Plant biostimulants are products that contain multiple compounds and claim to activate a wide range of plant responses. Amino acids based products are one example of biostimulants with a complex composition and different product characteristics depending on their sources and production processes. Bioibérica has differentiated their products by the high quality of their components and the way they perform a specific action in plant physiology. Amino acid biostimulants are obtained mainly by ...

Plant biostimulants are products that contain multiple compounds and claim toactivate a wide range of plant responses. Amino acid based products are one exampleof biostimulants with a complex composition and different product characteristicsdepending on their sources and production processes. Amino acid biostimulants areobtained mainly by chemical or enzymatic protein hydrolysis and the type ofhydrolysis determine the content of free amino acids and their enantiomeric purity.While L-amino ac...

Several environmental factors adversely affect plant growth, its development and the final crop yield, being temperature stress (cold, freeze or heat stress) one of the most limiting variables. With the aim to assess the effect of exogenous amino acids treatments, several experiments with plants subjected to different stressing temperatures were conducted applying an amino acid product obtained by Enzymatic Hydrolysis (Terra-Sorb). Findings suggest that Terra-Sorb has a similar effect than n...

Hydrolyzed protein fertilizers (HPFs) are obtained mainly by chemical hydrolysis, or through enzymatic hydrolysis, and they typically contain free amino acids, oligo- and poly-peptides.During the chemical hydrolysis, strong agents (acids or alkali) and high temperatures are used which should produce the L-amino acids racemization to their mirror image configuration leading to a loss in their biological activity.In the search for processes that do not induce racemization, enzymatic hydrolysis...

L-amino acids play a part in many physiological processes in plants. However, while L-amino acids are biologically active, the metabolism role of D-amino acids in plants is still doubtful, and the few existing studies on this topic indicate undesired agronomic effects. The enantiomeric separation of free amino acids contained in different hydrolyzed protein fertilizers used as biostimulants was achieved. Two capillary electrophoresis-tandem mass spectrometry (CE-MS2) methods were optimized i...
