Grade 8 student's antibiotics work earns science fair gold

Abstract:This project is about isolation of filamentous bacteria from soil and experimented how they are useful to humans. We isolated 10 bacteria and tested for bacterial killing activity and protease enzyme production. Four isolates were killing test bacteria, the chemical produced from this isolate can be further developed as an antibiotic. Few isolates were also found producing protease enzyme, can be used in detergent industries.

A P.E.I. national science fair winner has found that some micro-organisms in soil can help fight against two common infections.

Shruthi Bandi, a grade 8 student from Queen Charlotte Intermediate, recently won gold in the junior division of the national science fair. Bandi tested a number of bacteria found in soil against Staph infections and Candida infections, and found some to be effective at fighting them.
"Everyone thinks micro-organisms are bad and they cause diseases, but I wanted to prove that micro-organisms are actually really good and they help fight diseases," said Bandi.
"I found that one of my isolates was able to fight against Staphylococcus aureus and two of my other isolates were able to fight against Candida albicans. I want to continue this experiment further because the results are really intriguing. So it would be cool to develop a drug or medicine that could fight against Staphylococcus aureus."
The bacteria Staphylococcus aureus causes what is commonly known as a staph infection. Candida albicans is a yeast infection.
Bandi also took home $4,000 along with her gold medal from the National science fair.
