Biofilms can grow in the most extreme environments: from, for example, the extremely hot, briny waters of hot springs ranging from very acidic to very alkaline, to frozen glaciers. Biofilms can be found on rocks and pebbles at the bottoms of most streams or rivers and often form on the surfaces of stagnant pools of water.
Surface roughness can also affect biofilm adhesion. Rough, high-energy surfaces are more conducive to biofilm formation and maturation, while smooth surfaces are less susceptible to biofilm adhesion. The roughness of a surface can affect the hydrophobicity or hydrophilicity of the contacting substance, which in turn affects its ability to adhere.
A colony of limpets attached to a diving mask, found washed ashore on a beach The plastisphere is a human-made ecosystem consisting of organisms able to live on plastic waste. Plastic marine debris , most notably microplastics , accumulates in aquatic environments and serves as a habitat for various types of microorganisms, including bacteria ...
In total, the researchers found 16 plastic fibers and particles in the tissues. The smallest were slimmer than the diameter of a human red blood cell, which measures about 8 micrometers. The most ...
Phototrophic biofilms can be found on terrestrial and aquatic surfaces and can withstand environmental fluctuations and extreme environments. In aquatic systems, biofilms are prevalent on surfaces of rocks and plants, and in terrestrial environments they can be located in the soil, on rocks, and on buildings. [1]
The analysis, published in the Journal of Exposure Science and Environmental Epidemiology on Monday, reveals that 3,601 food contact chemicals, or FCCs, were found in human samples of urine, blood ...
EPS is found in the matrix of other microbial biofilms such as microalgal biofilms. The formation of biofilm and structure of EPS share a lot of similarities with bacterial ones. The formation of biofilm starts with reversible absorption of floating cells to the surface. Followed by production of EPS, the adsorption will get irreversible.
Biofilms can consist of a multitude of bacteria, fungi, and algae which are able to absorb, immobilize, and degrade many common pollutants found in wastewater. By harnessing a natural phenomenon, biofilm-mediated remediation is an environmentally friendly method for environmental cleanup. [3]
