available organic molecules are formed known as volatile fatty acids (VFAs). VFAs typically found in wastewater are acetic acid (acetate) and propionic acid. VFAs provide the food for PAOs. Polyhydroxyalkanoates (PHAs) are energy-rich carbon polymers inside a bacterial cell,
Polar Amino Acids The side chains (R groups) of the amino acids can be divided into two major classes, those with polar side chains (shown here) and those with nonpolar side chains. The polar amino acids include: arginine, asparagine, aspartic acid (or aspartate), glutamine, glutamic acid (or glutamate), histidine, lysine, serine, and threonine. Polar side chains contain groups that are either charged at physiological pH or groups that are able to participate in hydrogen bonding.
