В ноябре спортсмен отказался от пояса по версии WBO и, таким образом, он перестал быть абсолютным чемпионом мира. На профессиональном ринге Усик провел 24 матча, в которых не потерпел ни одного поражения и одержал 15 побед нокаутом.

This was not the first time that microbiologists experienced problems with agar. A phenomenon called “The Great Plate Count Anomaly” baffled researchers in the early 20th century when they observed that the number of cells seen under a microscope didn’t match the actual number of colonies growing on an agar plate. Investigating this discrepancy, researchers found agar itself to be the culprit: when nutrient broths are heated with agar during boiling, harmful byproducts (hydroperoxide) can form due to the reaction of agar with phosphate minerals contained in the media. Researchers can avoid this by autoclaving agar separately from the nutrient broth, or by reducing the amount of agar used.
Other campaign groups, like the Wildlife Trusts, insist that many more fish are at risk. They highlight research from Natural England that found that over seven million fish would die if no measures whatsoever were put in place.
