Abstract
This article presents data on Aspergillus niger effects on the biologically‐mediated remediation of soil
polluted by raw and treated crude oil (Escravos Light blend). Absorbance of different concentrations of
polluted soil samples (5% and 8% w/w) and types (raw and treated), for simulating different onshore crude
oil spill, were obtained from the Aspergillus niger inoculated samples using ultra violet‐visible (UV‐Vis)
spectrophotometry. This measurement was carried out for each sample at selected intervals for the 30‐
day measurements. The bioremediation data, presented in the article, were subjected to
descriptive/analytical statistics of probability density functions and goodness‐of‐fit test‐statistics for
dataset‐detailing and dataset‐comparisons. Information details from these data of biologically‐mediated
remediation of crude oil polluted soil are useful for furthering research on bioremediation kinetics such
as hydrocarbon content analyses, crude oil pollutant removal performance, biodegradation rate
parameter and biostimulant efficiencies by the Aspergillus niger effects on the different concentrations
of polluted soil.
