Comamonas testosteroni is a Gram-negative environmental bacterium capable of utilizing testosterone as a carbon source, and degrading other sterols such as ergosterol and estrogens.[1] Strain I2gfp has been used in bioaugmentation trials, in attempts to treat the industrial byproduct 3-chloroaniline.[2] It was first classified as a human pathogen in 1987 according to the National Library of Medicine. After years of testing, it has been revealed that it can digest certain types of plastic.[3]

Benefits

Plastic is not organic and can take years to decompose. It is bad for our environment as it increases global warming and pollution. Scholars have gone as far as to call it “nature’s plastic recycling center".[4] There is also optimism that scientists can study how comamonas testosteroni digests plastic and replicate it artificially and more efficiently

Virulence

Though these organisms have low virulence, they can occasionally cause human diseases. They can be found in intravenous catheters, the respiratory tract, abdomen, urinary tract, and the central nervous system. Symptoms of infection may variously include vomiting, watery diarrhea, and meningitis.[5]
