Abstract: Method for making surface water drinkable, which method is aimed at reducing the suspended matter content, turbidity, organic matter content and colour of the water, and is characterised in that it comprises: ?a step of nanofiltering the water (2) through at least one nanofiltration membrane (2) which has a breakdown capacity between 800 Da and 2000 Da, preferably between 800 and 1000 Da, the nanofiltration step leading to the acquisition of a permeate (7) and a concentrate (5), ?wherein the nanofiltration step is carried out with a conversion rate greater than 95%, ?the method being carried out without any step of adding an anti-scaling agent or any step of remineralising the permeate.

Abstract: The present invention provides a method for enhancing N-acetylglucosamine production by usage of a recombinant Bacillus subtilis with a glcK knockout. This invention enhanced the production of GlcNAc by knocking out the glcK gene which encodes a glucokinase, thus eliminating the GlcNAc phosphorylation to GlcNAc-6-P. The specific growth rate and content of GlcNAc in the supernatant of the recombinant Bacillus subtilis with the glcK knockout were 0.15 h?1 and 3.0 g/L, respectively, which were 2.32 times and 2.14 times of those of the control strain without glcK knockout. The recombinant Bacillus subtilis of the present invention would be potentially useful for industrial production of GlcNAc.

Abstract: The present invention is directed to novel genes mediating the carbon catabolite repression (CCR) of gluconeogenic genes. Furthermore, the polypeptides encoded by said genes as well as the use of said genes in a process for the production of a target fermentation product is provided. Processes for generating such microorganisms are also provided by the present invention. The invention is also related to a genetically engineered microorganism and its use for the production of a target fermentation product, wherein the gluconeogenic genes are relieved from CCR within said microorganism.

Abstract: Plasmid vectors for expression in Caenorhabditis elegans harbouring a heat inducible promoter nucleotide sequence, a synthetic intron nucleotide sequence optionally containing a Shine-Dalgarno sequence for efficient shuttling between C. elegans and E. coli, optionally a nucleotide sequence coding for a nuclear localisation signal or secretion signal, a nucleotide sequence coding for a recognisable tag, optionally a nucleotide sequence coding for a fluorescent protein, a nucleotide sequence coding for a protease cleavage site, a multiple cloning site containing a nucleotide sequence coding for an eukaryotic, such as human, protein or a nucleic acid molecule and a nucleotide sequence coding for termination of translation, are described. Methods of particularly large scale production of eukaryotic, such as human, proteins and nucleic acid molecules in nematodes are also described. The methods comprise injection one or several different plasmid vectors into the gonad of C.

Abstract: In a process for the partial desalination of water, especially of drinking water, with a mixture of weakly acid cation exchangers and strongly basic anion exchangers, whereby the charged ion exchangers are regenerated by CO.sub.2 -containing water, if required, with the addition of CaCO.sub.3, CaCO.sub.3 /MgO, Ca(OH).sub.2 or the like. Simultaneous with the partial desalination, the organic carbon compounds present in the water are reduced, whereby the charged ion exchangers are intermittently regenerated with HCl, NaCl, NaOH, or a mixture of NaCl and NaOH.

Abstract: A dental apparatus is provided with a group of standard preparation instruments that are held in deposit devices having sensors allocated to each device to determine the configuration and deposit condition of the preparation instrument in the deposit device, the apparatus has a second group of non-preparation instruments which include image-acquiring instruments for diagnostic purposes. Both instrument groups or types share a personal computer with a keyboard and a monitor in common through one interface data where the instrument-related functions can be read in and read out so that the installed program of the personal computer is activated dependent on the particular instrument being used.
