The kidneys are responsible for excreting the majority of potassium from the body. The salt gland is an organ for excreting excess salts. Demineralization is caused by bacteria excreting acids as a product of their metabolism of carbohydrates. The cells lining the tubule modify the fluid inside, absorbing some material and excreting others. The process involves bacteria feeding on hydrocarbons and excreting hydrogen and CO. The species can tolerate high salinity by excreting salts through its leaves. Damage can occur from pests consuming, burrowing into, and excreting on material. Some bacteria can change the pH such as by excreting acid resulting in sub-optimal conditions. However, the structures for excreting salt to maintain osmoregulation are typically more complex. A suitable method for excreting it must therefore exist.
