The effect of amino acid enantiomers on activity of selected enzymes in soil

To chci

This work was aimed to test the effect of selected amino acid enantiomers on activity of casein-protease and acid phosphomonoesterase in soil. Casein-protease was selected due to its key role in nitrogen mineralization and acid phosphomonoesterase due to its importance in soil organic P mineralization. The results showed that 5 mg of L- and D-glutamic acid added to fresh soil from Ah horizon of a moderately mown mountain meadow significantly decreased casein-protease activity, whereas alanine enantiomers slightly increased activity of this enzyme. Testing the effect of cystine on activity of acid phosphomonoesterase in soil showed slight increase of this activity after application of 3.2 mg L- or D-cystine to fresh soil (equivalent to 8 mg to dry soil). … celý popis
