Bio
Bang’s specialty is Bioremediation, that is, simply stated, using biology to fix things that are broken in the environment. Specifically, for some years now Bang has been working with graduate student advisees to perfect a process of “selective microbial plugging.”
Many types of bacteria are efficient at extracting the nitrogen they require to live from urea (the nitrogenous component of urine, produced by many microorganisms). The process produces carbon dioxide and ammonia as byproducts. If water is also present, that ammonia will react with it to form ammonium hydroxide; if calcium is also present, that ammonium hydroxide will react with it to form crystals of calcium carbonate. Calcium carbonate (CaCO3) is better known as limestone.
What Bang and her research teams have done in the lab is to speed up this chain reaction, which occurs in nature very slowly. They mix two common types of soil bacteria, Bacillus pasteurii and Sporosarcina ureae, with sand and “feed” the bacteria a rich solution containing both urea and calcium chloride. After using up the supply of nutrients, the bacteria die, but by that time, the calcium carbonate has crystalized the sand into solid limestone.
