Abstract: Novel methods for biodegrading nitroaromatic compounds present as contaminants in soil or water using microorganisms are disclosed. Water is treatable directly; dry soil is first converted into a fluid medium by addition of water. The preferred method comprises two stages, each employing microorganisms: a fermentative stage, followed by an anaerobic stage. The fermentative stage is rapid, wherein an inoculum of aerobic and/or facultative microorganisms ferments a carbohydrate added to the fluid medium, exhausting the oxygen in the fluid medium and thereby inhibiting oxidative polymerization of amino by-products of the nitroaromatics. In the subsequent anaerobic stage, an inoculum of a mixed population of anaerobic microorganisms completes the mineralization of the contaminant nitroaromatics, using the remaining carbohydrate as a carbon and energy source. Preferably, the carbohydrate is a starch and the aerobic and/or facultative microorganisms are amylolytic, which cleave the starch at a moderate rate throughout both stages, ensuring a sustained supply of metabolizable carbohydrate. The microorganisms are preferably selected to be resistant to the types and concentrations of nitroaromatics present as contaminants.

Abstract: The process for the preparation of a purified solution of inulin from chicory juice consists in preliming the chicory juice to a pH not exceeding 11 and in then liming and carbonating it simultaneously and so that the pH of the juice does not exceed 11. The preliming makes it possible to obtain a juice which is easily filtrable and separable, whereas, by conducting the liming and carbonation simultaneously, this can be done at a relatively moderate pH, which minimises the losses of inulin due to its decomposition and to the decomposition of fructose and glucose.

Date Nov. 24, 1994Process for the preparation of complexes of iodine with chitosan or derivatives thereof, and the iodinated compounds thus obtainable. Said compounds take form of powders, which may contain over 60% of iodine in its elementary form. In a dry state the iodine bound to the chitosan or derivatives thereof does not sublimate. If the percentage content of iodine does not exceed 50 % (by weight), said powders can be dissolved in aqueous solvents of an acid type, such as, for example, diluted acetic acid or glutamic acid. Said solutions are compatible with addition of surfactants, preferably of a non-ionic type, which improve the solubility of the chitosan-iodine complex. Solutions with identical characteristics can, alternatively, be prepared by solubilizing, heating if necessary the iodine in a suitable surfactant, preferably non-ionic, and adding this solution under rapid stirring to the chitosan derivatives thereof, dissolved in water, optionally in the presence of acids or salts. Alternatively, the chitosan or derivatives thereof in a dry state can be added to the solution of iodine in surfactant which rapidly absorbs onto the solid, forming the chitosan-iodine complexes. This material suspended in water or in acid solutions, preferably acetic acid or glutamic acid, solubilizes rapidly. The complexes of iodine with chitosan or derivatives thereof, in the form of aspersable powders, solutions or ointments, thanks to their disinfectant and cicatrizing properties, can be used in the field of surgery post-operative treatment and more generally speaking as products for topical use for medication of wounds and disinfectation of the skin. Another area of interest in which the complexes can be used as an active principle is the field of cosmetics.

Abstract: This invention relates to a process for amplifying a specific nucleic acid sequence or its complement at a relatively constant temperature and without serial addition of reagents. The process provides in a single reaction medium an RNA polymerase, DNA polymerase, a ribonuclease that hydrolyses RNA of an RNA-DNA hybrid without hydrolysing single or double-stranded RNA or DNA, and ribonucleoside and deoxyribonucleoside triphosphates. The process then provides an RNA first template in the reaction medium. The RNA first template comprises a sequence complementary to a specific nucleic acid sequence, minus-sense sequences for a promoter and initiation site that are recognized by the RNA polymerase, and a 5'-terminal sequence that is complementary to at least the minus-sense sequence of the initiation site. Thus, the RNA first template has an inverted repeat sequence which could fold into a 5'-terminal stem-loop structure. The DNA polymerase uses the RNA first template to synthesize a DNA second template that together comprise an RNA-DNA hybrid. The DNA second template has plus-sense sequences of the promoter and the initiation site, and a 3'-terminal priming sequence that is complementary to the plus-sense sequence of the initiation site. The ribonuclease then hydrolyses an RNA which comprises the RNA-DNA hybrid, allowing the 3'-terminal priming sequence to hybridize to the plus-sense sequence of the initiation site in the DNA second template. The DNA polymerase then uses the DNA second template to synthesize the promoter by extending the 3'-terminal priming sequence of the DNA second template. The resulting partially double-stranded DNA has a promoter oriented toward the apex of a stem-loop structure. The RNA polymerase then recognizes the promoter and transcribes the DNA second template, thereby providing copies of the RNA first template. The process thereafter maintains the reaction conditions for a time sufficient to achieve a desired amplification of the specific nucleic acid sequence or its complement. This invention includes a kit containing the reagents of this invention.
