Russian scientists recently isolated a gluconooxygenous bacillus from soil contaminated by petrochemicals, which can decompose 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) that has an adverse effect on the environment. Herbicides are expected to be used to clean up related contaminated environments. The 2,4,5-T herbicide was a compound that was synthesized half a century ago. It was used as a herbicide at that time and was included in the "orange agent" used on the Vietnam battlefield. Later, the expert discovered that because the compound contained three chlorine atoms, ordinary bacteria could not be decomposed. After the herbicide is used, it will remain in the soil for a long period of time, leading to gene mutations in biological cells and reducing the reproductive capacity of the organism. According to the Russian "Science Information" magazine, experts from the Ufa Science Center of the Russian Academy of Sciences recently discovered an oxidized Gluconobacter oxydans, called IRBB-2T, which is expected to solve the problem of environmental pollution caused by this herbicide. The bacteria were isolated from soil contaminated by petrochemicals containing phenols and chlorophenolates. It has been found that the bacteria can grow in environments containing 2,4,5-T herbicides from 22 degrees Celsius to 41 degrees Celsius, and decompose the chlorine atoms in the 2,4,5-T herbicide compounds. The agent serves as the sole source of energy. Further studies have found that in the environment containing 0.1 g of 2,4,5-T herbicide per kilogram of soil, the bacteria can break down two-thirds of the herbicide in the soil within 48 days. In the liquid environment, bacteria will be more able to break down. In a solution containing 0.1 g of 2,4,5-T herbicide per litre, the bacteria can break down 40% of the herbicide in 5 days and 88% of the herbicide in one week. Russian researchers said that after the bacteria break down the chlorine atoms in the herbicide, the herbicide can be further decomposed by common bacteria. The research results of this herbicide resistance herbicide have been patented in Russia.
