Exceeding the secondary voltage may also degrade the accuracy of the transformer or destroy it. Interference can degrade the signal or cause the system to fail. The heat also inactivates enzymes which could otherwise degrade NAD. This process can simultaneously degrade organic carbon waste and generate electricity. Using more than one codec or encoding scheme successively can also degrade quality significantly. Microbes degrade many fertilizers, e.g., by immobilization or oxidation. However, certain organisms are able to degrade it, albeit very slowly. However, the efficiency of air conditioners can degrade significantly over time. Certain white rot fungal strains can also degrade Nylon 6 through oxidation. This helps eliminate radio frequency radiation, which would degrade SQUID performance. A number of microorganisms can degrade polyvinyl acetate. They do not degrade at high temperatures either. However, CAB can degrade with exposure to heat and moisture, releasing butyric acid. Excessive heat can also degrade, or break down, the gelatin itself. It produces AHLs and also, it can degrade the AHL molecules as well.
