Article Synopsis
  • A new method using wheat straw was developed to improve the leaching of salt from soil contaminated with petroleum, blocking the upward movement of the salt.
  • The study found that adding 5% wheat straw significantly enhanced salt leaching efficiency from 3% to 25%, particularly when petroleum contamination was below 1.5%.
  • Field tests revealed that after 50 days, 80% of the area reached normal soil conductivity levels, with a notable reduction in sodium and chloride concentrations, ultimately leading to a 72% wheat production rate compared to the control plot's 12%.

A new bioaugmentation method for petroleum- and salt-contaminated soil was presented, in which wheat straw was used to enhance salt leaching and subsequent petroleum degradation by a bacteria-fungi consortium of Enterobacter cloacae and Cunninghamella echinulata. The effectiveness of a coarse wheat straw layer in inhibiting capillary-induced upward salt movement and in enhancing growth of E. cloacae and C.

Pilot demonstration of the fungal-bacterial augmented in situ remediation of petroleum contaminated soil was carried out in Zhongyuan Oilfield, Henan, using artificially prepared soil, newly and aged contaminated soil as sample, respectively. For the first run of the experiment started from Nov. 5, 2004 and lasted for 122 days, the removal of contaminate was 61.
