Lippia gracilis, popularly known in Brazil as 'alecrim-de-tabuleiro', is used for many purposes, especially antimicrobial and antiseptic activities. The leaves of three L. gracilis genotypes, including LGRA-106, LGRA-109 LGRA-110 were collected from the Active Germplasm Bank located "Campus Rural da UFS" research farm at São Cristóvão country, Sergipe State, Brazil. essential oils obtained plants by hydrodistillation. Chemical analysis was performed gas chromatography-mass spectrometry...
Abstract Background Bacillus thuringiensis ( Bt) is a widely used biopesticide. The bioinsecticide based on Bt obtained by fermentation, but the substrates currently for its production constitute ingredients of high commercial value. In this context, use agro-industrial residues as an alternative to make fermentation process viable large scale, in addition minimizing environmental problems and contributing destination these biotechnological purposes. Results first part study, previously...
Abstract The aim of this study was to investigate the anti-biofilm activity two essential oils from Varronia curassavica Jaq. Two genotypes (VCUR-202 and VCUR-302), previously identified as exhibiting high antimicrobial against Xanthomonas campestris, were selected for study. Use Crystal Violet (CV) Phenol Red (PR) staining biofilm biomass demonstrated that both Essential Oils (EOs) had strong effect on formation preformed biofilm. EOs effects confirmed with scanning electron microscopy...
Leishamaniasis is a disease that affects more than 2 million people worldwide, whose causative agent Leishmania spp. The current therapy for leishmaniasis far from satisfactory. All available drugs, including pentavalent antimony, require parenteral administration and are potentially toxic. Moreover, an increase in clinical resistance to these drugs has been reported. In this scenario, plant essential oils used traditionally folk medicine emerging as alternative sources chemotherapeutic...
Thirteen reference genes were investigated to determine their stability be used as a housekeeping in gene expression studies skeletal muscle of chickens. Five different algorithms for ranking and results suggested that individual rankings the differed among them. The validated using samples obtained from Pectoralis major chicken. Samples chickens development periods post hatch under nutritional diets. For calculation ΔΔCt approach was applied compare relative pairs within each 52 when...
This study evaluated the effects of Eimeria spp. challenge and dietary supplementation with free methionine or dipeptide on animal performance; expression genes associated immune system, antioxidant amino acid transport in jejunum; redox status jejunum broiler chickens.A randomized, 2 × 3 factorial design was used, which first factor (Eimeria-challenged, EC, unchallenged, UC, broilers) second (non-supplemented, NS; dl-methionine, dl-Met; dipeptide, dl-methionyl-dl-methionine, dl-MMet). At 14...
Since cinnamon has vitamins and minerals in addition to antioxidants compounds its chemical composition studies have shown the potential of supplementation on some important characteristics performance birds. Thus, this study was conducted under hypothesis that inclusion laying quail diet could influence birds through expression genes related antioxidant activity lipid metabolism. To test hypothesis, 144 Japanese (Coturnix japonica) with an initial age 18 weeks average weight 133g were...
Maytenus rigida Mart (Celastraceae), conhecida por "Bom-homem", "Bom-nome", "Cabelo-de-negro", "Casca-grossa" e "Pau-de-colher", é uma arvore de pequeno porte. A entrecasca do caule empregada popularmente no Nordeste Brasil tratamento das dores em geral, infecções inflamações. O presente trabalho avaliou tanto o perfil fitoquímico M. meio um roteiro analítico, quanto à atividade antibiótica dos extratos pelo método Kirby-Bauer modificado. Os resultados demonstraram que os etanólico, aquoso,...
The aim of this study was to evaluate the effect dietary lysine on performance, protein deposition and respiratory chain gene expression in male broilers. A total 252 Cobb 500 broilers were distributed, a completely randomized design, into four treatments with seven replicates nine birds per experimental unit. Experimental consisted diets based corn soybean meal, levels digestible lysine: 1.016%, 1.099%, 1.182% 1.265%. increase level diet provided higher weight gains, feed efficiency body...

Abstract Chalcone ( E )‐1,3‐diphenyl‐prop‐2‐en‐1‐one and a series of 14 methoxylated derivatives have been synthesized via Claisen–Schmidt aldol condensation characterized by FTIR, CG/MS/DIC, 1D 1 H 13 C), 2D (COSY, HSQC, HMBC) NMR, EMAR techniques. All molecules were tested at mM concentration for antifungal Sclerotium sp., Macrophomina phaesolina Colletotrichum gloeosporioides ), antibacterial Acidovorax citrulli two strains), antiprotozoal Phytomonas serpens) activities.

Neste trabalho foi avaliada a atividade inibitória da acetilcolinesterase (AChE) pelo método de Ellman, modificado por Rhee, extratos aquosos e etanólicos oito plantas utilizadas na medicina popular região Nordeste do Brasil. O extrato aquoso E. velutina não apresentou enquanto o Maytenus rigida baixa (percentual inibição 4%). Detectou-se moderada com P. piperoides 40 %), V. agnus-castus L. inibiu 74% AChE, caracterizando-se como potente inibitória. A avaliação AChE os demonstrou que...
A inoculação de estirpes rizóbios em sementes feijão-de-porco (Canavalia ensiformis), caupi (Vigna unguiculata) e guandu (Cajanus cajan), recomendadas para outras regiões do País, não tem resultado incrementos nas taxas fixação biológica N2 nem no crescimento dessas leguminosas solos dos tabuleiros costeiros Sergipe. Os objetivos deste trabalho foram avaliar a eficiência simbiótica nativos associados essas tolerância deles estresses. Das 17 isoladas analisadas casa vegetação, quatro...
Abstract Xanthomonas campestris pv . (Xcc) is a phytopathogenic bacteria, and it the causative agent of black rot in crucifers. Recent studies have shown that Bacillus species strong biological control on One mechanisms this secondary metabolites production. A collection 257 bacteria isolated from suppressive soil was evaluated for vitro antagonistic activity against X. , 92 isolates (44.6%) were able to inhibit its growth. Among double‐layer technique, 51 (55.43%) inhibited Xcc growth...
Xylanases have gained increasing importance due to their diverse applications in the food, paper, and pharmaceutical industries, however, production of these enzymes currently uses expensive substrates. It has already been estimated that more than 30% enzyme cost originates from substrate. The present study aimed optimize extracellular xylanases by Bacillus sp. TC-DT 13 using solid-state fermentation with agro-industrial residues, a view at reducing enzymes. All residues were tested...
