Abstract: The present invention relates to a method for determination of numbers of croorganisms present in materials and for predicting their growth capability in the materials such as foodstuffs, growth media and in the presence of chemical agents. The invention also provides immobilizing cassettes and optical apparatus for use in this method.

Abstract: An heteropolysaccharide known as Biopolymer PS 87 comprises glucose, galactose, mannose, glucuronic acid and fucose. Biopolymer PS 87 is pseudoplastic, has a consistency at 20.degree. C. of at least 150 poise and a yield stress value at 20.degree. C. of at least 30 dynes/cm.sup.2. Biopolymer PS 87 is synthesized by a strain of Bacillus polymyxa or a genetically similar micro-organism and has many domestic and industrial uses as a suspending agent or thickener.

Abstract: A liquid bleach composition comprises a hydrogen peroxide precursor which includes as an enzyme an alcohol oxidase and as a substrate for the enzyme the corresponding alcohol, the enzyme and the substrate being incapable of substantial interaction in the composition. The composition contains less than 1 unit of catalase for every 2 units of the alcohol oxidase so that peroxide formation, when the composition is diluted with 100 times its volume of water to trigger the interaction of the enzyme and its substrate, it not substantially impaired. The diluted composition has a pH value of from 7.5 to 11. Preferably, the composition also comprises detergent active compound.

Abstract: Growth of bacteria belonging to new species of genera Pseudomonas, Microcyclus and Hyphomicrobium upon culture media comprising sources of assimilable carbon, for example oxygenated hydrocarbons, and inorganic nutrients to produce protein compositions and/or other fermentation products, for example amino acids. The protein compositions produced are suitable for use as protein supplements in human and animal foods.

Abstract: A process for treating single cell protein particularly of bacterial origin in order to reduce the nucleic acid content thereof and thereby render it more suitable for human consumption. The process involves subjecting a culture containing microorganism cells to three main steps namely, (A) treatment with acid to lower pH, (B) heating and (C) treatment with alkali to raise pH. The microorganism cells are thereafter removed from the culture medium.
