Each microorganism has its own specific function whether it has to degrade or adsorb hydrocarbons. One important microorganism is the Thraustochytrid that is a fungoid protist and are common in marine and estuarine habitats. Numerous studies existed on the biodegradation and adsorption of Thraustochytrids on various substances but not on Bunker C oil. Thus, this study aimed to determine the adsorption capacity and mean biomass of Thraustochytrids in Bunker C oil using different cell densities measured in grams. All of the three treatments or cell densities (1 x 105 cells ml-1, 1 x 106 cells ml-1 and 1 x 107 cells ml-1) were triplicated and average values were recorded. Oil dispersant was used as a control. It showed that Thraustochytrid with 1 x 107 cells ml-1 showed the highest adsorbed oil (.057 ḡ) among the three cell densities and showed significant difference at p = .01 but comparable to the control (.066 ḡ). In terms of biomass concentration, all cell densities showed no significant difference at p = .01. Thraustochytrid is a promising tool during oil spill because it has the capacity to adsorb oil.
