Corallochytrium limacisporum
 
Description ATP and organic carbon (OC) contents of cells of 5 isolates of thraustochytrids, including one of Corallochytrium limacisporum were estimated from cultures OC:ATP ratio in these isolates averaged 99 Based on these and the data collected on the number of C limacisporum, total viable bacteria (saprophyte numbers), chlorophyll a content and total ATP in the lagoon waters, the contribution of C limacisporum to the microbial biomass in coral reef lagoons of the Lakshadweep islands was calculated The thraustochytrid contributed 2.88 to 213.57% ATP and 1.15 to 85.43% OC relative to total viable bacteria and 0.024 to 3.09% ATP and 0.002 to 1.24% OC to total microbial biomass C limacisporum and total viable bacteria together contributed only 0.844 to 6.02% ATP and 0.822 to 4.97% OC to the biomass About 90% of the microbial biomass in the lagoons appeared to be from organisms other than the thraustochytrid, total viable bacteria and phytoplankton
