Researchers in Germany and Switzerland used next generation sequencing to study an active aquaponics system. They sampled a biofilm from the side of the tank, the fish excrement, the plant roots, and the inside of the tank filter, called a biofilter.
Choosing the right species of algae is one of the most important first steps, they report, as it ultimately impacts the engine’s performance and amount of exhaust emissions.
The latest cutting-edge water filtration technique comes from a biochemistry process that predates even dinosaurs. It involves harnessing aquaporins, a protein in cell membranes which are present in all living things.
Organic farming and conventional farming each have their own strengths and weaknesses that depend on application.
Nitrogen pollution is a big problem in standing water such as lakes and ponds. The nitrogen comes from many sources, often agricultural fertilizers. Some of this nitrogen is in the water, but the rest of it is actually trapped in READ MORE
Plants have five basic needs – food, water, air, light, and space. Outdoors, plants get everything they need from nature and some human intervention. However, when growing plants indoors, these five basic needs have to be provided artificially. Why would READ MORE
A group of agricultural researchers at West Virginia University wanted to find out if it was possible to grow lettuce year round using high tunnel aquaponics instead of traditional greenhouse methods. Aquaponics is a term that combines “aquaculture,” the practice READ MORE
For several decades scientists have been interested in the ability of psychrophilic (cold- loving) microbial communities to degrade the various components of crude oil, which is a process known as bioremediation. Because temperature has a direct impact on enzyme activity READ MORE
Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions. In a READ MORE
Harnessing ‘people power’ to manage fisheries in the developing world has significantly benefited local communities and coral reefs, according to new research. “Studies about the environment, and particularly fisheries, abound with bad news, but here, we see a glimmer of READ MORE
