Abstract
Microbial conversion of petroleum resins existing in a heavy fraction of crude oil was investigated by native isolated consortia. The heavy oil fraction was taken from an end cut of distillation tower of Abadan refinery in Iran. Several Soil samples were taken from different oil contaminated sites of Abadan oil refinery in Khuzestan province. Seven bacterial consortia were then prepared by enrichment method and were examined for their ability to convert resins. Amongst them, consortium AB6 reduced 37.3% of resins while, aliphatic and aromatic compounds increased by 86.8% and 6.7%, respectively. Three pure cultures were isolated from consortium AB6 which were identified as Serratia sp., Raoultella sp. and Ochrobactrum sp.
Highlights
The decision by some governments against Genetically modified (GM) crops might be acrimonious for many but the message is loud and clear–we must win the trust of the consumers and the farmers before bringing any genetically engineered technology or product from laboratory to the fields and to our dinning tables
Transgenic or gene cloning provides a new dimension to crop breeding by enabling direct changes to be made to the genotype of a plant, circumventing the random processes inherent in conventional breeding
In India the attack on the Bt cotton by the mealy bug had reduced the cultivation area under GM crop to half and farmers had no option but to blame the government for encouraging them to go for genetic seeds which led to the poor production
Summary
The decision by some governments against GM crops might be acrimonious for many but the message is loud and clear–we must win the trust of the consumers and the farmers before bringing any genetically engineered technology or product from laboratory to the fields and to our dinning tables.
