Lipase Activity in Scallop Hepatopancreas

Removal of cadmium from scallop hepatopancreas by microbial processes.

A microbial process for removing cadmium from a homogenate of hepatopancreas, a waste of scallop processing, was devised to use this waste for value-added protein resources. Microorganisms were screened on the basis of the ability to remove cadmium from a medium with the initial concentration of 10 mg/l of cadmium. One soil isolate, identified as Xanthomonas sp. UR No. 2 by its taxonomical char...

Lipoprotein lipase and acid lipase activity in rabbit brain microvessels.

A preparation of cerebral microvessels was used to demonstrate the presence of lipoprotein lipase and acid lipase activity in the microvasculature of rabbit brain. Microvessels, consisting predominantly of capillaries, small arterioles, and venules, were islated from rabbit brain. Homogenates were assayed for lipolytic activity using a glycerol-stabilized trioleoylglycerol-phospholipid emulsion...

Lipase Activity of Mycoplasma.

Enzymatic activity of lipase

The knowledge of the digestive system of bullfrogs is an important step for the determination of their nutritional requirements throughout growth phases. With the objective of evaluating the enzymatic activity of lipase in the intestinal content of bullfrogs (Rana catesbeiana Shaw, 1802), 100 animals with median weight of 3.6 g were distributed in stalls under controlled temperature and photope...

Determination of lipase activity.

Heretofore most methods for the determination of lipase activity have employed emulsions of fatty acid esters in water (1). These emulsions have been stabilized by use of such agents as gum acacia. The disadvantages of such methods are that (1) the emulsions break up to a considerable and variable extent during the course of the incubation, and (2) the enzyme is presumed to be in the aqueous ph...
