Microscopic creatures that live on tiny ocean plastics greatly affect the fate and ecological impacts of marine plastic pollution, according to researchers from The University of Western Australia.

PhD candidate Julia Reisser and colleagues have published an article in the international journal PLOS One that contributed many new records of microbes and invertebrates living on sand-sized marine plastics.

Winthrop Professor Chari Pattiaratchi, Ms Reisser’s PhD supervisor, said there were huge numbers of floating plastics at sea and the study was the first to document biological communities on pieces from Australian waters.

The tiny ocean plastics come from the breakdown of discarded plastic items, such as single-use packaging and fishing gear.

More than 1000 images were taken while examining ocean plastics from Australia-wide sample collections using a scanning electron microscope at UWA’s Centre for Microscopy, Characterisation and Analysis.

The good news is that some of the plastic inhabitants may decrease plastic pollution level at the sea surface, where major environmental impacts occur.

Study co-author Dr Jeremy Shaw said large numbers of silica-forming algae weighed down their plastic host, potentially causing tiny pieces to sink to the bottom of the ocean.

The researchers were also able to see colonies of microbes that seem to be “eating plastics”.

“Plastic biodegradation seems to happen at sea. I am excited about this because the ‘plastic-eating’ microbes could provide solutions for better waste disposal practices on land,” Ms Reisser said.

This is extremely interesting research! It is very important for the human race to better understand what is happening in our oceans and other marine environments as it relates to plastics. More and more research is showing how microbes are able to adapt to their environmental conditions to naturally break down compounds back into the building blocks that nature works with.

This research and others like it will help educate the public about the amazing abilities of those tiny unseen microbes. Its not magic its science, and from research like this as well as many others we will begin to develop a better and more detailed understanding of how microbes (who out number the inhabitants of the planet in a single handful of soil) are always working to restore balance in nature.
