A thiamine-auxotrophic strain of Zymomonas mobilis (CP4thi/pZY73), in which the alaD gene of Bacillus sphaericus coding for the alanine dehydrogenase was expressed, synthesizes and excretes alanine at high rates after thiamine starvation and in the presence of high external ammonium concentrations. The mechanism of alanine excretion was studied in this recombinant Zymomonas mobilis strain. Under production conditions the internal alanine concentration reached values of up to 280 mM and… Expand
Amino Acid Transport Systems in Biotechnologically Relevant Bacteria
Besides metabolic pathways and regulatory networks, transport reactions are also pivotal for understanding amino acid metabolism and production in bacteria. Apart from substrate uptake, this refersExpand
Genetic and physiological approaches for the production of amino acids
Knowledge of fundamental aspects of physiology, biochemistry, molecular biology and bioprocess engineering is described which must be optimized further in order to reach purposeful metabolic design of microorganisms capable of amino acid production. Expand
Zymomonas mobilis for the Conversion of Lignocellulosic Biomass to Fuels and Chemicals
Zymomonas mobilis is a promising organism for the production of biofuels from lignocellulosic biomass as it natively produces ethanol at high yields and at rates far greater than otherExpand

Structural and functional properties of the different classes of carrier systems from both prokaryotic and eukaryotic membranes are summarized and the methodical requirements for a quantitative measurement of their function and possible pitfalls in transport studies are described. Expand
Thermodynamics-based design of microbial cell factories for anaerobic product formation.
Using simple thermodynamic calculations, it is demonstrated that many products can theoretically be produced under anaerobic conditions using several conventional and non-conventional substrates. Expand


Expression of an L-alanine dehydrogenase gene in Zymomonas mobilis and excretion of L-alanine
An approach to broaden the product range of the ethanologenic, gram-negative bacterium Zymomonas mobilis by means of genetic engineering is presented, as alanine dehydrogenase activity was high and the excretion rate seemed to be a limiting factor. Expand
Lysine excretion by Corynebacterium glutamicum. 1. Identification of a specific secretion carrier system.
Lysine efflux was investigated using selected mutants which are not able to regulate lysine biosynthesis by feedback inhibition and follows Michaelis-Menten type kinetics, which rules out a previously suggested pore model. Expand
Lysine uptake and exchange in Corynebacterium glutamicum
Analysis of intracellular amino acid concentrations during the transport reaction as well as kinetic studies revealed that the observed uptake of lysine in fact represents a homologous antiport between extracellular [14C]lysine and intrACEllular unlabeled lysines. Expand
Mechanism of glutamate uptake in Zymomonas mobilis
A constitutive secondary glutamate uptake system is investigated that can be used as a nitrogen source for Z. mobilis and taken up by a symport with two H+ ions, leading to substantial accumulation in the cytosol at low pH values. Expand
Lysine secretion by wild-type Corynebacterium glutamicum triggered by dipeptide uptake
In Corynebacterium glutamicum peptide uptake increases the internal concentration of amino acids and thus triggers amino acid secretion and indicates that protein synthesis is necessary for this regulatory process. Expand
Uptake of glutamate in Corynebacterium glutamicum. 2. Evidence for a primary active transport system.
The inducible glutamate uptake system in Corynebacterium glutamicum was characterized with respect to its mechanism and energy coupling and it was found that changes in membrane potential and uptake activity cannot be separated, no correlation between these two parameters is observed. Expand
Proline excretion by Escherichia coli K12
Data reveal that genetic lesions eliminating active uptake can be used to specifically enhance metabolite excretion from proline overproducing strains of E. coli K12 and show that uncontrolled synthesis is not sufficient to cause excretion of this amino acid. Expand
Carrier-mediated glutamate secretion by Corynebacterium glutamicum under biotin limitation.
Under conditions leading to variation of glutamate secretion activity, a correlation of secretion rate and the intracellular ATP-pool was observed and ATP or a related high-energy metabolite is thought to be involved in the activity of the glutamate secretion system. Expand
Extracellular Formation of Alanine by Anaerobes
The possibility of extracellular formation of amino acids by anaerobes was investigated. In general, anaerobes were able to produce 20 to 50 mg of alanine per dl of medium extracellularly.Expand
Content and composition of hopanoids in Zymomonas mobilis under various growth conditions
By using a new method for quantification of the different hopanoid derivatives, a total hopanoid content of about 30 mg/g (dry cell weight) was observed in Zymomonas mobilis. This value is theExpand
