Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. view more (2007-07-30)
Recycling water in buildings by microbes
New information about how households and businesses can recycle and re-use their own water suggests that a submerged membrane bio-reactor could be the best method. The aim is to make water a more sustainable resource by reducing the amount that needs to be treated by large, central facilities. The work is being carried out in Cranfield... view more...

Better sludge through metagenomics
Few stop to consider the consequences of their daily ablutions, the washing of clothes, the watering of lawns, and the flush of a toilet. However, wastewater treatment-one of the cornerstones of modern civilization-is the largest microbially-mediated biotechnology process on the planet. view more (2006-09-26)
Mopping up mercury - a new solution to an old problem
A pilot plant employing a new type of bioreactor has successfully been used to treat mercury-contaminated wastewater in Germany. Dr Irene Wagner-Döbler and colleagues from the GBF National Research Centre for Biotechnology, Germany, developed the technical scale plant based on previous work on mercury-resistant bacteria. Biofilms of bacteria... view more... (2001-04-01)
U of M researchers discover key for converting waste to electricity
Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms. view more (2008-03-04)
Scientists equip bacteria with custom chemo-navigational system
Using an innovative method to control the movement of Escherichia coli in a chemical environment, Emory University scientists have opened the door to powerful new opportunities in drug delivery, environmental cleanup and synthetic biology. view more (2007-05-11)
Manufactured Buckyballs don't harm microbes that clean the environment
Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to Purdue University researchers. view more (2008-04-09)
Studying the fate of drugs in wastewater
Researchers at the National Institute of Standards and Technology (NIST) have published an interesting study that sheds light on the fate of a familiar pharmaceutical as it enters the waste stream. view more (2005-12-27)
Nitrous oxide: definitely no laughing matter
Farmers, food suppliers, policy-makers, business leaders and environmentalists are joining forces to confront the threat of the 'forgotten greenhouse gas' by taking part in an influential new forum at the University of East Anglia (UEA). view more (2008-02-19)
Chronicle of Martian Expedition
A man is the most vulnerable chain in long-term space expedition. How numerous should a crew be? What are the principles of a crew selection? What should be made to protect people during a flight and on some other planet? Scientists from the Institute for Problems of Medicine and Biology are trying to answer these and many other questions. With... view more... (2001-04-20)
Are drugs harmful for the environment?
Medicines released into the environment may be a risk to living species in the long term. Jeanne Garric's ecotoxicology team at Cemagref Lyon has shown that certain molecules disrupt reproduction, embryo development and growth of representative organisms in aquatic environments. Toxicity tests have been conducted in the laboratory on Daphnia,... view more... (2003-06-11)
Microbes Churn Out Hydrogen at Record Rate
By adding a few modifications to their successful wastewater fuel cell, researchers have coaxed common bacteria to produce hydrogen in a new, efficient way. view more (2007-11-14)
Pointing a finger at the source of fecal bacteria
Excessive levels of fecal bacteria were to blame for almost 60 percent of Nebraska streams deemed impaired by federal and state environmental laws in 2004. view more (2007-05-24)
Using plants and microbes to purify polluted industrial wastewater
Wetlands are nature's water filters. They collect water around river mouths and marshes, and whole communities of plants and micro-organisms feed off detritus in these murky depths. Conventional chemical treatments of industrial waters consume cash, energy and time. Wetlands, by contrast, grow and clean themselves while they act as... view more... (2003-10-07)
Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes... view more...

Sewage tells tales about community-wide drug abuse
Public health officials may soon be able to flush out more accurate estimates on illegal drug use in communities across the country thanks to screening test described here today at the 234th national meeting of the American Chemical Society, the world's largest scientific society. view more (2007-08-22)
Commercial aquatic plants offer cost-effective method for treating wastewater
Nursery and greenhouse operations depend on the use of fertilizers, growth regulators, insecticides, and fungicides. Growers also rely on the use of soilless media, or substrate, in the production of container crops. view more (2008-09-30)
Nominations sought for 2001 Stockholm industry water award
Award Honors Business Contributions to Sustainable Water Development Companies that have contributed to pollution elimination or reduced freshwater consumption through innovative programs, policies, processes or products now have the opportunity to nominate themselves for the prestigious Stockholm Industry Water Award. Until February 28, 2001,... view more... (2000-11-02)
Store-bought freshwater fish contain elevated levels of mercury, arsenic and selenium
White bass wild-caught and sold commercially contained significantly higher levels of mercury, arsenic and selenium than fish caught near former industrial areas. view more (2007-11-07)
