Organisms which use osmotrophy are osmotrophs. Some mixotrophic microorganisms use osmotrophy to derive energy.
Mixotroph refers to bacterial physiology and the ability to use alternative sources for metabolism and energy and as being capable of growth in either the absence or presence of light, or with either organic or inorganic compounds for nutrition.
