"Space regulations don't cover the new problems emerging - interference with astronomical observations, risk of collision in orbit, risk of stuff falling on our heads, and now it is becoming clear, atmospheric pollution," says Andy Lawrence, Professor of Astronomy at the University of Edinburgh.
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.，这一点在同城约会中也有详细论述
