Biostimulants

The Polyamine's Lab develops innovative microbial-based biostimulants and biopesticides that enhance crop productivity and stress tolerance, while reducing the chemical inputs in agriculture. These solutions help crops better withstand environmental challenges, both abiotic and biotic, promoting growth and yield.

Our research aims to contribute to climate-smart and sustainable agriculture by providing multifunctional biostimulants and biopesticides.

We design and develop next-generation biostimulants and biopesticides based on multifunctional plant-associated microorganisms. These microbial products not only promote plant-growth, yield and fruit quality attributes, but also enhance tolerance and resistance to various abiotic and biotic stresses. Our microbial solutions aim to enhance resilience to abiotic stress (e.g., drought, salinity, cold/freezing), and to improve plant defenses against different types of pathogens (fungal, bacterial and parasitic).

What Makes Us Unique

Microbial Biobank. We house a diverse collection of over 6,000 bacterial root associated isolates, offering a rich resource for research and innovation in plant-microbe interactions.
Multifunctional Microorganisms. Our strains are selected and developed for plant growth promotion, yield enhancement, multi-stress tolerance, and priming of plant defenses, making them powerful tools for sustainable agriculture.
Integrated Expertise. We bridge microbial biotechnology, plant-microbe interaction research, and agronomy, ensuring a holistic approach from lab to field.
Specialized Knowledge in Plant Metabolism. Our team brings deep expertise in plant metabolism, including regulators of stress responses and immune modulation in plants.
End-to-End Capabilities. From bacterial isolation and characterization to greenhouse and field trials, we offer a full-cycle development pipeline tailored to your needs.

PROYECTOS

DESARROLLO DE PRODUCTOS BIOESTIMULANTES BASADOS EN MICROORGANISMOS PARA LA PROTECCIÓN FRENTE A ESTRÉS ABIÓTICO EN CULTIVOS

Development of microbe-based biostimulant products to enhance abiotic stress tolerance in crops (BIOSTRESS) (2021-2023)

Los bioestimulantes aumentan la absorción de los nutrientes por la planta y aumentan la eficiencia en el uso de los mismos, reduciendo la necesidad de aplicar elevadas concentraciones de fertilizantes químicos en cultivos.

Con el objetivo de promover una agricultura sostenible en el contexto del cambio climático, nuestro laboratorio está desarrollando nuevos productos bioestimulantes basados en microorganismos, que se están ensayando en diferentes cultivos bajo diversas condiciones de estrés.

Este proyecto "Prueba de Concepto" de transferencia tecnológica se está desarrollando gracias a la financiación del Ministerio de Ciencia a Innovación y la Agencia Estatal de Investigación (PDC2021-121267-I00) en estrecha colaboración con la Oficina de Transferencia de Tecnología de la Universidad de Barcelona.

Nuestro laboratorio también colabora con empresas interesadas en el desarrollo de nuevos productos bioestimulantes basados en microorganismos.

Plant biostimulants improve nutrient uptake and use efficiency, thus reducing the need to apply high concentrations of chemical fertilizers. Aiming at the transition towards a more sustainable agriculture in the context of climate change, we're developing new microbe-based biostimulant products that are being tested in different crops under diverse stress conditions. This proof-of-concept project is being performed in close collaboration with the Transfer of Technology Office of the University of Barcelona.

Our lab is also collaborating with industrial partners interested in the development of new biostimulant products.
