Importance of bioremediation and its future prospects

Bioremediation helps cleaning up polluted environments, including soils, groundwater and marine environments. Such systems can include bacteria, fungi, algae and plant species. They are capable of metabolizing, immobilizing or absorbing toxic compounds from their environment. However, a major advantage of these systems is that they are less harmful to the environment with minimum or no by-products. Read more »

Harvesting useful byproducts from bioremediation

With the ever-increasing population of the world, the utilization and therefore the demand for energy resources is also increasing. Also, the quick diminishing rate of the natural resources due to their degradation has created an urgent need to find alternative resources (Sasikumar & Papinazath, 2003). In the long run, bioremediation can help fulfill the increasing demands for energy resources, pollution control  and waste management. Read more »

Role of phytoremediation in treating heavy metal pollution

In the previous article, the role of genetic engineering in improving bioremediation were discussed. With rapid industrialization, heavy metal contamination and organic pollutants have increasingly affected soil and water bodies. These threaten the ecosystem, surface and ground waters, food and human health. Phytoremediation is a method which involves growing plants in a contaminated matrix to remove environmental contaminants. Read more »

Gene ontology and gene interaction studies of Arabidopsis Thaliana

The previous article discussed the role of gene ontology in bioremediation. It also studied its importance in identifying new genes or proteins involved in bioremediation. Gene ontology can help in annotating and identifying important genes and proteins of organisms capable of bioremediation. Gene ontology analysis can assist in phytoremediation studies to mitigate dangerous pollutants. Read more »

Role of gene ontology in bioinformatics and bioremediation studies

In the previous articles, gene and protein of interest were studied with respect to their closely related variants found in NCBI database. In this article, gene and their products are studied on the basis of a standardised approach of annotating the correct information. This is based on gene annotation and gene ontology. Gene ontology refers to a consistent method of describing genes and gene products across all species and databases. Read more »

Comparative study of merA genes in arabidopsis for phytoremediation

Mercury is a highly potent neurotoxin impacting the function and development of the central nervous system in people and wildlife. Exposure to it in the form of vapours or organic methylmercury leads to neurological and behavioural issues. Moreover, mercury exposure is toxic to the digestive system, organs and the immune system (World Health Organization, 2017). Mercury pollutants in the environment are present in elemental, inorganic and organic forms. Global heavy metal contamination are increasing in soil due to industrialisation. Read more »

Genetic engineering of plants can contribute to bioremediation efforts

In the previous section, microbial remediation was studied. Bioremediation is a waste management technique to neutralize pollutants from a contaminated site. This is done with the use of organisms which can be microorganisms, fungi, plants or algae. They either metabolize pollutants to less toxic forms, assimilate or immobilize. Bioremediation works in two ways. First is enhanced growth of suitable organisms at the site. Other way is by introducing specialized microbes at the contaminated site to degrade contaminants.

Scope of microbial remediation processes in Phytoremediation to combat pollution

Discussion about environmental pollution and its consequences has become a common place in the wake of frequent environmental disasters like oil spills and radiation leakage. However environmental disasters are not only caused by sudden catastrophes, but also over a long term discharge from anthropogenic activities. These include, continuous discharge of agriculture, mining and industrial effluents as direct consequence of population explosion and industrialization. As of 2016, approximately 5.73 million tons of crude oil has been accidently released into the environment during 1830 incidents in 5 decades, while 2016 alone experienced 6000 tons of crude oil spill (ITOPF, 2017).
