The setups were monitored at two weeks interval over 42-days period at room temperature (approximately 30°C) on a static shake-flask system. The physico-chemical parameters of the samples were analyzed using standard chemical methods such as the atomic absorption spectrophotometry, Gas Chromatography (GC-FID) and the titrimetric technique. The result of primary biodegradation rate revealed that the mixture of Eco-Remover, seawater and crude oil (L2) was the highest degraded at 77.1%, followed by Eco-Remover and seawater combination (L1) at 4.39%. K1 (a mixture of seawater and Rigwash) and K2 (a mixture of crude oil, seawater and Rigwash) degraded at 1.22% and 1.19% respectively. The result also in...
