[Adsorption immobilization of alkaline lipase]. / Adsorbtsionnaia immobilizatsiia shchelochnoi lipazy.

A polyamide with the covalently coupled phosphatidyl ethanolamine was used for affinity adsorption of an alkaline lipase from Pseudomonas aeruginosa. The immobilization resulted in increase of the enzyme specific activity. Some properties of native and adsorbed enzyme were compared. The temperature optima, heat and pH stability, KM and Vmax values were determined for both native and immobilized enzymes.

[Biosynthesis of lipase by the mold fungus Rhizopus species, strain 3-3]. / Biosintez lipazy plesnevym gribom Rhizopus Species shtamm 3-3.

Cultivation of the microscopic fungus Rhizopus sp. str. 3-3--producer was investigated. Properties of lipase were studied. The technical preparation liparisopin G3x was obtained and examined. pH optimum of the preparation was within 6.0--7.0 and temperature optimum was 37 degrees C (olive oil used as substrate).
