The biostimulant potential of three different organic acids (OAs) present in the rhizosphere, specifically lactic, oxalic, and citric acids, have been studied. results showed a rapid complete metabolism these with soil microorganisms using them as source carbon energy. Biostimulation was confirmed by biochemical studies which an increase enzymatic activities, such dehydrogenase phosphatase, lactic being those that produced greatest biostimulation. With regard to microbiota composition,...
In this study, the presence of pesticide residues in foods, specifically tomatoes and potatoes, was investigated after harvesting Paute Canton-Ecuador. An information survey car-ried out to determine most relevant crops pesticides study area. A qualitative analysis organophosphates pyrethroids carried samples Solanum lycoper-sicum tuberosum using thin layer chromatography technique. It found that 80.00% tomato presented organophosphate compounds 30. 00% pyrethroid residues, while 66.7%...
Currently, the use of biostimulants is widespread in sustainable agriculture because they represent an alternative to chemical fertilizers. In this manuscript, we investigate response a greenhouse tomato crop grown pots biostimulant obtained from slaughterhouse sludge applied continuously substrate under which was or directly via foliar route. Two doses (0.7 and 1.4 g L−1), four times throughout growth period (120 days), were used. During period, height plants, number flowers fruits...
In multicellular organisms, cis -regulation controls gene expression in space and time. Despite the essential implication of development evolution organisms human diseases, our knowledge about regulatory sequences largely derives from analyzing their activity individually outside genomic context. Indeed, contribution these to target genes context is still unknown. Here we present a novel genetic screen designed visualize interrupt landscapes vertebrates. this screen, based on random...
Ozone is a destructive pollutant, damaging crops, and decreasing crop yield. Therefore, there great interest in finding strategies to alleviate ozone-induced losses. In plants, ozone enters leaves through the stomata immediately degraded into reactive oxygen species (ROS), producing ROS stress plants. can be controlled by ROS-scavenging systems that include enzymatic or non-enzymatic mechanisms. Our research group has developed product from rice bran, by-product of milling which bioactive...
Biostimulants are substances and/or microorganisms that applied to plants or the rhizosphere in order enhance natural process improving absorption of nutrients and quality crops as well tolerance abiotic stresses. A new biostimulant was developed from sewage sludge through its fermentation with Bacillus licheniformis a plant growth-promoting bacteria (PGPB). The fermented product includes three classes components: B. biomass; enzymatic secretion said microorganism, which mainly peptidases...
In this paper different pre-treatments (involving temperature, pressure and enzymatic processes) were applied to activated sludge from slaughterhouse wastewater treatment with the aim of improving biogas production in anaerobic processes.
Abstract The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation polluted soils. In this manuscript we study under laboratory conditions capacity new biostimulant obtained from slaughterhouse sludge in soil by oxyfluorfen at rate 4 l ha −1 (manufacturer’s recommended) over 90-day period. We determined its effects on dehydrogenase, urease, β-glucosidase and phosphatase activities, microbial community structure evolution herbicide soil....
In this manuscript, we study the manufacture and effect on soils of different edaphic biostimulants/biofertilizers (BS) obtained from sewage sludge using Bacillus licheniformis as biological tool. These BS consist combinations organic matter, bacteria enzymes that were subjected to several treatments. applied in soil order observe their influence biochemical properties (enzymatic activities ergosterol content). Dehydrogenase, urease, β-glucosidase, phosphatase content measured at incubation...
The cheese whey (95% composed of water) is an effluent produced in the industry, which more than 1.5 million tons are generated Spain, constituting a serious environmental problem. process starts with new fermentative/enzymatic technology that totally converts whey, mainly by lactose, proteins, and salts, into fermented product higher added value. This lactic acid bacteria biomass, ammonium lactate, protein hydrolysate. To separate valuable fractions, this processed two-stage membrane...
The objective of this study was to investigate the effect foliar fertilization 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 6 L ha-1 divided into three applications (before flowering, beginning flowering fruit set). BS2 had higher number low molecular weight peptides BS1. contents macro micronutrients leaves, photosynthetic pigments yield were plants...
The objective of this study was to under laboratory conditions the bioremediation effect two biostimulants obtained from okara in a soil polluted by imazamox at rate 2.5 l ha-1 (manufacturer's recommended rate). These were enzymatic hydrolysis processes using one (subtilisine) and (subtilisine flavourzyme) enzymes. Their effects on activities, microbial community structure evolution herbicide over 90-day period. Both stimulated biochemical activity population. However, stimulation greater...
