Dhaka the 9th of Feb.,’14. According to a piece of news published in the last February issue of “Current Science”, Bangalore, India, three out of the sixty marine bacteria species, namely, Kocuria palustris, Bacillus pumilus andBacillus subtilis demonstrated their ability to help degrade polyethylene. The efficiency of the bacteria to degrade polyethylene was also determined by measuring growth and metabolic activity on the polyethylene surface.The evidence confirming the biodegradation of polyethylene comes from the presence of dehydrogenases, a group of intracellular enzymes involved in metabolic activities of the bacteria on the polyethylene film in addition to the formation of ester, keto, vinyl and internal double bonds from catalytic enzyme reactions.
In another piece of news published in the same issue ofCurrent Science, the mutant genes in the genetic make-up of the malaria parasite, Plasmodium falciparum causing resistance to the drug artemisinin have been identified. These two reports will enable the concerned companies to market these products after their commercialization.
