Environmental Biotechnology

Environmental biotechnology is the application of various techniques of biology in order to conserve environment. An environment has always played an essential role in shaping up of an individual whether it is physical or mental health. Thus, it's protection and maintainance is a mandatory duty of every individual. The application of biotechnology in environment has led to the development of environmental biosensors as well as biological waste treatment techniques. It has always tried to provide essential methodologies to improve the quality of an environment.

The application of biotechnology are most prominently in environmental monitoring and waste treatment which are increasing tremendously. Living organisms are manipulated to offer a large range of methodologies that can help in the protection of environment.

Environmental monitoring

It includes the set of methodologies that detects alterations in the parameters of environment which in turn indicates the level of pollutants in the environment. Living organisms have always proved to be an indicator of the harmful levels of pollutants present in the environment. For e.g. the overgrowth of algae have proved to be an indicator of water pollution.
Biotechnology has always focused on developing the strategies for having a record about the ongoing  levels of pollutants in order to aware the scientists to take the necessary precautions.

The concentration of certain compounds from any of the components of environment such as organic pollutants and toxic compounds can be detected by using biosensors. Biosensors are the type of sensors that uses a biological element to detect the concentration of a particular parameter. A biological recognition element can be an antibody, a nucleic acid or a microorganism which can be manipulated by usimg genetic engineering in a biosensor to produce response a against particular pollutant which is amplified and detected.

Waste treatment

Wastes are unusable products generated by living organisms that can degrade or stay in the environment for a period of time.The treatment of waste is one of the most significant method in protecting the deterioration of an environment. Biotechnology includes various methods such as bioremediation, phytoremediation, biofiltration, etc.


Bioremediation is the treatment (remedy) of wastes by microorganisms. The mechanism uses certain metabolic pathways of the microorganisms to breakdown wastes into a more degradable or less harmful product.


Phytoremediation is the use of plants to treat wastes. It involves the taking up of wastes from a plant which gets converted in a particular form and gets stored in the plants.Thus, microorganisms or plants can be genetically modified to breakdown certain types of wastes or they can be used


Biofiltration involves the use of microbes in membrane to breakdown organic matter of the waste. The organic matter supplies food for the microbes in the membrane and necessary aeration is supplied.

Thus, biotechnology plays a vital role in protecting as well as keeping a record on the parameters of a particular environment.

Biotechnology: A Boon or a Bane

The techniques used to utilize living organisms for the benefit of humans forms the basis of biotechnology. One of the most important question that comes to one's mind while they come to know about biotechnology is that whether it is actually beneficial for us or is it just something which has short term benefits with long term ill effects?

The techniques of biotechnology are as old as 6000 years when the ancient people used fermentation to produce food products. The modern biotechnology is quite a new field with having it's roots around 1971 and therefore it is quite essential to know the pros and cons of it.

Biotechnology: A boon The usefulness of microbes has proved to be a boon in pharmaceutical, agricultural and food processing industries.

Biotechnology has not only helped to modify the agricultural crops for increasing their nutritional aspects but has also increased their yields. Thus, biotechnology has proved to be a boon for the farmers. Genetically modified insectic…

6 Reasons to Study Biotechnology

Biotechnology has been a subject of discussion in the past few decades due to its uniqueness as well as its significance. Many people tend to like it as a subject because it has a lot interesting as well as exciting stuffs. The following are the list of reasons why studying biotechnology is cooler than you think it is

1. Research trends From modifying a crop to increase its nutrient value to using a fish as an indicator of pollution. Biotechnology has always been a subject of great interest for a lots of biology lovers as well as general population. As the field of biotechnology is growing, the research trends are just getting cooler. Research trends in biotechnology are just one of the very interesting topics one can discuss for hours.

2. Chemical reactions The chemical reactions used in the assays to analyse biomolecules gives out wonderful colours. The feeling you get when you generate colours by adding the colouring reagents is just amazing. The reactions while studying biotechno…

5 Scopes of Biotechnologists

The advancements in the field of biotechnology has increased it's scope tremendously. The most common question which comes to our mind is that what are the fields in which someone who has done biotechnology can work viz. applications of biotechnology in daily lives.

Here are some of the fields in which biotechnologists can find their way to success.
1. Pharmaceutical industry The biotechnologists have a great knowledge about the maintenance and operation of various API (Active Pharmaceutical Ingredient) plants. The API plant is basically process of growing microbes in order to produce certain antibiotics like penicillin. Thus, they have a great scope in pharmaceutical industries. A biotechnologist also has a lot of knowledge about the downstream processing of a particular API. 2. Agricultural sector Genetically modified (GM) crops are gaining its significance in agricultural sector. The modification of a crop is done in order to improve the nutritional aspect as well as the yield…
