Top 10 Trends in Environmental Biotechnology
Industrialization and increased human activity have led to environmental degradation due to soil, water, and air pollution. Although there are set regulations each industry should follow to conserve the environment, it remains a daunting task. Scientists have realized that if you can’t control the waste being released, maybe you can manage it.
Initially, chemicals were used to treat waste and other pollutants. However, chemicals turned out to be costly and inefficient. With technological advancement and enhancement in knowledge, scientists now develop sustainable waste treatment and pollutant removal strategies. This branch of biotechnology relies on beneficial microorganisms to create a safe, greener environment.
Some of the emerging environmental biotechnology trends in 2021 are:
Without environmental biotechnology, the world would be full of pollutants and industrial waste. These are elements contributing most to global warming and climate change.
Scientists are now using technology to purify pollutants for a quality environment.
In bioremediation, micro-organisms detoxify pollutants either in water, sediments, or soil. To achieve the purification goal, scientists use processes such as bio-restoration, bio-treatment, and bio-reclamation.
Microbial Enhanced Oil Recovery (MEOR)
Technological advancement has allowed scientists to apply different molecular approaches to encourage hydrocarbon utilization in oil wells. This purifies the oil, therefore, reducing processing costs for increased profitability.
Genomic and proteomic isolations allow for profiling through technologies like fingerprinting and sequencing. This enables scientists to better understand each community and species for creative exploitation.
In MEOR, scientists cultivate hydrocarbon-consuming bacteria that remove pollutants from wells underground, therefore, cleaning the soil. This promotes environmental bioremediation.
MEOR also enables investors to identify new oil wells even with the depleting oilfields.
Bio-electrochemical systems like microbial electrolysis cells or microbial fuel cells are the innovation behind fuel production from biodegradable organic matter. The systems use a biofilm catalyst to create electrical energy or hydrogen.
Besides reducing energy consumption during waste treatment, bio-electrochemical systems will generate adequate electrical energy for industrial or domestic use.
Environmental biotechnologists recognize the important role that bio-electrochemical systems in waste remediation. To exploit the capabilities of this technology, these scientists turn to microbial electro-remediation. The aim of using this innovative waste management strategy is to generate sustainable energy through electro-genesis while recovering the resources.
Industrial waste treatment
Industrial waste is the leading cause of environmental pollution, hence blamed for the climate change effects being experienced on earth. However, advancements in environmental biotechnology have given the world a second chance at saving this planet.
Using microorganisms, biotechnologists can technically and economically treat waste. This process relies on controlled biodegradation and detoxification for a quality environment.
To accelerate the degradation process to treat large volumes of waste, companies are now using bio-augmentation. This innovation comes in handy when you have a low volume of microorganisms for successful bioremediation. Bio-augmentation allows the waste treatment system to achieve its goal regardless of the underlying extraneous factors.
After years of industrialization and human ignorance, the soil is accumulated with heavy metals and other pollutants that affect its physical properties and fertility. This negative environmental impact has adversely affected the agricultural sector, hence the need for soil treatment.
Soil remediation has been around for the longest time but is expensive and inefficient. Phytoremediation happens to be the immediate and most effective soil remediation method. In this process, environmental biotechnologists rely on genetically modified organisms to extract heavy metals and other pollutants in the soil.
The different forms of phytoremediation are phytoextraction, phytodegradation, phytotransformation, phytostabilization, and phytovolatilization.
Biofuels for microbial and process engineering
Innovative approaches in environmental biotechnology have paved the way for the sustainable development of biofuels to use in the engineering aspects. Environmental biotechnologists use innovative approaches to convert plants into biofuels.
Microalgae such as hyacinth undergo bio-refining to reduce water pollution that has endangered the lives of biotic animals and plants. This will meet the need for alternative energy sources that promote environmental conservation for a quality, greener planet.
Creative management of chromium phytotoxicity
Chromium is a toxic chemical that will not only affect the growth of flora but also the development of fauna. Because of the danger chromium poses on human life and the environment, environmental biotechnology has created strategies to prevent these phytotoxic effects. The ameliorative approach is the main process of reducing the chromium being released in industrial waste and to the environment.
Amelioration has limited after-use risks as compared to the traditional metal chelation process.
Enhanced Biological Phosphorous Removal (EBPR)
EBPR is a technologically advanced process of treating sewage in small-scale or domestic wastewater. This system needs an activated sludge that is configured to remove phosphate, which is a toxic pollutant.
EBPR is preferable since it’s cost-effective and is highly sustainable since you only need to obtain the phosphorous-accumulating organisms (PAO).
Environmental biotechnology has seen the development of biosensors that improve bio-monitoring of environmental changes along with the treatment processes. Biosensors come with physiochemical detectors that will sense the presence of certain chemicals in wastewater for remediation.
Microarrays can complement the biosensors to determine how toxic or concentrated a certain pollutant is. This is one of the latest technologies in environmental biotechnology, and it aims at improving waste treatment efficiency.
