Bioestimulantes y biopesticidas obtenidos de subproductos y coproductos alimenticios


Oferta Tecnológica
Un centro de investigación español ha desarrollado una metodología para aprovechar subproductos y coproductos alimenticios y producir bioestimulantes y biopesticidas. Mediante los procesos de fermentación adecuados, es posible obtener alternativas biológicas más económicas y ecológicas a los fertilizantes químicos. El uso de bioestimulantes y biofertilizantes ofrece las siguientes ventajas: 1) aumento de la productividad de los cultivos y de la tolerancia a factores de estrés, 2) sostenibilidad y marco jurídico, ya que se obtiene de fuentes renovables y son una alternativa a la síntesis química y 3) viabilidad de producción industrial. El centro busca cooperación técnica con socios del sector agroalimentario para mejorar la gestión de sus subproductos.


Biostimulants and biopesticides from food by-products and co-products
A Spanish research centre has developed a methodology to take advantage of food by-products and co-products to generate biostimulants and biopesticides. By means of suitable fermentation processes it is possible to generate biological alternatives to chemical fertilizers that are cheaper and environmentally friendly. The centre is interested in establishing technical cooperation agreements with industry to better manage their by-products.
Residues, by-products and effluents from the food industry may pose an environmental problem for society and business. Sometimes these residues contain a high organic load, and therefore require additional treatments.

An innovative initiative for the management of these products is to consider them as potential substrates in bioprocesses, leading to its recovery by obtaining industrially interesting products. The resulting products could be used by the company or devoted to marketing in different market sectors, such as the agronomic. Additionally, it should be considered that the use of these products as biotechnological alternative would result in a decrease in the organic load which would mean a reduction in management costs.

A Spanish research center has developed a methodology to exploit by-products or residues from the food industry and transform them into higher value products, such as bioelicitors or biofertilizers, by fermentation processes.

The methodology is based on designs ranging from design to product concept. Generally, by-products derived from the processing of vegetal raw materials meet a series of desired features to be considered as raw bioprocess materials. They are able to generate compounds of interest to industrial level subjects through fermentation processes. These raw materials are characterized by:
1. Low cost: they are generated as a consequence of a production process
2. They have the basic nutritional requirements that cover microorganisms necessities (the ones that are potential producers of substances of interest)
3. They require a few or non pre-treatment.
4. They are available through the year

The first phase of the methodology includes the analysis ot the commercial legal aptitude, the screening of functional aptitudes (theoretical), a pilot process development, pretreatment of the raw material and the stabilization if the generated product.

The next step includes the development of formulations, the stablishment of the maximum effective dose as well as the validation of products´ functionality (biopesticide, bioestimulant).

The growth of biopesticides is a growing trend worldwide. Europe leads it with new regulations, for instance France which has set itself that current use of traditional pesticides should be reduced by 50% by 2018.

Using bioestimulants / biofertilizer in crops has several advantages:
1. Increasing crop productivity and enhancing their tolerance to stressors.
2. Sustainability and legal framework, since they are obtained from renewable sources and they are alternative to chemical synthesis.
3. Industrial production viability

Industrial partners that are working in the agrofood sector and could be interested in taking profit from their by-products are sought. The developed methodology could transform a cost into a benefit through the fermentation of the mentioned by-products. By means of a technical cooperation the Centre could study industry´s profile (the centre previously asks the company about specific data) and therefore could adapt the fermentative processes to specific conditions to better manage the by-products; always with the aim of obtaining the largest benefits.
Advantages and Innovations:
Bioestimulants are increasingly used in conventional agriculture and can help solve crop losses.
1. Increasing crop productivity and enhancing their tolerance to stressors.
Vegetal bioestimulants or phytostimulants, regardless of its nutrient content, may contain substance (s), compound (s) and / or microorganisms, whose functional use, when applied to plants or the rhizosphere, involves improving crop development, vigor, yield and / or quality by stimulating natural processes that benefit the growth and the responses to biotic and / or abiotic stress.
2. Sustainability and legal framework
Bioestimulants can be obtained from renewable sources as an alternative to synthetic chemical fertilizers.
Besides the technical advantage of reducing environmental impact and extraction of substances for the enrichment of products/prototyping to develop, the main advantage is the possibility of formulating biostimulants products, which are not currently subject to a phytosanitary trade.
3. Industrial production viability
The approach is oriented to the maximum industrial feasibility from the beginning. It is achieved by using by-products and/or co-products from the food industry (molasses, effluent plants, canning of olive industry, slops, etc.) as a low-cost culture media and suitable microorganisms (usually isolated from ground) that are regularly involved in metabolic pathways of plants (bacteria, fungi, yeasts and / or free-living algae or lichen symbionts).

Partner sought

Type and Role of Partner Sought:
Agrofood industrial partners interested in taking profit from their by-products or effluents are soutght. Moreover, fertilizer companies that would like to diversify their business or agronomics enterprises that would like to less the dependance on chemical products. These partners are sought to establish a technical cooperation agreement.

In the framework of these agreements, companies will be helped by the centre to better take advantage of their by-products and therefore to get money from them. The centre will characterize the by-products and will identify the potential re-use as well as the products to be obtained. Moreover, the centre will define the processes and their performances
