The tomato (Solanum lycopersicum L.) is one of the many essential vegetables around world due to its nutritive content and attractive flavor. However, short shelf-life postharvest losses affect marketing. In this study, effects chitosan-Ruta graveolens (CS + RGEO) oil coatings on quality Tomato var. “chonto” stored at low temperature (4 °C) for 12 days are reported. film-forming dispersions (FFD) were eco-friendly synthesized presented viscosities (between 0.126 0.029 Pa s), small particle...

Drug resistance in antifungal therapy, a problem unknown until few years ago, is increasingly assuming importance especially immunosuppressed patients and receiving chemotherapy radiotherapy. In the past years, use of essential oils as an approach to improve effectiveness agents reduce levels has been proposed. Our research aimed evaluate activity Colombian rue, Ruta graveolens, oil (REO) against clinical strains Candida albicans, parapsilopsis, glabrata, tropicalis. Data obtained showed...

Guava is a fruit appreciated worldwide for its high content of bioactive compounds. However, it considered highly perishable fruit, generally attacked by pathogenic species such as the fungi Colletotrichum gloeosporioides, which causes anthracnosis. To diminish losses caused fungi, coatings chitosan (CS) with Ruta graveolens essential oil (RGEO) in different concentrations (0.5, 1.0, 1.5% v/v) were applied situ and their effects on physical properties microbiological quality guavas studied....

This research aimed to evaluate the impact of atmospheric cold plasma (ACP) treatment on fungal spores naturally present in sundried tomatoes, as well their influence physico-chemical properties and antioxidant activity. ACP was performed with a Surface Dielectric Barrier Discharge (SDBD), applying 6 kV at 23 kHz exposure times up 30 min. The results showed significant reduction mesophilic aerobic bacteria population filamentous fungi after longer exposure. In particular, effect assessed...

Anthracnose of papaya ( Carica L.) caused by the fungus Colletotrichum spp. is one most economically important postharvest diseases. Coating with chitosan (CS) and Ruta graveolens essential oil (REO) might represent a novel eco-friendly method to prevent anthracnose infection. These compounds show both antimicrobial eliciting activities, although molecular mechanisms in have not been investigated date. In this study, effectiveness CS REO alone combined (CS-REO) on fruit during storage were...

Pears (Pyrus communis L.) cv. Packham’s Triumph are very traditional for human consumption, but pear is a highly perishable climacteric fruit with short shelf-life affected by several diseases microbial origin. In this study, protective effect on the quality properties of pears was evidenced after surface application chitosan-Ruta graveolens essential oil coatings (CS + RGEO) in four different concentrations (0, 0.5, 1.0 and 1.5 %, v/v) during 21 days storage under 18 °C. After treatment,...

Here, we report for the first time on mechanisms of action essential oil Ruta graveolens (REO) against plant pathogen Colletotrichum gloeosporioides. In particular, presence REO drastically affected morphology hyphae by inducing changes in cytoplasmic membrane, such as depolarization and fatty acid profile where straight-chain acids (SCFAs) increased up to 92.1%. addition, induced fungal metabolism triggered apoptosis-like responses cell death, DNA fragmentation accumulation reactive oxygen...

Colombia is the fourth global producer of palm oil and, according to national agenda R+D, solving needs production chain a high priority for Colombian government; this reason, application biorefinery concept can represent solution. In work, an approach based on economic evaluation, techno-economic sensitivity analysis and indicators was used development lineal in order quantify improvements implementation. Results showed that processing capacity 240,000 tons per year bunch with plant life 15...

Agricultural food production is greatly affected by postharvest diseases worldwide, such as the caused Alternaria species, which are very common in several crops. The management of fungal infections around world largely relies on fungicides. In this context, control early blight solani potatoes and linariae tomatoes has mainly consisted application fungicides, with negative impacts environment human health. Recently, ‘omics’ gene editing through CRISPR/Cas9 system RNAi technologies...

The influence of Anatasa/Rutile ratio on TiO2 films, grown by electrophoretic deposition was studied in the photoassisted electrolytic copper ions removal from cyanide solutions. proper dispersant dosage allowing simultaneous Anatase and Rutile chosen based electrokinetic measurements; evidenced XRD spectra formed films. evaluation films ion showeds that it is possible to enhance activity adding some exploiting synergetic interaction between these two materials, achieve its deposition.

Microalgae are a promising source of energy and its principal advantage that does not compete with the feeding supply. Besides, microalgae have other benefits, such as use infertile land for cultivation seawater flue gas nutrients source. Exergy analysis is useful tool measure quantity quality sources studies sustainability process. This methodology requires analysing material flows each stage production In this study, exergy was applied to one scenario taking capacity 100 t/y biodiesel from...

The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals.Part these studies consists making structural modifications to pesticides for commercial purposes increase efficacy.In this article, we present four new pyrazol-4-carboxamide 8a-8d derivatives (PCD), through a four-step synthetic protocol, starting with edaravone 1 primary amines like benzo-fused, aliphatic, hydrazines, process low environmental impact.Synthesized were...

An increasing interest exists in the use of ethanol as substitute fossil fuels which can be obtained from renewable resources, microalgae are a promising source for third generation bioethanol due to high percentage carbohydrates/polysaccharides presents some species and thin cellulose walls. Ethanol produced either biomass before lipid extraction or cake after cell disruption oil extraction. Second option gives interesting possibility producing both biodiesel same biomass. Energy analysis...

One of the main challenges in chemical industry is to reduce dependence on fossil fuels and emission greenhouse gases through use renewable raw materials. The International Energy Agency (IEA) has identified biomass as future technology mitigate this effect, which can be achieved synthesis (Syngas) fuel for energy generation. On other hand, cogeneration systems using microturbine are appropriate technologies take advantage available exhaust that generally wasted conventional power generation...

Environmental pollution and declining reserves of fossil fuels has generated the need for new sources energy that are renewable, is how in last decade have called biofuels, among which mainly bioethanol biodiesel. Palm oil, soybean sunflower at moment, most used raw materials, but some authors claim use these seeds generates competition with human food aggravating problem monoculture. Based on questions second generation biofuels represent a great advantage since they characterized by...
