Abstract: The invention relates to a process for the purification and, if desired, recovery of formate-dehydrogenase (FDH) from Candida boidinii, in which FDH is subjected to a phase distribution in an aqueous 2-phase system that contains a triazine dyestuff that is bonded to an inert water-soluble polymer.

Abstract: A microbiologically produced .alpha.-acetylamino cinnamic acid acylase and a method for its production from Brevibacterium species NCIB 12246 or NCIB 12247. The new enzyme can be used as constituent of a coupled enzyme system for enzymatic conversions which run via the intermediary stage .alpha.-imino-.beta.-phenylpropionic acid or phenylpyruvic acid.

Abstract: In a process and an apparatus for the bubble-free gassing of liquids, especially of culture media for propagating tissue cultures, in which process and apparatus a gas exchange occurs across an immersed membrane sheet, to achieve simple, effective and as uniform as possible a distribution of the gas introduction and gas desorption without mechanical damage to the liquid constituents, a tubular membrane cage formed by hollow membrane filaments is suspended flexibly in the medium to be gassed and moved in a circular oscillating movement without true rotation. The gassing rate is controlled by altering the angular oscillating movement frequency and/or the radius of the circular path, or alternatively by altering the gas concentration and/or the pressure of the gas flowing into the membrane cage.

Abstract: The invention concerns a double-stranded recombinant DNA cloning vector comprising one single insertion site for foreign DNA and one or two labelling sites adjacent or approximate to said insertion site. In the instance of two labelling sites, said sites flank the insertion site. The labelling site(s) can be individually labelled in a fashion that results in the labelling of the 3' end of either strand. The use of the invention in a process affords the ability to individually label only one strand at the 3' end in a simplified method for base sequencing analysis.

Abstract: Pyocyanine compounds of the formula: ##STR1## wherein R.sup.1 represents one of the formula --C.sub.1-10 -alkylene-CO.sub.2 -C.sub.1-5 -alkyl;--C.sub.1-10 -alkylene-CO.sub.2 H; and ##STR2## R.sup.2 represents hydrogen or C.sub.1-2 -alkyl and R.sup.1 is attached to the 7 or 8 aromatic ring position. The compounds are useful antibiotics.

Abstract: The invention concerns the intercistronic DNA sequence of the atp operon of Escherichia coli for the subunit c of the ATP synthase, a DNA structure and an expression vector which are characterized by the said intercistronic DNA sequence, and a process for the production of proteins using the same. The DNA sequence enhances the rate of synthesis of the proteins.

Abstract: The present invention relates to a process for the simultaneous synthesis of several oligonucleotides on a solid phase by using supports of flat material. Finally, the present invention relates to an apparatus for carrying out said process.

Abstract: The invention relates to 2'-deoxy-3'-phosphonylmethyl nucleosides that are not substituted in the 2'-position.

Abstract: The invention relates to a process for the manufacture of p-menth-8-ene-1,2-diol by the microbiological conversion of limonene in the presence of various fungi.

Abstract: Oil polluted water or solid adsorbents are treated with microbially produced glycolipids to separate the oil phase. The treatment may be carried out in an apparatus which can be taken to the site and which comprises a mixing vessel supported by an undercarriage and provided with a storage container to supply the glycolipids, filling means, overflow discharge means and outlet means at its base.

Abstract: The invention relates to a process for fermenting carbohydrate- and phosphate-containing liquid media with limitation of phosphate with bacteria capable of forming butanol, acetone and/or ethanol as fermentation products performed with a total phosphate content in the medium of 1.0 to 0.4 mmoles.

Abstract: A process for the production of adenine ring system containing co-enzymes bound to a macro-molecular carrier comprising the steps of alkylating an adenine ring system containing co-enzyme in the 1 position with an alkylating agent containing a terminal group capable of reacting with said macro-molecular carrier selected from the group consisting of carboxyl, amine and vinyl, reacting said alkylated co-enzyme with a macro-molecular carrier having groups capable of reacting with said terminal groups, subjecting said alkylated co-enzyme bound to a macro-molecular carrier to a Dimroth rearrangement into the N.sup.6 -form of alkylation, and recovering said adenine ring system containing co-enzyme bound to a macro-molecular carrier.

Abstract: A method and process for preventing the penetration and/or adhesion of hydrocarbons such as crude oil or mineral oil-hydrocarbons into or respectively on objects. The natural and/or constructed objects are sprayed with an aqueous solution and/or dispersion of glycolipids resulting in a thin layer covering the object. A hydrocarbon composition can contact the sprayed object and the resulting hydrocarbon; containing mass can be removed with a pressurized water jet. Various ways exist for degrading or separating the hydrocarbons from the run-off. Preferably the aqueous solution and/or dispersion is treated with ultrasonics before being applied to the surfaces of the objects.

Abstract: A process in which phenolic substances, particularly lignin sulfonate, are used to produce a binder for wood materials. The phenolic substance is activated by displacing it with enzymes. Phenolic groups of the phenolic substance become oxidatively polymerized by a radical mechanism, so that the phenolic substance is changed into an active binder.

Abstract: This invention relates to phosphorus-containing compounds having the formula: ##STR1## wherein A=O or S, Z=O or S and X and Y=various substituents.

Abstract: A process for obtaining metal-free corrinoids consisting of inoculating a culture media free of added compounds of metals of the VIIIth group of the Periodic Table with a parent strain of Rhodopseudomonas, cultivating under illumination, repeating the steps of inoculating and cultivating employing said culture media and said illumination employing a part of the sequential culture from the preceding stage as an inoculum in each subsequent state, for a series of several pre-production culture stages, inoculating said culture media with the preceding sequential culture for the last time, cultivating under illumination, separating the microorganism from the culture media of the production culture stage and isolating metal-free corrinoids from the culture media of the production culture stage.

Abstract: Oils or petroleum hydrocarbons are separated from solid or solid/liquid mixtures thereof with soil, sand or oil processing residues, by treating these oil-containing mixtures with an aqueous solution or dispersion of a crude extract of microbially produced glycolipids and separating the oil-containing phase from the aqueous phase.
