Schizochytrium mangrovei sp. nov., a thraustochytrid from mangroves in India

Abstract

Schizochytrium mangrovei sp. nov. on decaying mangrove leaves is described from Goa, India. In sea water/pine pollen cultures, the encysted zoospore divides by repeated binary divisions to form 4, 6, 8 or 12 cells. Instead of forming sporangia as in the other species of Schizochytrium, these cells directly become zoospores. In nutrient liquid media, the developmental stages resemble those of Ulkenia. A key to the species of Schizochytrium is given.
