Reserve lipid degradation

The increase in glyoxysomal enzymatic activities of control cotyledons was paralleled with lipid degradation (1,2),These activities were maximal the first five days of seeds imbibition, afterwards they decreased considerably simultaneously to using up of lipid reserves. Salt delayed optimal activities of studied enzymes, this was paralleled with the decrease in lipidic reserve utilisation (1) NaCl concentration more than 2g/l inhibited paratially enzymes since their maximal activities were reduced in comparaison to control ones.

Other additives which facilitate degradation are vegetable oils (unsaturated lipids), and low molecular weight compounds, because they are inherently more accessible to chemical reactions. Eventually, when the molecular weight of the polymer is reduced to about 5000, biodegradation occurs. One reservation regarding the use of these additives is the potential toxic effects of heavy metal residues.
