Physicists at the Australian National University have found a way to manipulate the growth of bacterial life (one of the most common forms of life on Earth) in a recent study.
According to News i and quoted by FayzThis success can help scientists improve their knowledge of how to deal with chronic infections and antibiotic resistance, as well as the food we eat and the clothes we wear. Dr. Hua Xia says scientists have been trying to identify and control biomass for decades.
“Bio-layers are created by bacteria to create a safe environment and act as a kind of shield,” said Dr. Xia. Dental plaque, for example, is an example of a biologic layer. Another example outside of our body is a mass of algae that forms a green layer on the surface of stagnant water. They grow on wet surfaces, but they are not necessarily harmful to humans. In wastewater treatment plants and agricultural technology, we use the ability of bacteria to create bio-layers.
In this study, researchers have developed a new approach to controlling biomass formation. Social biofilm is a microorganism cell that attaches to a surface and is covered by extracellular polymeric materials.
Dr. Xia added: “Biomass formation begins when bacteria attach to the right surface. During this study, we were able to control the growth of biomaterials by controlling surface waves.
In addition, we have found that “turbulent motion” causes bacteria not to bind and biostructure to form, but this method of controlling how bacteria behave can lead to new technology for biomaterial formation.
Biomaterial is a substance of artificial or natural origin that is used to improve, treat, heal, or replace tissue in living organisms.
“Wave action works very well in the connection of fluid and air, and when some microorganisms form compounds called bacterial cellulose,” Dr. Xia concluded. This wave-based approach could lead to the engineering of new forms of bacterial cellulose, which is used in all cases, including fabric, cosmetics and food products, as well as medicine. We are now focused on creating different forms of cellulose and controlling its properties, such as water retention capacity or mechanical strength.
The study's findings are published in the journal Science Advances.
