Growth assessment of Water Soluble Fractions of Crude Oil and Some of its Hydrocarbons Fractions Using a Diatom (Nitzschia palea)
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2019, Vol 3, Issue 1
Abstract
Growth assessment of water soluble fractions (WSF) of crude oil and some of its hydrocarbon fractions were carried out using a fresh water microalga (Nitzschia palea). The microalga was grown separately in ratios 1:3 and 1:9 of 10%, 25%, 50%, 75% and 100% of water-soluble fractions (WSF) of Forcados blend crude oil and hydrocarbons (Hexane, Benzene, Toluene and Xylene). Algal growth response was evaluated using spectrophotometer at an absorbance of 745nm. Growth stimulation was recorded by the alga at all concentrations of the various WSFs. Also, microalgal growth stimulation in ratio 1:3 crude oil water ratios were higher than that of 1:9 crude oil water ratios why the reverse was the case in WSFs of the hydrocarbons. Among the hydrocarbons investigated, the order of growth stimulation of the alga is Hexane > Xylene > Benzene > Toluene.
