  • Process for purifying and reusing surfactant-containing waste waters
    Patent number: 5885459
    Abstract: Waste water from a laundry (1) is collected in a storage container (3), fluffs and textile sheddings are separated through filtering sieves (2). The volume of the container is set so that it may store the amount of waste water produced for example during two days. The waste water is supplied with a bio-reactor (4) that works in aerobic conditions. Air is lead into the bio-reactor (4) at its lower end (5), establishing aerobic conditions therein. The biologically considered water leaves the bio-reactor (4) at the top end (6) of the column-shaped bio-reactor (4) and is supplied to an active coal column that acts as an adsorber (7). The adsorptively purified water leaves the adsorber (7) packed with active coal through the duct (8), is collected in a storage container (9) and if required is returned through duct (10) to the laundry, if required after 5 to 20% fresh water are added.

  • Deacetylase genes for the production of phosphinothricin or phosphin-othricyl-alanyl-alanine, process for their isolation, and their use
    Patent number: 5767371
    Abstract: Deacetylase genes for the production of phosphinothricin or phosphinothricyl-alanyl-alanine, processes for their isolation, and their use.The invention relates to deacetylase genes, to processes for their isolation, and to their use, in particular for the production of transgenic plants using tissue-specific promoters. It is possible to prevent the development of certain parts in these plants in a targeted manner. With the aid of deacetylase genes, it is furthermore possible to identify and isolate tissue-specific promoters in transgenic plants.
