M. Samimi; M. Shahriari Moghadam

Volume 6, Issue 1 , January 2020, , Pages 109-118

https://doi.org/10.22034/GJESM.2020.01.09

Abstract
  phenol and phenolic compounds are among the most recognized environmental pollutants which exist in industrial wastewater and enter the biological cycles due to the solubility in water. Bioremediation is one of the cost-effective and Eco-friendly methods for phenol removal. In this study, the most effective ...  Read More

Sh.F. Abd El-Kader; G.A. El-Chaghaby; G.M. Khalafalla; R.I. Refae; H.M. Elshishtawy

Volume 5, Issue 1 , January 2019, , Pages 61-70

https://doi.org/10.22034/gjesm.2019.01.05

Abstract
  Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for ...  Read More

Abstract
  This study was investigated the efficiency of activated persulfate and ‎in-vessel composting for removal of total petroleum hydrocarbons. ‎Remediation by activated persulfate with ferrous sulfate as pre-treatment was done at batch system. In the chemical oxidation, various variables including ...  Read More

Optimization of phenol biodegradation by efficient bacteria isolated from petrochemical effluents

M. Shahriari Moghadam; N. Safaei; G.H. Ebrahimipour

Volume 2, Issue 3 , September 2016, , Pages 249-256

https://doi.org/10.7508/gjesm.2016.03.004

Abstract
  Phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. In this study three phenol degrading bacteria from Arak Petrochemical Complex effluent were isolated which consume phenol. Molecular analysis was used to identify bacteria ...  Read More
