Sponge bacteria, a chemical factory

Sponges are unique beings: they are invertebrates that live in symbiosis with sometimes hundreds of different types of bacteria; similar to lichens which are a biocoenosis of algae and fungi. "Put simply, many sponges are ...

Modifying one cell factor alters many others

Using a widely studied species of cyanobacterium, researchers from the RIKEN Center for Sustainable Resource Sciences have shown how difficult it is to alter the metabolism of a unicellular organism with the aim of producing ...

Metabolically engineered E. coli producing phenol

Many chemicals we use in everyday life are derived from fossil resources. Due to the increasing concerns on the use of fossil resources, there has been much interest in producing chemicals from renewable resources through ...

Mitochondrial cooperatives

Mitochondria, the organelles that supply the cell with energy, are highly dynamic and can link up to form complex tubular networks. A new study shows that this response can transiently compensate for a shortfall in energy ...

Protein team produces molecular barrels

Research groups headed by Prof. Dr. Nikolaus Pfanner, Dr. Nils Wiedemann, and Dr. Thomas Becker from the University of Freiburg and their colleagues have demonstrated how molecular protein barrels form in the outer membrane ...

Using bacteria batteries to make electricity

(Phys.org) —Their idea is state of the art: Ten Bielefeld students have set their sights on constructing a bio-battery. They want to make use of the bacteria Escherichia coli to convert glucose into energy. With this project, ...

Breakthrough: Sensors monitor cells at work

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. These transported molecules ...
