Bioluminescence: Application in Biotechnology

by | Dec 21, 2023 | Uncategorized | 0 comments

Bioluminescence has been fascinating to humanity for as long as we can remember, and it has certainly inspired many scientists and non-scientists alike over the last decades.

Bioluminescence is the emission of light by living organisms. This natural phenomenon has been explored mainly in the young field of synthetic biology, and it is a natural phenomenon found in many organisms, including bacteria, fungi, insects, and fish. In the 2021 article Applications of Bioluminescence in Biotechnology and Beyond by Aisha J. Syed and James C. Anderson, they share an overview of the basic mechanism of bioluminescence, in which an enzyme called luciferase catalyzes the oxidation of a substrate molecule called luciferin, and this results in the production of light.

In Bioluminescence: Fundamentals and Applications in Biotechnology (Volume 2), scientists Benjamin Reeve, Theo Sanderson, Tom Ellis and Paul Freemont explain that ‘the natural bioluminescent world includes such varied creatures as beetles, fungi, plankton, and bacteria. To the synthetic biologist, this is an archive from which enzymes with desired properties can be selected.’

Bioluminescence has had many uses, but among the most prominent ones are biomedical research, environmental monitoring, biotechnology, the food industry and forensic science.

First, in medical research, bioluminescence is used as a tool for visualizing biological processes in living organisms as well as medical diagnostics. It helps researchers monitor the activity of specific genes or track the spread of diseases. Bioluminescent imaging techniques can be used to detect cancerous tumors and monitor their growth in real-time.

Within environmental monitoring, bioluminescent bacteria are used to detect toxins in environmental samples. The bacteria produce light in response to the presence of specific molecules, such as pollutants, allowing researchers to detect and quantify them.

With biotechnology, bioluminescence has been used to create biosensors for detecting specific molecules in biological samples. These biosensors are highly sensitive and specific, allowing for rapid and accurate detection of target molecules.

In the food industry, bioluminescence has been used to detect bacterial contamination in food products. The bioluminescent bacteria are engineered to produce light in response to the presence of specific pathogens, allowing for rapid detection and prevention of foodborne illnesses.

And last but not least, in forensic science, bioluminescence has been used to detect trace amounts of blood and other biological fluids at crime scenes. The bioluminescent reaction is highly sensitive and can detect infinitesimal amounts of biological material.

There are a lot more uses to this phenomenon, but one of my personal favorites is its promising use in botany. Bioluminescent trees are a new and exciting field of research that involves engineering trees to produce their own light through bioluminescence. The goal of this scientific experiment is for this research to create sustainable sources of lighting that are environmentally friendly and do not require electricity.

The bioluminescence in trees is created through the same mechanism as in other bioluminescent organisms. The trees are genetically modified to produce a luciferase enzyme, which catalyzes the oxidation of a luciferin molecule, producing light. The light produced by the trees is not bright enough to illuminate an entire room, but it could provide a soft, ambient glow that could be used for outdoor lighting or decorative purposes.

One of the primary motivations for developing bioluminescent trees is to create sustainable sources of lighting that do not contribute to climate change. Traditional sources of lighting, such as incandescent bulbs or fluorescent lights, require large amounts of energy and produce greenhouse gases when they are manufactured and used. Bioluminescent trees, on the other hand, do not require any external energy source and are carbon-neutral. 

Another potential application of bioluminescent trees is in the field of urban forestry. Trees are important components of urban ecosystems, providing numerous benefits, such as improving air quality, reducing heat island effects, and supporting biodiversity. By engineering trees to produce their own light, it may be possible to enhance the aesthetic appeal of urban forests while also providing additional benefits such as increased safety and visibility at night.

However, it is important to note that the development of bioluminescent trees is still in its early stages, and there are many technical and regulatory hurdles that need to be overcome before they can become a practical reality. Nonetheless, the potential benefits of bioluminescent trees make them an exciting area of research with promising applications for the future.


Overall, bioluminescence ‌has proven to be a valuable tool in biotechnology and has led to numerous advancements in various fields. As 2020 Review article Seeing (and Using) the Light: Recent Developments in Bioluminescence Technology states in the journal Cell Press, “Despite the versatility and ubiquity of bioluminescence in biomedical imaging, limitations remain.” But that doesn’t mean scientists and researchers will get discouraged. Quite the opposite, they are very much determined to push the boundaries of what is possible with bioluminescent technologies.
