants. However, these technologies possess limitations like high cost and low efficacy. Consequently, bioremediation is regarded as one of the most promising remedies to these problems. It creates the option of either totally removing pollutants or transforming them into nonhazardous compounds with the use of natural biological agents. Several microorganisms are being utilized for bioremediation among which yeasts possess benefits such as high biodegradability, ease of cultivation etc. The yeast of Candida genus has the capability to effectively eliminate heavy metal ions, as well as to degrade and emulsify hydrocarbons which makes it a promising candidate for this purpose. The review highlights many potential uses of Candida in various remediation strategies and discusses future directions for research in this field.
