Astronauts in space can now convert their own poo to edible food

In an amazing new research, scientists have successfully discovered a method that can convert human wastes into space food. The new study revealed that using microbes, one can make marmite-like food from human waste to feed the astronauts. 


The latest study was carried out by a group of researchers at Pennsylvania State University. The scientists developed a method to break down the human waste consisting of solid as well as liquid wastes so as to produce protein and fat-rich substances.

The study was lead by Christopher House, a Professor of Geo-Sciences and Director of the Penn State Astro-Biology Research Center. He said, “It’s a little strange, but the concept would be a little bit like Marmite or Vegemite, where you’re eating a smear of microbial food, Prof. House stated. 

The latest space food producing technique has excited the scientists. To carry out the research, the scientists prepared an enclosed cylindrical system and put artificial liquid and solid wastes used in waste management tests as well as select species of bacteria. 

Through anaerobic digestion, the bacteria broke down the waste and this produced methane. From this methane, the researchers successfully produce microbe named Methylococcus capsulatus made up of 52 percent protein and 36 percent fats.

According to the researchers, this process of microbial growth offers a potentially feasible way of creating nutritious food for astronauts in space. it can be said that continuous supply of food can be arranged for deep-space missions in future.
