The amountof ATP produced in anaerobic cellular respiration varies, but is always somewhat less than aerobic cellular respiration. LIPID CATABOLISM Lipids are not a major energy source for most bacteria. However, some bacteria can produce enzymes called lipases that break down fats to glycerol plus fatty acids. These are metabolized separately, but both can eventually be put into the Krebs cycle. Some bacteria can use the same enzymes to break down petroleum products. Beginning with natural ability and increasing it by genetic engineering, these are currently being used to help clean up oil spills....
