Clean water
UNICEF estimates that over 2.2 billion people worldwide do not have access to clean drinking water. Micro-organisms are responsible for a host of waterborne diseases, but simultaneously offer solutions in purifying water and improving sanitation. Biofertilizers offer promising solutions for reduced nutrient runoff and wastewater recycling. As well as applying microbes to combat the problem, applied microbiologists can use their knowledge of health and disease to reduce cases of waterborne disease.

Rainwater tanks are a popular way for Australians to save water, but new research has found they can also harbour potentially harmful bacteria and metals that could pose health concerns.
NewsCyanobacterium found in clean lakes shows little toxic potential
Scientists have assembled the first complete genomes of Gloeotrichia echinulata, comparing DNA of samples from both West Coast and Northeast lakes. They found no evidence of the machinery required to produce the toxins commonly associated with cyanobacteria.

How indigenous microbes could rescue the Niger Delta
Benzene contamination from decades of oil exploitation has turned the Niger Delta’s groundwater into a slow-acting poison for millions of people. Yet the solution may already be living in the contaminated sediment itself, if only the political will exists to deploy it.
