Did you know that there are microorganisms that can synthesize the same metabolites used by plants?

It is well known that, as they grow and develop, all plants consume, synthesize and release a wide variety of chemical substances, known as metabolites. These metabolites can be classified into two main types:

  • Primary, whose main function is to nourish, promote growth and facilitate plant reproduction.
  • Secondary, which are not essential for the life of the plant, but play an essential role in its ability to respond to environmental changes and adapt to the environment.

They are much more specific and sometimes exclusive to each species. They have fundamental roles in plant communication and adaptation, acting as germination inducers and repellents for herbivores and plants, preventing tissue oxidation and even protecting the crop against bacteria and fungi.

Therefore, it is logical to think that improvements in the crop development and resistance can be made by inducing or adding these metabolites at the appropriate phenological stages. 

Some of these metabolites, such as jasmonic acid and salicylic acid, are involved in the defence against pathogens, while others, such as ethylene, act in response to stress. Auxins, such as indolacetic acid, contribute to root development and formation. All these compounds can be supplied by rhizobia and microorganisms present in the soil.

You might be wondering how is this possible. Nature naturally selects those organisms that have the right tools to survive. Evolutionarily speaking, plants that developed symbiosis and close mutualism relationships with microorganisms producing these substances were favored and managed to survive.

At Herogra Especiales, we leverage the natural advantage provided by this type of rhizobia to generate bacterial metabolites with significant biostimulant potential.

To achieve this, we have developed exclusive cultivation and industrial scaling conditions for our rhizobia, which promote the production of a high concentration of metabolites.

Results are more than evident, even in the case of seeds. On the left, we can see the regular development of several untreated wheat seeds, and on the right the seeds treated with 0.5 mL/L of our product with microbial metabolites TOTEM. The effects translate into a greater number of secondary root hairs and increased root thickness.

The effects on berry crops, such as blackberries, are also prominent. The root development of the blackberry grown in pots without inoculation (left), compared to the root development of the crop with TOTEM (right), is highly significant.

Looking at the results with TOTEM, are you ready to try our ferments?
