Microbial electrolysis cell with a microbial biocathode
Bioelectrochemistry, 2010This study demonstrates, for the first time, the proof-of-principle of an MEC in which both the anodic and cathodic reaction are catalyzed by microorganisms. No expensive chemical catalysts, such as platinum, are needed. Two of these MECs were simultaneously operated and reached a maximum of 1.4 A/m(2) at an applied cell voltage of 0.5 V.

Microorganisms comprise about half of the biomass on our planet and play a key role in the biogeochemical cycling of elements like carbon, nitrogen, and sulfur. Furthermore, due to their small size and short generation time, microorganisms provide ideal model systems for the study of many universal ecological processes.To understand the population ...

Macromolecular Bioscience, 2004
AbstractSummary: This feature article describes the current knowledge on biosynthesis of polythioesters (PTEs), which are exclusively accumulated by microorganisms capable to synthesize the well‐known polyhydroxyalkanoates (PHAs). Two bacterial PTE biosynthesis systems are discussed, both are depending on the cultivation conditions and appropriate ...

Annual Review of Microbiology, 2017
Expansins are small proteins that loosen plant cell walls and cellulosic materials without lytic activity. First discovered in plants, expansin genes are found in the genomes of numerous bacteria and fungi that interact with plants in pathogenic and mutualistic patterns, as well as in microbes that feed on plant debris.

Biomarkers, defined in ecotoxicology as functional measures of exposure to chemicals, may not be informative on the consequences of exposure at the scale of interest, which is the entire ecosystem. This drawback is because links and interactions existing between these measures and the biological system at a larger scale are not always sufficiently ...

Levans are natural polymers of the sugar fructose found in many plants and microbial products. Like dextrans, they are formed as an undesirable by-product of sugar juice processing. On the other hand, levans, which can only be produced from sucrose, have potential industrial applications as thickeners and encapsulating agents and could provide ...

For more than a century, medical investigators have sought to incriminate microorganisms in the cause of cancer. The first scientific evidence of such a relationship came in 1911, with the first successful induction of a tumor using a cell-free extract.

Carotenoids occur universally in photosynthetic organisms but sporadically in nonphotosynthetic bacteria and eukaryotes. The primordial carotenogenic organisms were cyanobacteria and eubacteria that carried out anoxygenic photosynthesis. The phylogeny of carotenogenic organisms is evaluated to describe groups of organisms which could serve as sources ...
