Mineralization of alanine enantiomers in soil treated with heavy metals and nutrients

Popis výsledku v původním jazyce

This work deals with the determination of the effect of heavy metals and nutrients applied to the soil on alanine enatiomers mineralization with the main focus on evaluating the eff ect on L/D alanine respiration rate ratio. This study was initiated because previous research works revealed a change in L/D amino acid respiration under acid- or heavy metal-stress in soil. Generally, D-amino acids artificially supplied to soil are less utilized by microorganisms compared with their L-enantiomers. Stress ofsoil microorganisms cause decreased discrimination of D-amino acids utilization. Also, previous research showed that an application of fertilizers or combinations of fertilizers may aff ect the mineralization rate of L-amino acids diff erently, comparedwith their D-enantiomers. The results of this study show, that the eff ect of both heavy metals and nutrients on the L/D ratio was not clear, increasing or decreasing this ratio.
