1. Synthesis of delafossite CuCrO2 via solution combustion method and its acid functionalization for biodiesel production
Abstract CuCrO2 was synthesized by solution combustion synthesis (SCS) and applied as a heterogeneous catalyst to produce soybean biodiesel. The combustion reaction was carried out using urea as a fuel, and copper (II) and chromium (III) nitrates as precursors. After the powders’ obtention, these were calcined and functionalized in an acidic medium. The po

2. Extraction and Characterization of Pequi Seed Oil for Biodiesel Production: A Green Management of Waste to Biofuel Using Ethanol and Heterogeneous Catalysis
This work reports the characterization of a vegetable oil extracted from pequi seeds, an agroindustrial residue, and its biodiesel production using ethanol and heterogeneous catalysis. The pequi seeds showed 40.73 wt.% of extractive content, which represents a large amount of the biomass composition. The crude oil extracted from the pequi seeds with ethanol

3. Economic feasibility of Gluconacetobacter diazotrophicus in carrot cultivation
ABSTRACT The inclusion of more sustainable alternatives such as bacterial inoculants is a viable option for the competitiveness of vegetable crops in tropical countries such as Colombia. The economic feasibility of a bacterial suspension of G. diazotrophicus applied to the carrot crop was determined. The native isolate G. diazotrophicus GIBI029 was evaluated

4. Linear relationships between biometric variables in lettuce seedlings
ABSTRACT Seedling production is an important step in growing vegetables. The study of relationships between variables has applications in practically all areas of study and is useful in identifying relationships among quality variables in vegetable seedlings. Thus, this work aims to estimate linear relationships between biometric variables in lettuce seedlin

5. CONTRIBUTION OF SOIL ATTRIBUTES AND MORPHOLOGICAL VARIABLES TO YIELD OF IRRIGATED GARLIC
ABSTRACT This study aimed to investigate relationships between the soil attributes that most affect garlic yield, which can be useful to choose a new area for the growing of this vegetable. We also aimed to study the effects of irrigation deficit at bulb formation stage (cloves) on final garlic quality and yield. The variables evaluated were garlic yield, ir

6. Physicochemical characterization, carotenoid content and protein digestibility of pumpkin access flours for food application
Abstract Pumpkin (Cucurbita maxima) research has been growing because of its characteristics, such as the attractive color, low-cost production, nutritional potential, and functional properties for food application. In this context, pumpkin processing for flour production provides a full possibility for the consumption of this vegetable, being thus an altern

7. Fatty acid profile and physicochemical, optical and thermal characteristics of Campomanesia adamantium (Cambess.) O. Berg seed oil
Abstract The aim of this study was to characterize the oil obtained from seeds of Campomanesia adamantium by physicochemical quality parameters, oxidative stability, antioxidant activity, quality indexes, optical and thermal stability and its fatty acid profile. These seeds were a relevant source of oil (83 mg g-1) with high potential antioxidant activity (I

8. Yield and morphological attributes of bell pepper fruits under biological fertilizers and application times
ABSTRACT Bell pepper (Capsicum annuum) is one of the most consumed vegetables around the world. Balanced fertilization is essential for growing this vegetable. The objective of this study was to evaluate the yield and morphological attributes of bell pepper under doses and times of application of biological fertilizers. Two experiments were carried out with

9. Quality evaluation of kashar cheese: influence of palm oil and ripening period
Abstract Vegetable oils are used as milk fat replacers in cheese production to alter sensory, nutritional profile, and to produce cholesterol free or low-cost cheeses. The aim of this study is to investigate the effect of palm oil usage on kashar cheese’s physicochemical, textural and sensorial quality characteristics during ripening. The results showed th

10. APROVEITAMENTO DE PRECURSORES LIGNOCELULÓSICOS PARA PRODUÇÃO DE ACETATO DE CELULOSE
The feasibility of obtaining cellulose acetate from lignocellulosic precursors is of great interest from the environmental, economic and technological points of view. Herein, sugarcane bagasse and vegetable sponge (Luffa cylindrica ) were used as precursors to produce cellulose using the organosolv extraction procedure. From the extracted celluloses, the pro

11. PRODUCTIVITY OF IRRIGATED JAMBU UNDER SOIL-WATER STRESSES AND NITROGEN DOSES
ABSTRACT Jambu (Acmella oleracea (L.) R.K.) is a short-cycle leafy vegetable from the Amazon region, which needs an adequate availability of water and nutrients, mainly nitrogen, to obtain a rapid mass increase. This research aimed to study the effect of different soil-water stresses and nitrogen doses on jambu cultivation in the state of Pará. The experime

12. Antimicrobial resistance, diarrheagenic and avian pathogenic virulence genes in Escherichia coli from poultry feed and the ingredients
RESUMO Escherichia coli diarreiogênicas (DEC) e patogênicas para aves (APEC) são associadas a infecções intestinais e extraintestinais (ExPEC), respectivamente. O objetivo do presente trabalho foi avaliar a sensibilidade antimicrobiana, a presença de genes que codificam os fatores de virulência relacionados à DEC e APEC, e a classificação filogené
