Patent GB-489170-A (GB)
Title: Improvements relating to the production of fatty acids
IPC: C12P7/52
Filed: 1937-01-18
Abstract: Fatty acids, mainly butyric acid, are produced from the spent wash from butyl alcohol-acetone fermentation by inoculating the wash with a culture mainly of the type suitable for the production of butyric acid by the fermentation of saccharine mashes at temperatures of about 35-37 DEG  C. under controlled conditions of acidity, which culture may consist of the same form of bacillus as is used in the butyl alcohol-acetone fermentation resulting in the spent wash.  The process may be carried out by combining the processes described in Specifications 4845/15 and 164,366, [both in Class 2 (iii)], taken in that order.  The spent wash may be utilized as it comes straight from the butyl alcohol-acetone fermentation or after it has been enriched as regards its content of fermentable matter, e.g. by addition of fermentable matter, filtration or decantation followed by evaporation.  In an example, a molasses mash containing calcium superphosphate is sterilized, cooled to 37 DEG  C. and fermented to a finish by means of a rice mash culture of butyl alcohol-acetone producing organisms according to Specification 4845/15, the volatile solvents are separated, e.g. by distillation, the spent wash is mixed with calcium carbonate and fermented with a culture of butyric acid producing organisms, and the resulting volatile fatty acids are recovered in the form of their calcium salts.

Patent GB-725938-A (GB)
Title: Method of preparing substantially protein-free polysaccharides from micro-organisms
IPC: A61K35/74
Filed: 1953-01-20
Abstract: Substantially protein-and nucleic acid free polysaccharides are prepared by contacting the dried microorganisms or the moist sediment from bacterial cultures with a phenol-water mixture which is homogeneous at the temperature of substantially above 20 DEG C., e.g. 55 DEG -68 DEG C. which is used, cooling the mixture, say to 5-10 DEG C., to cause separation into an aqueous layer and a phenolic layer, removing the extracted bacteria, and treating the aqueous layer for the isolation of the polysaccharides.  A mixture of equal volumes of water and 75-90 per cent. phenol may be used for the extraction process.  Separation of the two layers is suitably effected in a centrifuge.  Treatment of the aqueous layer comprises the removal of phenol by dialysis or extraction with ether, concentration in vacuum, and addition to several times its volume of a water-miscible organic liquid, e.g. methanol, ethanol, acetone, which preferably contains alkali metal acetate, whereby a precipitate of polysaccharide containing nucleic acids is obtained.  It is purified by repeated fractional precipitation of concentrated aqueous solutions thereof, by means of water-miscible organic solvents, the nucleic acids being difficultly soluble in, for instance, 50 per cent. ethanol.  The polysaccharides in turn are precipitated by the addition of several times the volume of the solvents.  Alternatively, the nucleic acids may be removed by electrophoresis.  Gram-negative and -positive bacteria, molds, yeasts and other fungi may be treated according to the invention.  Aqueous or aqueous-alcoholic solutions, or syrups of the polysaccharides may be used for oral administration, or isotonic saline solutions for injection, as pyrogenic stimulating agents.  The solutions may also be mixed with solutions of bacterial proteins, the pH being then adjusted to 4.5 by acetic acid to produce antigens.
