Effet sur le maïs de l'application foliaire d'un sous-produit du processus d'élaboration de l'huile d'olive en deux étapes. L'objectif principal de ce travail était d'étudier l'effet de la fertilisation foliaire à doses différentes avec un sous-produit du processus d'élaboration de l'huile d'olive en deux étapes sur la production et qualité de...

The objective of this study was to investigate the effect of foliar fertilization of two biostimulants (BS1 and BS2) obtained from sewage sludge by fermentative processes using Bacillus licheniformis during four consecutive seasons in an olive tree crop applied at a dose of 6 L ha-1 divided into three applications (before flowering, beginning...

El objeto de la invención es obtener un producto a partir de hojas de tabaco (frescas y/o secas) desechadas para la fabricación del propio tabaco que actúen como en el campo agronómico como biofertilizante/bioestimulante. El proceso bioquímico seleccionad

Currently, the use of biostimulants is widespread in sustainable agriculture because they represent an alternative to chemical fertilizers. In this manuscript, we investigate the response of a greenhouse tomato crop grown in pots to a biostimulant obtained from slaughterhouse sludge applied continuously to the substrate under which the tomato...

The use of pesticides in agriculture is essential because it reduces the economic losses caused by pests, improving crop yields. In spite of the growing number of studies concerning the development and application of controlled release formulations (CRFs) of pesticides in agricultural soils, there are no studies about the effects of such...

Due to the important contribution that it makes to human nutrition, maize is one of the most widely-consumed cereals in the world. There is, therefore, high demand for fertilizers that will maintain maize production at both high yield and quality levels. The objective of this work was to study the effect of foliar fertilization using a...

There is currently a great deal of information available about the toxic effects of oxyfluorfen on soil biochemical activity and microbial biodiversity. However, there is no information about how this herbicide affects plant growth promoting bacteria (PGPB) or their properties, such as biofilm formation, nitrogen fixation, siderophore and auxin...

Currently, biostimulants obtained from protein hydrolysates are considered essential agronomic tools to promote sustainable agriculture without the use of chemical fertilizers. This study aimed to investigate the effectiveness of a biostimulant obtained from slaughterhouse sludge via enzymatic hydrolysis processes on green pepper crops in a...

Producto orgánico potenciador de la persistencia de atrazina en suelo y bioestimulante edafológico. La presente invención tiene por objeto un preparado líquido compuesto por una disolución a partes iguales de un extracto enzimático vegetal y un producto humectante a la que se añade atrazina en polvo hasta obtener una suspensión uniforme del 50%...

Polyurethane (PU) is a widely used polymer with a highly complex recycling process due to its chemical structure. Eliminating polyurethane is limited to incineration or accumulation in landfills. Biodegradation by enzymes and microorganisms has been studied for decades as an effective method of biological decomposition. In this study, Tenebrio...

The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation of polluted soils. In this manuscript we study under laboratory conditions the bioremediation capacity of a new biostimulant obtained from slaughterhouse sludge in a soil polluted by the oxyfluorfen at a rate of 4 l ha−1 (manufacturer's...

The biostimulant potential of three different organic acids (OAs) present in the rhizosphere, specifically lactic, oxalic, and citric acids, have been studied. The results showed a rapid and complete metabolism of these three acids with soil microorganisms using them as a source of carbon and energy. Biostimulation was confirmed by soil...

Bacillus licheniformis is a Gram-positive, soil bacterium used in the biotechnology industry to manufacture industrial enzymes including several proteases, amylase, lipases, chitinases, etc. These enzymes have a wide range of application in food and detergent industry. However, this organism may have other applications in the environmental...

The soil moisture content can vary the behavior of biochemical activity and its incidence on herbicides. The objective of this manuscript was to assess, under controlled laboratory conditions, whether a prolonged 75-day drought can affect the behavior of 4-chloro-2-methylphenoxyacetic acid (MCPA) herbicide and biochemical properties in three...

This work presents a new bioprocess process for the extraction of bioactive components from soy pulp by-product (okara) using an enzymatic technology that was compared to a conventional water extraction. Okara is rich in fiber, fat, protein, and bioactive compounds such as isoflavones but its low solubility hampers the use in food and...

Biostimulants are substances and/or microorganisms that are applied to plants or to the rhizosphere in order to enhance the natural process improving the absorption of nutrients and the quality of crops as well as the tolerance to abiotic stresses. A new biostimulant was developed from sewage sludge through its fermentation with Bacillus...

The use of biostimulants in the bioremediation of polluted soils in order to eliminate/reduce the toxic effects of pesticides on the soil is currently a very common environmental practice. In this study, we studied the bioremediation effect of three biostimulants obtained from sewage sludge by way of an enzymatic hydrolysis and fermentation...

Management of sewage sludge has become a topic of increasing importance. This is because the treatment and final destination of these wastes are not growing at the same rate at which generated what is necessary to add the limited storage capacity of wastewater treatment plants or waste transfer centers. Current policies of different governments...
