Title: Prodn. of butane 2,3-di ol by batch fermentation of molasses - with inhibition of cell growth after complete uptake of carbohydrate
Inventor: AFSCHAR ABBAS S DIPL CHEM DR
IPC: C12P7/18
Filed: 1990-05-28
Abstract: In prodn. of 2,3-butane diol by batch fermentation of a substrate contg. carbohydrate, using a microorganism producing 2,3-butane diol with O2 limitation, the substrate is molasses, cell growth is inhibited after complete uptake of carbohydrate and 2,3-butane diol is recovered opt. with sepn. of the cells from the medium. The substrate may be added batchwise (substrate-shift), e.g. in 2 or 3 portions. The initial substrate concn. is more than 100 g of carbohydrate/l, and is opt. raised further after a cell concn. of at least 3 g of cell dry matter/l has been rached. Growth may be inhibited by addn. of an inhibitor, esp. not less than 10 g/l of ethanol, and opt. also by breaking off the feed of medium contg. O2, e.g. air or O2. After the ending of the batch fermentation and inhibition of cell growth, the cells are sepd. from the medium and used again in the process, opt. after addn. of a growth inhibitor and breaking off the O2 feed. The renewed process may be without substrate-shift. USE/ADVANTAGE - Yield of 2,3-butane diol (I) is better, e.g. using substrate-shift the yield is 95.2-98.6 g (I)/l and 2.4-4.3 g acetoin/l, at a diol productivity of 1.0-1.1 g/l/h (96-100% of theory).

Patent DE-4023458-A1 (DE)
Inventor: VETTER ROMAN DIPL BIOL DR
IPC: C12N15/09
Filed: 1990-07-24
Abstract: Optimised high-alkaline proteases which are suitable for use in detergent formulations are described. They are prepared by employing mutated DNA sequences of transformed microorganisms. These DNA sequences are obtained by starting from DNA sequences which code for the high-alkaline protease which is normally produced by Bacillus species, modifying these DNA sequences in defined positions by directed mutagenesis (point mutation) in such a way that the codon in which the point mutation is located now codes for an amino acid which is more strongly basic than the original amino acid. The original amino acids have been replaced in the resulting high-alkaline proteases by more strongly basic amino acids, preferably by the amino acids lysine or arginine. Synthetic oligonucleotides, DNA sequences, vectors and transformed microorganisms used to generate and obtain the optimised high-alkaline protease are likewise described.

Inventor: KUHN THOMAS DIPL ING
IPC: G05B19/19
Filed: 1990-12-12
Abstract: Proposed is a method of determining parameters for the pilot-control of the position-control signal for one axis of a machine tool with numerical continuous-path control.
