Encapsulacion de una bacteria con potencial bioestimulante

Abstract

La actual necesidad de promover una agricultura más sostenible basada en productos ecológicos demanda el uso de bioestimulantes microbianos como alternativa a los fertilizantes y fitosanitarios convencionales. Se ha estudiado que el uso de los bioestimulantes microbianos favorecen a la mejora de la eficiencia nutricional y la tolerancia del estrés abiótico. Por estas razones, este proyecto se basó en un estudio de viabilidad para el desarrollo de un bioestimulante microbiano encapsulado en formato gránulo dispersable en agua (WG) empleando tecnología de lecho fluido. Para poder alcanzar este objetivo en una primera etapa se prepararon una serie de premezclas líquidas que contenían la bacteria de interés y los materiales de recubrimiento. Posteriormente, estas premezclas líquidas se sometieron a un proceso de secado en un granulador de lecho fluido para obtener producto WG. Como resultado de este trabajo, se obtuvieron tres prototipos de bioestimulante microbiano (WG_180523, WG_230523 y WG_060623) que mostraron cumplir con las especificaciones de propiedades fisicoquímicas según la normativa CIPAC. Por otro lado, cabe destacar que el proceso de encapsulación de la bacteria mediante secado por lecho fluido ha mostrado no afectar a su viabilidad.

La necessitat actual de promoure una agricultura més sostenible basada en productes ecològics demanda l'ús de bioestimulants microbians com a alternativa als fertilitzants i fitosanitaris convencionals. S'ha estudiat que l'ús dels bioestimulants microbians afavoreix la millora de l'eficiència nutricional i la tolerància de l'estrès abiòtic. Per aquestes raons, aquest projecte es va basar en un estudi de viabilitat per desenvolupar un bioestimulant microbià encapsulat en format grànul dispersable en aigua (WG) emprant tecnologia de llit fluid. Per poder assolir aquest objectiu en una primera etapa, es van preparar una sèrie de premescles líquides que contenien el bacteri d'interès i els materials de recobriment. Posteriorment, aquestes premescles líquides es van sotmetre a un procés d'assecatge en un granulador de llit fluid per obtenir producte WG. Com a resultat d'aquest treball, es van obtenir tres prototips de bioestimulant microbià (WG_180523, WG_230523 i WG_060623) que van mostrar complir les especificacions de propietats fisicoquímiques segons la normativa CIPAC. D'altra banda, cal destacar que el procés d'encapsulació del bacteri mitjançant assecat per llit fluid ha mostrat no afectar-ne la viabilitat.

The current need to promote a more sustainable agriculture based on organic products demands the use of microbial biostimulants as an alternative to conventional fertilizers and plant protection products. The use of microbial biostimulants has been studied to improve nutritional efficiency and abiotic stress tolerance. For these reasons, this project was based on a viability study for the development of a microbial biostimulant encapsulated in a water dispersible granule (WG) format using fluidised bed technology. In order to achieve this objective, a series of liquid premixes containing the bacteria of interest and the coating materials were prepared in a first stage. Subsequently, these liquid premixes were subjected to a drying process in a fluidised bed granulator to obtain WG product. As a result of this work, three prototypes of microbial biostimulants were obtained (WG_180523, WG_230523 and WG_060623) that showed to have the physicochemical property specifications according to CIPAC standards. On the other hand, it should be noted that the encapsulation process of the bacteria by fluid bed drying did not show to affect their viability.
