Waste water and/or outgoing air are purified by contact with a polyurethane hydrogel containing surface active coal, a polymer having cationic groups and cells having enzymatic activity and being capable of growth.

Biologically active composition for purifying waste water and outgoing

A biologically active composition is prepared comprising a polyurethane hydrogel containing surface active coal, a polymer having cationic groups and cells having enzymatic activity and being capable of growth. The composition is used for purifying waste water and outgoing air.

Immobilization of cells in polyurethane hydrogel

A process for the production of a storage-stable preparation of micro-organisms, starting from a mixed culture of micro-organisms, which is capable to degrade products of industrial organic syntheses, which comprises that the culture conditions of an active mixed culture enriched in the customary manner are optimized, with the addition of the product to be degraded, in the customary manner according to the rate of degradation of the product and this mixed culture is converted in at least two passes into a stabilized activated mixed culture under the optimum conditions thus determined, and the culture thereby obtained is rendered storage-stable, its activity being maintained.

Preparations of micro-organisms

According to the present invention inhibitors for glycoside hydrolases, and in particular glucosidase inhibitors especially saccharase inhibitors, which are active in the digestive tract are formed by culturing organisms of the family Bacillaceae, particularly by strains of the genus Bacillus. It has also been found that certain strains of organisms of the family Bacillaceae, especially strains DSM 7, DSM 704 and DSM 675 produce the antibiotic known as 1-desoxynojirimycin. The invention therefore provides a method of producing 1-desoxynojirimycin which comprises culturing a 1-desoxynojirimycin producing organism of the genus Bacillus. Inhibitors for glycoside hydrolases and the invention includes methods for producing such inhibitors, pharmaceutical compositions containing the inhibitors and methods of treatment involving the use of the inhibitors.

Inhibitors, obtained from bacilli, for glycoside hydrolases

The invention relates to a novel process for the production of 1-desoxynojirimycin which involves culturing an organism of the Bacillaceae family in a nutrient solution as a temperature of about 15.degree. to 80.degree. C. in a fermentation vessel, whilst aerating and then isolating the 1-desoxynojirimycin, said nutrient solution containing sorbitol as the source of carbon.

Production of 1-desoxynojirimicin

A herbicidally active compound of the empirical formula C.sub.10 H.sub.14 N.sub.6 O.sub.3, exhibiting substantially the IR KBr-absorption spectrum shown in FIG. 2, is produced by aerobic culturing of a micro-organism of the family of the Actinoplanaceae under aerobic conditions in a nutrient medium which contains an assimilable carbon source, at least one assimilable nitrogen source and mineral salts, at a pH of 6 to 8 and a temperature of 20.degree. to 40.degree. C.

Glucopyranosyl and oligoglucosidyl derivatives of 4,6-bisdesoxy-4-(4,5,6-trihydroxy-3-hydroxymethylcyclohex-2-en-1-ylamino)- .alpha.-D-glucopyranose, which are inhibitors of glycoside hydrolases of the digestive tract, favorably improve the meat:fat ratio in animals in favor of a higher proportion of meat. A single amino-sugar or a mixture of amino-sugars can be formulated in combination with an edible carrier and fed to animals. A representative embodiment is a pig feedstuff in admixture with O-{4,6-bisdesoxy-4-[lS-(1,4,6/5)-4,5,6-trihydroxy-3-hydroxymethylcyclohex- 2-en-1-ylamino]-.alpha.-D-glucopyranoxyl}-(1.fwdarw.4)-O-.alpha.-D-glucopyr anosyl-(1.fwdarw.4)-D-glucopyranose.

Amino sugars and their use in improving the meat:fat ratio in animals

New amino sugars which are glucopyranosyl and oligoglucosidyl derivatives of 4,6-bisdesoxy-4-(4,5,6-trihydroxy-3-hydroxymethylcyclohex-2-en-1-ylamin o)-.alpha.-D-glucopyranose inhibit glycoside hydrolases of the digestive tract. The compounds, of which O-{4,6-bisdesoxy-4-[1S-(1,4,6/5)-4,5,6-trihydroxy-3-hydroxymethylcyclohex- 2-en-1-ylamino]-.alpha.-D-glucopyranosyl}-(1.fwdarw.4)-O-.alpha.-D-glucopyr anosyl-(1.fwdarw.4)-D-glucopyranose is a representative embodiment, demonstrate both saccharase and amylase inhibiting properties.
