Cyperus esculentus L. var sativus is cultivated in Spain, only in the L’Horta Nord in the Valencia region. In this country, tubers are consumed fresh to make a popular beverage in the Valencia region called “horchata de chufa” (chufa milk). This drink is considered beneficial for human health thanks to its high nutritional value and medicinal impor...
Agricultural waste availability implies the possibility of recovering energy as biomass. The collateral effect is the production of ashes that, in some cases, have the potential to be reused in the manufacture of cement, mortar, and concrete. This article presents the study of the auto-combustion (unlike all previous studies) of corn (maize) straw...
Introduction
Fungal pathogens cause major yield losses in agriculture and reduce food quality and production worldwide.
Purpose
To evaluate new safer alternatives to chemicals for disease management and preserve the shelf life of food, this research was conducted to: determine the chemical composition of the essential oils (EOs) of Thymus serpyllu...
The postharvest life of most fruit and vegetables is limited by fungus proliferation. The Aloe vera gel was added at different concentrations to test its antifungal potential against five fungi (Rhizoctonia solani, Curvularia hawaiiensis, Botryotinia fuckeliana, Penicillium italicum, Verticillium dahliae), which cause significant losses in basic ag...
The postharvest life of most fruit, vegetables and cereals is limited by fungal proliferation. The chemical composition of Mentha piperita, M. spicata and M. suaveolens essential oils (EO), and the antifungal activity against four pathogenic and post-harvest fungi isolated from food, were herein investigated to evaluate their potential as natural f...
The European Union is promoting regulatory changes to ban fungicides because of the impact their use has on the ecosystem and the adverse effects they can pose for humans. An ecofriendly alternative to these chemicals to fight against fungal species with low toxicity is essential oils and their compounds extracted from aromatic plants. The purpose...
Soil stabilization using cementing materials is a well-known procedure for earth-based building blocks preparation. For the selected binding materials, innovation usually focuses on low carbon systems, many of which are based on alkaline activation. In the present paper, blast furnace slag (BFS) is used as a mineral precursor, and the innovative al...
Arundo donax is a plant native to Asia and is considered an invader species in the Mediterranean region and many tropical zones in the world. These invader plants can be collected to produce a biomass, which can be converted to ash by combustion. The scope of the study is to assess the use of these ashes (Arundo donax straw ash [ADSA]) as supplemen...
Many agrowastes are being used for energy production by combustion in power plants. This process generates huge amounts of ash, which has a potential pozzolanic activity for blending with Portland cement or hydrated lime. In this paper, the ash obtained from elephant grass ( Pennisetum purpureum Schum var. purple ) leaves (EGLs) was studied, includ...
Films based on starch-gellan blends at 9:1 and 8:2 ratios containing emulsified or lecithin encapsulated thyme (Thymus zygis) essential oil (EO) (0.25 or 0.5 g/g polymer), were obtained by casting method and characterized as to their structural, functional (mechanical, barrier and optical) and in vitro antifungal properties against Alternaria alter...
The chemical composition of commercial Syzygium aromaticum, Cinnamomum verum, and Laurus nobilis essential oils as well as their antifungal activity against four pathogenic fungi isolated from Mediterranean rice grains has been investigated. Eighty nine compounds accounting for between 98.5 and 99.4% of the total essential oil were identified. The...
Aloe vera gel, analysed as to its antifungal properties against six fungi causing plant diseases, was found to be most effective against Fusarium oxysporum. It was included in different ratios in starch based films plastiziced with glycerol to obtain antifungal films. These were characterized as to their physical (barrier and optical) and structura...
Biomass waste from rice straw has many management problems, including field firing causing severe air pollution and natural organic decomposition resulting in methane emission. The conversion of this waste to ashes may offer the possibility of reusing them in cementing systems. For the first time ashes from different parts of the rice plant (Oryza...
El presente trabajo recoge parte de los resultados obtenidos en el marco del proyecto de innovación docente “Herramientas para la planificación, realización y valoración de los Trabajo Fin de Grado (TFGs)”. Se pretende resolver la problemática a la que se enfrenta el alumnado, los tutores y los tribunales en cuanto a los criterios de valoración de...
Commercial thyme and lavender essential oils were analysed by GC/MS. Sixty-six compounds accounting for 98.6–99.6% of total essential oil were identified. Thymol (52.14 ± 0.21%), followed by p-cymene (32.24 ± 0.16%), carvacrol (3.71 ± 0.01%) and γ-terpinene (3.34 ± 0.02%), were the main compounds in thyme essential oil, while large amounts of oxyge...
The antimicrobial activity of essential oils (EO) is very well-known and it has been reported that incorporating them into edible films based on biopolymers extends the food's shelf-life. In this study, cinnamon, clove and oregano EO, at 25% with respect to the polymer, were incorporated into glycerol plasticized starch-gelatin blend films (ratio 1...
Agrowastes are produced worldwide in huge quantities and they contain interesting elements for producing inorganic cementing binders, especially silicon. Conversion of agrowastes into ash is an interesting way of yielding raw material used in the manufacture of low-CO

binders. Silica-rich ashes are preferred for preparing inorganic binders. Sugar...
Chemical composition of commercial Origanum compactum and Cinnamomum zeylanicum essential oils and the antifungal activity against pathogenic fungi isolated from Mediterranean rice grains have been investigated. Sixty-one compounds accounting for more than 99.5% of the total essential oil were identified by using gas chromatography (GC) and gas chr...
Essential oils of bay leaf, cinnamon, clove and oregano were tested in vitro and oregano essential oil in vivo, against two foodborne fungi belonging to the dominant mycobiota of stored rice, Fusarium culmorum and Fusarium verticillioides, collected from the Albuferarice-producing Mediterranean area near Valencia (Spain). Chemical composition was i...

En la actualidad, el uso de plaguicidas químicos aún resulta necesario para controlar e incrementar los rendimientos agrícolas, pero en los últimos años el uso abusivo de estos productos ha desencadenado una serie de alteraciones medioambientales, que han influido en el deterioro del suelo, la pérdida de biodiversidad, y el aumento de las enfermeda...
This paper reports the in vitro antagonism of an isolate of Trichoderma harzianum under a range of water (0.85–0.995 aw) and temperature (15–25°C) regimes when associated with two phytopathogenic fungi: Rhizoctonia solani and Verticillium dahliae. The effects of ecophysiologic factors on the individual and dual growth of these fungal species were i...
El género Trichoderma incluye un gran número de especies y cepas reconocidas como agentes de biocontrol (BCAs). El uso de este género para el control de las enfermedades de las plantas es una alternativa muy prometedora al uso de compuestos químicos. La utilización de especies y cepas de Trichoderma como antagonistas de diferentes hongos está ampli...
The antibiotic activity of 70 isolates belonging to the genera Aspergillus, Penicillium, Fusarium, Alternaria and Trichoderma was tested as preliminary screening. The highest activity was obtained with three Penicillium oxalicum isolates, one Penicillium decumbens isolate and the Trichoderma harzianum isolate. After that, we chose these five isolat...
