(FR) PROCÉDÉ POUR L'OBTENTION, AU NIVEAU INDUSTRIEL, D'UN EXTRAIT CONCENTRÉ EN COMPOSÉS BIOPESTICIDES À PARTIR DE MICROALGUES ET/OU DE CYANOBACTÉRIES, L'EXTRAIT AINSI OBTENU ET SON UTILISATION
Abstract
(EN) The invention relates to a process for the extraction of compounds having inhibitory activity against the growth of phytopathogenic microorganisms from microalgae and/or cyanobacteria biomass, the extract thus obtained, and the use thereof as a biopesticide in agriculture. The process essentially comprises: obtaining a suspension of microalgal and/or cyanobacterial biomass at a given solid concentration; releasing the cellular content of the biomass by high-pressure homogenisation, operated at moderate pressure; extracting the biopesticidal components using a mixture of organic solvent, with a polarity between 0 and 9, and water; and separating the extract containing the biopesticidal components from the residual microalgal and/or cyanobacterial biomass using physical methods.
(ES) La invención proporciona un proceso de extracción de compuestos con actividad inhibidora del crecimiento de microorganismos fitopatógenos a partir de biomasa de microalgas y/o cianobacterias, el extracto así obtenido y el uso del mismo como bioplaguicida en agricultura. El proceso comprende esencialmente obtener una suspensión de biomasa de microalgas y/o cianobacterias a una concentración en sólidos determinada; liberar el contenido celular de la biomasa mediante homogeneización de alta presión, operado a una presión moderada; extraer los componentes bioplaguicidas empleando una mezcla de disolvente orgánico, con una polaridad comprendida entre 0 y 9, y agua; y separar el extracto que contiene los componentes bioplaguicidas de la biomasa de microalgas y/o cianobacterias residual por métodos físicos.
(FR) L'invention concerne un procédé d'extraction de composés à activité inhibitrice de la croissance de micro-organismes phytopathogènes à partir de la biomasse de microalgues et/ou de cyanobactéries, l'extrait ainsi obtenu et son utilisation comme biopesticide en agriculture. Le procédé consiste essentiellement à obtenir une suspension de biomasse de microalgues et/ou de cyanobactéries à une concentration en solides déterminée; à libérer le contenu cellulaire de la biomasse par homogénéisation haute pression, opérée à une pression modérée; à extraire les composés biopestides utilisant un mélange de dissolvant organique, avec une polarité comprise entre 0 et 9, et de l'eau; et à séparer l'extrait qui contient les composés biopesticides de la biomasse de microalgues et/ou de cyanobactéries résiduelle par des méthodes physiques.
