A synthetic material – created from 1 billion nanomagnets – assumes different aggregate states depending on the temperature: the so-called metamaterial…
A first draft of the “tree of life” for the roughly 2.3 million named species of animals, plants, fungi and microbes — from platypuses to puffballs — has…
This is the first time that direct interspecies electron transport–the movement of electrons from a cell, through the external environment, to another cell…
In the established femtosecond laser-assisted in situ keratomileusis (fs LASIK), the cornea is cut open using the laser to subsequently correct the defective…
Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried have now identified a new mechanism that stabilizes specific RNA molecules and…
Limitation of natural sources, especially of fossil resources, for base material that is currently used to produce polyamides and related composites together with the increasing demand of these products, promotes the search for renewable sources of the base material. Fermentation by genetically engineered bacteria gains increasing interest as one of these possible sources.
Cadaverine is a biogenic amine that can be produced by Corynebacterium glutamicum from the amino acid lysine by heterologous expression of a lysine decarboxylase from Escherichia coli.
Overexpression of the patA and patD genes from Escherichia coli in Corynebacterium glutamicum enables the latter to further metabolize cadaverine to 5 aminovalerate (5AVA), which is a potential base material for the production of nylon 5 and a C5 platform for the synthesis of base materials for other polyamides.
Chemical industry is facing an increasing demand on polyamides and related composites, whereas in contrast the accessibility of base material from fossil sources for their production alleviates. Therefore, in seek for alternative and renewable sources, bacterial fermentation has become into focus in several chemical production areas. The offered invention provides such a source for nylon production and related composites.
Although today's highly precise satellites do a fine job of measuring the area of sea ice, measuring the volume has always been a tricky business.
U.S. farmers are growing fewer types of crops than they were 34 years ago, which could have implications for how farms fare as changes to the climate evolve,…
