Over the past 2 decades more and more emphasis has been placed on reducing carbon dioxide in the atmosphere and how to reduce green house gasses. But how can oxygen levels be increased. Scientists in the Netherlands have found a bacteria that is able to do just that.

Microbiologists have discovered
Oxygen producing bacteria
bacteria that can produce oxygen by breaking down nitrite compounds,a novel metabolic trick that allows the bacteria to consume methane found in oxygen-poor sediments.
Previously,researchers knew of three other biological pathways that could produce oxygen. In photosynthesis,microbes or plants containing chlorophyll grow by gleaning energy from the sun,releasing oxygen as a waste product. In the two other schemes,cells generate oxygen — typically for their own internal use — by using enzymes to break down oxygen-containing substances such as chlorates,says Katharina Ettwig,a microbiologist at Radboud University Nijmegen in the Netherlands.
Ettwig’s team studied bacteria cultured from oxygen-poor sediment taken from canals and drainage ditches near agricultural areas in the Netherlands. The scientists found that in some cases the lab-grown organisms could consume methane — a process that requires oxygen or some other substance that can chemically accept electrons — despite the dearth of free oxygen in their environment. The team has dubbed the bacteria species Methylomirabilis oxyfera,which translates as “strange oxygen-producing methane consumer.”
Along this water,oxygen is essential to life on earth. Scientific studies are showing that plants are already absorbing and converting carbon dioxide (CO2) into Oxygen at the fastest rate possible. Could you imaging what would happen if the oxygen percentage dropped to the point where human intervention would be required to purify the air we breath?
The world is already at a point where human intervention is needed for safe,clean water consumption. Is enough being done to ensure high quality drinking water standard for the years to come? Will we be forced to buy expensive bottled drinking water in the future?
