Seeds of rape (Brassica napus L.) were germinated at various NaCl concentrations up to 200 mM. Germinating levels, seedling growth, triacylglycerol mobilization and lipase activity were investigated. High salt concentrations resulted in retardation of seed germination. Seedling growth as measured by radicle length was severely reduced by NaCl doses higher than 50 mM. Moreover, the mobilization ...

A number of coagulase-negative staphylococci isolated from human skin were found to produce lipase. Lipolytic activity appeared in the growth medium during the stationary phase of growth but did not appear as a result of autolysis of the cells. Maximal lipase synthesis was obtained when the medium was adjusted to pH 7.5 before inoculation. The purified enzyme hydrolyzed tributyrin and tridecano...

A method is described for turbidimetric assay of Iipase activity. The substrate is a two-phase emulsion composed of a fairly homogenous dispersion of micelles of either triolein or olive oil. The de-emulsification of the substrate after lipase addition is a true measure of the enzymatic activity. Turbidity change is related to amount of the enzyme by use of a commercial standard, purified lipas...
