摘要:
A stable and water-insoluble immobilized lactase having a high lactose-hydrolyzing activity is produced with industrial advantages by immobilizing a lactase derived from Aspergillus oryzae on a macroporous phenol-formaldehyde anion-exchange resin. The immobilized lactase can be used in the continuous enzymatic hydrolysis of lactose in milk, whey and whey permeate.

Liposomes cytotoxic to virus-infected cells which comprises as membrane constituents a phosphatidylcholine having phase-transition temperature of below 37°C, an acidic phospholipid, and cholesterol. Similar liposomes which additionally comprise a phospholipid linked to a peptide possessing anti-HIV activity, said peptide comprising an amino acid sequence: Asn-Phe-Pro-Leu-Ile-Ile-Lys-Asn-Leu-Lys-Ile- Glu-Asp-Ser-Asp-Thr-Tyr-Ile-Cys-Glu-Val-Glu- Asp-Gln-Lys-Glu-Glu wherein the Cys residue is L-cysteine, or S -benzylated or S -acetamidomethylated derivative of L-cysteine.

摘要:
Previously, no immobilised lactase was both stable and highly active to lactose. This problem is now overcome with a stable and water-insoluble immobilized lactase prepared by immobilizing a lactase derived from Aspergillus oryzae on a macroporous amphoteric phenolformaldehyde type ion-exchange resin. The immobilized lactase can be employed in the continuous hydrolysis of lactose in milk and whey.
