Title Bacterivory: a novel dual role for thraustochytrids in the sea
 
Creator Raghukumar, S.
 
Description Two thraustochytrids, Thraustochytrium striatum Schneider and Schizochytrium mangrovei Raghukumar, isolated in 1989 in axenic cultures using pine pollen in seawater from mangroves in Goa, India, were observed in continuous-flow chambers. When grown in the presence of bacteria, both species produced amoebae, which moved using pseudopodia and phagocytosed bacterial cells. Several amoebae were produced in 'sporangia', or isolated vegetative cells transformed directly into amoebae. These findings were confirmed with several single-cell isolations of the protists. The demonstration of phagotrophic amoebae in these organisms suggests a dual role for thraustochytrids in nature, namely a fungus-like breakdown of complex organic molecules as well as bacterivory. This phenomenon also places the thraustochytrids in a unique relationship with many other protistan groups
