Bacteria were discovered in rumen fluids, which is the biggest compartment of a ruminant s stomach. Ruminants rely on microorganisms to help break down their coarse plant diet. The researchers hypothesized that some microorganisms in a cow s rumen would be able to digest polyesters.

Cows eat cutin, a natural polyester generated by plants, as a result of their herbivorous diets. Being a synthetic polyester, PET has a chemical structure comparable to that of this natural material. According to corresponding author Doris Ribitsch, a senior scientist at the University of Natural Resources and Life Sciences in Vienna, cutin makes up most of the cuticle or waxy outer layer of plant cell walls. Thus, it can be found in abundance in the peels of tomatoes and apples, for example.
Cows Have Hungry Stomach Microbes Capable of Breaking Down Some Plastics

Microbes fished from the stomachs of cows can gobble up certain kinds of plastic, including the polyethylene terephthalate (PET) used in soda bottles, food packaging, and synthetic fabrics.
Scientists uncovered these microbes in liquid that was drawn from the rumen, the largest compartment of a ruminant s stomach; ruminants include hooved animals like cattle and sheep, which rely on microorganisms to help break down their diet of coarse vegetation.
The rumen acts as an incubator for these microbes, which either digest or ferment foods consumed by a cow or other ruminant, according to the University of Minnesota.

Manitoba has dropped further down the rankings of the Fraser Institute’s annual ranking of mining companies.
Manitoba has dropped further down the rankings of the Fraser Institute’s annual ranking of mining companies.
After reaching lofty heights of No. 2 in 2016 in the investment attractiveness index out of 104 international jurisdictions the Fraser Institute ranks Canadian provinces, and Australian and U.S. states individually this year Manitoba is a humbling 37th.
It has been falling steadily for the past few years, ranking 34th last year after first reaching the top 10 in 2014.
While the whole industry has been suffering from depressed commodity prices, the fact is that Manitoba was only ranked higher than Nova Scotia, Nunavut and Northwest Territories among Canadian jurisdictions this year.
