The accumulation of storage reserves is broadly spread in nature, and among the different compounds stored, carbohydrates and lipids are the most common and important. The accumulation of storage compounds in inclusion bodies is a strategy that allows the survival of microorganisms in different environments since most of these compounds act as element and/or energy sources. A variety of storage reserves is known and among lipids, polyhydroxyalkanoates (PHAs), triacylglycerols (TAGs), and wax esters (WEs) are the most important. These carbon-based internal reserves gained importance in the last years due to the possibility of using them as substitutes of materials and fuels usually obtained from mineral oil. For this reason, the knowledge about the microorganisms that store them, the metabolic routes involved on their formation, and the process conditions that allow their efficient production were subject of many scientific works and constitute the main topic of the present chapter.
