摘要: A microbiological assay for chemicals, which uses a cell and a reducing dye to quantitatively measure inhibition of electron transport in the cell membrane as a function of chemicals in the substance being tested, is disclosed. This assay and method is reliable, simple, fast, and inexpensive, requires a minimum amount of durable equipment, and avoids the need for the use of live animals as the indicator organisms. The assay is particularly useful for testing for toxicity in food products, environmental, medical and industrial processes, sewage treatment, effluent, agricultural wastes, and chemical dumps.

摘要: A .beta.-fructofuranosidase with a molecular weight of 49,000.+-.5,000 daltons on SDS-PAGE, an isoelectric point of 4.6.+-.0.5, an optimum pH of about 5.5-6.0, and an optimum temperature of about 50.degree. C. in the presence of calcium ion. The enzyme acts on saccharides with a .beta.-fructofuranosidic linkage and other substances including other saccharides, sugar alcohols, and alcohols to produce fructosyl-transferred saccharides in a relatively high yield.
