Protein with phospholipase activity

This invention relates to a recombinant deoxyribonucleic acid (DNA) isolatable from Aspergillus, preferably Aspergillus foetidus, wherein it codes for a lysophospholipase (LPL) and has the nucleotide sequence for mature LPL stated in SEQ ID NO:1 or a nucleotide sequence derived therefrom, which hybridises under stringent conditions with the nucleotide sequence for mature LPL stated in SEQ ID NO:1. The invention also relates to vectors, to transformed host organisms and to processes for the production of LPL. The invention also provides enzyme products for the production of maltose syrup and products produced in this manner.

Lysophospholipase produced from aspergillus by recombinant methods

A novel xylanase, obtained from Bacillus subtilis strains, is provided which improves the consistency and increases the volume of bread and baked goods containing it. B. subtilis DSM 7147 containing the plasmid pIK 91 produces the xylanase. Genetic engineering insertion of the gene encoding the xylanase in the plasmid pUB110 is described.

Bacterial xylanase, method for its production, bacteria producing a

A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.
